Title:
METHOD FOR CONTROLLING ELECTRIC MOTOR
Document Type and Number:
Japanese Patent JP2017200432
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for controlling an electric motor.SOLUTION: A method for controlling an electric motor having a rotor is provided. The method is implemented after a shutdown of the motor has been initiated. The method includes: starting a timer in a motor controller; performing regenerative braking to recapture kinetic energy from the rotor as electrical energy; using the recaptured electrical energy from the regenerative braking to power the motor controller; and, if the timer in the motor controller exceeds a predetermined timer value, setting a flag in memory in the motor controller to indicate that the motor has stopped.SELECTED DRAWING: Figure 3
