While the UAV market is booming, the industry chain of UAVs has also ushered in the development opportunities. Undoubtedly, miniature brushless DC motors are one of the most important components of UAVs, and their performance is directly related to the flight performance of UAVs, so the market for high-quality, high-performance and long-life brushless UAV motors is gradually expanding.
The main components of a drone include flight control and remote control. The key to determining whether a drone is a professional or consumer is whether it has an intelligent flight control system and special functions. In principle, one motor needs to be equipped with an 8-bit MCU for control, but there is also a solution where one MCU can control multiple brushless DC motors.
The increase in acceleration and weight will bring greater pressure to the entire motor system. When the motor control system detects an angle change, it can control the motor to rotate in the opposite direction to achieve stable results. Professional drones require at least four to six brushless motors to drive the drone's rotor, and the motor drive controller is used to control the speed and direction of the drone. The motor control system is very important for the stability of the drone, Therefore, the motor system of professional drones should be more accurate and reliable.
The DC brushless motor used by drones has certain technical requirements in terms of structural design and motor control algorithms, and requires strict performance testing and technical verification systems to ensure the reliability of the product.
The quality of drone brushless motors is also crucial for their stator winding technology. Nowadays, fully automatic winding machines are mostly used for coil winding. Some manufacturers wind them themselves, while others process them on behalf of others. Regardless, it is necessary to choose good winding machine equipment because there are certain requirements, including inter turn, resistance, voltage resistance, leakage value, inductance, etc., and the wound stator needs to be inspected and qualified before use, So the quality of the drone is poor when it comes to wiring, which is also an important reason.
Brushless motor automatic production line is widely used in many manufacturers, to a large extent, improve the production efficiency, but brushless motor automatic production line should be caused by the corresponding pitfalls of the wide enough attention, the following aspects of a few easy to cause safety hazards for a brief description.
1, to ensure that the machine does not have no accident, not only the machinery does not have to meet the safety requirements, and more importantly, the author is required to strictly abide by the safety program, the safe operation of the program due to the different equipment, but the safety of this Ning is similar.

5. The safety devices of the brushless motor automatic production line must be used correctly according to the regulations, and it is forbidden to remove them for use. The tools, fixtures and processed parts used in the brushless motor automatic production line must be firmly mounted and must not be loosened.
6, brushless motor automatic production line in operation, the operator shall not leave the post, in order to prevent the occurrence of problems no one to dispose of, it is strictly prohibited to adjust the operator's hands, not the hand measurement of the parts, or lubrication, cleaning debris and so on.
7, the operator found abnormal sound, or other abnormalities, should be shut down and power off to check and feedback to the relevant personnel in charge, can not be unauthorized maintenance operations, electricity and equipment must be installed and overhauled by an electrician, to do not carry electricity to repair, maintain a good grounding to prevent leakage of electricity.
8, in the case of voltage does not steal, should be stopped on the brushless motor automatic production line operation, should be promptly disconnected, take appropriate measures to solve. Streamline operation roaming to the blackout situation, need to immediately close the electric room, to prevent re-call, the equipment in the state of no control operation.
9. After the end of the work, should cut off the power supply, the tool and the workpiece from the work position exit, and organize the work site will be parts, fixtures, etc. placed neatly, clean up the brushless motor automatic production line of health.
10. The operation site of brushless motor automatic production line should have a good environment, that is, the brightness should be live appropriate, the noise and vibration should be small, the parts, jigs and fixtures, etc. should be placed neatly. Brushless motor automatic production line should be based on its performance, operation sequence, etc. to develop a safe operating procedures and inspection, lubrication, maintenance and other systems, so that the operator to comply with.
Rotary transformer is an induction miniature motor, its output voltage and rotor angle to maintain a certain functional relationship, it is the angular displacement will be converted into an electrical signal displacement sensor, but also can perform the coordinate conversion and function calculation of the solving element, so the rotary transformer principle of operation is how? How is the application development?
1. The working principle of the resolver:
The essence of the rotary transformer is a transformer, the key parameters are similar to the transformer, such as the rated voltage, rated frequency and transformer ratio, and the difference between the transformer is that the primary side and the secondary side is not a fixed installation, but the relative movement, with the change of the relative angle of the two, you can get the amplitude change of the waveform on the output side.
3. The development of the application of the resolver:
Rotary transformer is currently mainly used in the angular position servo control system, commonly used for angular position detection and measurement.
