Fırçasız DC motor parametreleri gereksinimleri ve demontaj ve bakım hususları

Those who have known brushless DC motors know that they are composed of a main body and driver without brushes and commutator (or slip ring), and are typical electromechanical products, so what parameters do you need to pay attention to when choosing a brushless DC motor? In the use of brushless DC motors, how to disassemble maintenance and what matters to pay attention to!

I. Brushless DC motor parameters

1. Large torque, which can be obtained by increasing load torque, moment of inertia and friction.

2. Square modulus torque, which can be considered as the continuous output torque required for practical applications, determined by large torque, load torque, moment of inertia, acceleration, deceleration and running time.

3. Speed: This is the speed with application requirements, which can be determined from the speed trapezoidal curve of the motor to determine the speed requirement of the motor.

Second, disassembly maintenance and precautions

1. Before disassembly, use compressed air to blow off the dust on the surface of the brushless DC motor to keep it in clean condition.

2. Be familiar with the structural characteristics and maintenance technical requirements of brushless DC motor.

3. Prepare the necessary tools for disassembly.

4. If the conditions allow, the motor load test run, detailed inspection of the motor temperature of various parts, sound, vibration, etc., and test the voltage, current, speed, etc., record the load current and no-load loss.

5. Cut off the power, unplug the external wiring of the motor, and record.

6. Select a megohmmeter with appropriate voltage to test the insulation resistance of the motor.

7.Test the absorption rate K. When the absorption rate is greater than 1.33, it means the motor insulation is not damp or the degree of dampness is not serious.

These are the requirements of brushless DC motor parameters and disassembly and maintenance work, master these basic knowledge and skills, the motor will be better and longer life!
