  • Noise filtering method for motor, recording medium thereof and motor control circuit
    Patent number: 11070150
    Abstract: The invention provides a noise filtering method for a motor. The motor rotates according to an operating voltage. The noise filtering method includes: setting an inspection period and a minimum threshold. The noise filtering method further includes: generating a pulse signal according to the operating voltage, determining whether a time corresponding to each sub-pulse signal in the pulse signal meets the inspection period, and determining whether a pulse width corresponding to each sub-pulse signal is equal to or greater than the minimum threshold. A recording medium storing a program code corresponding to the method, and a motor control circuit for executing the program code are also provided.
    Type: Grant
