ON-VEHICLE ACTUATOR SYSTEM
First Claim
Patent Images
1. An on-vehicle actuator system comprising:
- a motor driven by a 3-phase current;
an inverter circuit having switching devices to drive the motor;
a power supply system connected to the inverter circuit to supply electricity to the motor and the inverter circuit; and
a control unit to control a current or voltage applied to the motor by controlling an operation of the switching devices;
wherein the control unit controls the motor so that the motor is always supplied an electricity from the power supply system or that the motor does not supply an electricity to the power supply system at all.

Abstract
A motor is controlled to always consume power supplied from a power supply system or not to supply power to the power supply system, by performing control to advance or delay a phase of a 3-phase current flowing in the motor or to reduce a percentage of the generated torque with respect to an effective value of the 3-phase current of the motor, or by applying a d-axis current to the motor.

15. An on-vehicle actuator system comprising:
-
a motor driven by a 3-phase current; an inverter circuit having switching devices to drive the motor; a power supply system connected to the inverter circuit to supply electricity to the motor and the inverter circuit; and a control unit to control a current or voltage applied to the motor by controlling an operation of the switching devices; wherein the control unit calculates power of the motor and controls the motor so that the motor consumes power at all times or that its power consumption does not become negative at all.
