Abstract

In order to reduce the complexity of traditional motor test, this chapter presents a no-coupling test method for brushless DC motor based on parameter identification techniques. Based on the motor’s dynamic mathematical model, the parameters, such as the motor coil resistance, back EMF coefficient, rotary inertia, and damping coefficient can be obtained just through measuring the motor input voltage, motor current, and motor speed. The motor’s characteristics and other physical parameters can also be obtained based on the identified parameters. Simulation result validates that the test method is feasible and has high precision. The no-coupling test method provides an easy and quick method and can effectively solve the problem of traditional motor test.
