Abstract
A rotary breaker that interrupts a transmission of a driving force from a motor to a drive mechanism unit is provided between the motor having a permanent magnet incorporated therein and the drive mechanism unit of an electric vehicle. A second controller controls the rotary breaker based on operation states of a power converting unit that has a power converter that drives the motor by converting a direct-current voltage or an alternate-current voltage into an alternate-current voltage with an arbitrary frequency and a first controller that controls the power converter, operation states of the motor and the rotary breaker, and an operation state of the second controller itself.
Claims9
A drive control system comprising a motor that incorporates therein a permanent magnet and a drive control device that controls the motor, the drive control system being applied to an electric vehicle having the drive control device and the motor incorporated thereon, wherein
- a rotary breaker that interrupts a transmission of a driving force from the motor to a drive mechanism unit is provided between the motor and the drive mechanism unit of the electric vehicle, and
- the drive control device includes:
- a power converting unit that has a power converter that drives the motor by converting a direct-current voltage or an alternate-current voltage into an alternate-current voltage with an arbitrary frequency, and a first controller that controls the power converter;
- and
- a second controller that controls the rotary breaker based on operation states of the power converting unit, the motor, and the rotary breaker, and an operation state of the second controller itself.
