Abstract
Embodiments of this application provide a method and system for measuring motor damping. In the method for measuring motor damping, a driving signal is generated to drive a to-be-tested motor to operate, and at a cut-off moment of the driving signal, the to-be-tested motor enters a free damping state and a turn-off signal is generated at this moment to cut off a test circuit of the to-be-tested motor. In this way, an acceleration of the to-be-tested motor having the test circuit cut off and in the free damping state can be acquired, and damping of the to-be-tested motor is obtained by using the acceleration of the to-be-tested motor having the test circuit cut off and in the free damping state, thereby realizing the measurement of the damping of the to-be-tested motor.
