Method for driving motors and apparatus for driving motors |
摘要 |
A method is provided for driving a motor apparatus having a first motor, a second motor, and a motor power supply commonly used for the first motor and the second motor. The first motor is a brushless motor. An electrical power is supplied from the motor power supply to driving circuits of the first motor and the second motor through a common motor power supply line. The first motor is driven by a direct PWM driving method, and the second motor is driven by a method different from the direct PWM driving method. A reverse regeneration current generated in the first motor is flown to the second motor through the common motor power supply line.