With the development of electronic technology, the integration of electronic components has increased, while the price of components has decreased significantly; In addition, with the progress of signal processing technology, the signal processing circuit of the resolver has become simple, reliable and the cost has dropped dramatically. Moreover, there has been a software decoding signal processing, which makes the signal processing problem more flexible and convenient, so that the application of the resolver has been further developed, its advantages have been further embodied, I believe that in the future, the development of the resolver has been popularized, to bring more gospel to our production life!
For most of the motor manufacturers, stator winding work is basically a winding machine to complete, but many friends reflect that their winding machine running, the noise is very large, feel very irritable, that is in itself so noisy, or the machine has a problem?
Understand some mechanical people should know that the noise is mainly due to vibration, so how does vibration come? Generally speaking, there are mainly not centered, quality imbalance, bearing failure and mechanical loosening caused by several reasons.
1. The alignment of the machine is very important, so is the winding machine, if it is not centered, it may apply stress to the bearings and parts. Generally there are mainly parallelism and angular reasons, common installation of the original components relative position movement, system pressure leads to distortion, temperature changes lead to deformation of the machine, fixed bolts when the offset, coupling surface and axis is not perpendicular and so on.
2. Mass imbalance, mainly due to the mass and geometric centerline is not aligned with the abnormal state caused by. When the spindle of the winding machine rotates, its center of gravity generates a centrifugal force acting on the bearings, and the magnitude of this force varies steadily with the rotation of the spindle. Three types of imbalance exist: static or force imbalance, moment imbalance or even imbalance and dynamic imbalance.
3. Bearing failure, rolling bearing fatigue spalling, wear, plastic deformation, corrosion, glue and cage damage; sliding bearing busbar alloy loosening, busbar alloy damage, axial tile loosening, bearing clearance is too large.
4. Mechanical looseness, there are two types of looseness: rotational looseness and non-rotational looseness, bearing wear may lead to rotational looseness. When detecting this fault, signs of bearing wear will be detected first and then bearing looseness will occur. Looseness may lead to other malfunctions or other failures of the machine. Wear and distortion of mechanical parts, misalignment and imbalance of the shaft system, etc., as well as looseness may interact with each other.
These are the main reasons for the noise noise of the stator winding machine, mastering these basic knowledge, in order to ensure the stable operation of the winding machine, normal work.
Motor stator automatic winding machine belongs to the more sophisticated equipment, each step of each link of the operation is very important, if not done properly, it is likely to lead to a variety of problems in the line winding, and even the machine is faulty, the following take a look at it!
1, first determine the parameters, imported programs should also pay attention to look at the first modified, the first modified to note the location of the winding point, make sure that there is no error, slowly idling a few times to try to see the starting point as well as the winding path, parking, winding width and so on there is no problem.
2. Start the normal winding process, regardless of the sample line neatly or not, we must check the following conditions:
a. Whether the start winding point is too front or too back.
b, the line is too sparse or too dense, it is likely that the wire diameter setting does not meet the requirements.
c, the line is getting faster or slower, you can fine-tune the size of the wire diameter: the faster you need to change slightly smaller, the slower you need to change slightly larger.
d. Some of the wound stator needs to be wound multi-layer, pay attention to check whether it is due to the phenomenon of deformation after winding multi-layer.
e, enameled wire general wire diameter size for the actual wire diameter, in the setting of the need to add the thickness of the enamel is correct.
f, after the completion of the winding, the rewinder or not should also pay attention to. Sparse winding row, start winding point is best to forward, the width is best to narrow a little.
3. After winding one or several products, you need to do the pinhole test, no bubbles, in line with the national standard range can be, otherwise the quality will not pass, will affect the quality of the product and the effect.
The above is the motor stator automatic winding machine winding steps and details of the matter, no matter who uses, should pay attention to these basic details, so as to ensure the normal and stable operation of the equipment.
Brushless DC motors have a fast response time, high starting torque, and can provide rated torque performance from zero speed to rated speed.Brushless DC motors are widely used.Typically, brushless DC motors can be categorized into the following three main applications:
1. Continuous load application: mainly used in industries that require a certain speed, but do not need high speed accuracy, such as fans, pumps, vacuum cleaners, hair dryers appliances and so on, the cost is relatively low, most of the open-loop control.
2. Variable load applications: mainly need to change the speed within a certain range of applications, and the motor speed characteristics and dynamic response time characteristics have higher requirements. For example, dryers and compressors in household appliances.
