Brushless DC motor is a kind of motor widely used in modern industry, which has the advantages of high efficiency, low noise and low vibration. However, in the process of using brushless DC motors, some problems will be encountered, such as excessive noise, excessive vibration, mechanical damage and so on. This article will discuss the causes and solutions of these problems of brushless DC motors.
I. Excessive noise
Excessive noise in brushless DC motors is a common problem, and its main reason is the instability of the magnetic field between the motor rotor and stator. This instability causes the motor rotor to vibrate, which leads to excessive noise. Here are a few solutions:
1. Optimise the magnetic field design of the rotor and stator. By optimising the magnetic field design of the rotor and stator, the noise of the motor can be reduced.
2. Use better bearings. Adopting better bearings can reduce the vibration and noise of the motor. 3.
3. Reduce the speed of the motor. Reducing the speed of the motor can reduce the noise of the motor.
Excessive vibration
Excessive vibration of brushless DC motor is also a common problem, the main reason is the imbalance between the motor rotor and stator. The following are several solutions:
1. Add balancing block. Adding balancing blocks can balance the imbalance between the motor rotor and stator, thus reducing the vibration of the motor.
2. optimise the design of the rotor and stator. By optimising the design of the rotor and stator, the imbalance of the motor can be reduced, thus reducing the vibration of the motor.
3. Select better bearings. Choosing better bearings can reduce the vibration of the motor.
Mechanical damage
Mechanical damage of brushless DC motors is also a common problem, the main cause of which is the wear and tear between the motor rotor and stator. Here are several solutions:
1. Use better materials. Using better materials can reduce the wear between the motor rotor and stator.
2. add lubricant. Adding a lubricant will reduce the wear between the motor rotor and stator.
3. Regular maintenance. Regular maintenance will keep the motor in good condition and reduce the wear and tear of the motor.
Brushless DC motors have a wide range of applications in modern industry, but in the process of using them, they will encounter problems such as excessive noise, excessive vibration and mechanical damage. The main causes of these problems are instability, imbalance and wear between the motor rotor and stator. These problems can be solved by optimising the design of the rotor and stator, using better bearings and materials, adding balancing blocks and lubricants, and reducing the speed of the motor.
