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.
Claims8
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 regarding a fault of the second controller itself.
