Latest Patents
Ootake's latest patents include a motor control device and a rotary electric machine control device. The motor control device is designed to control the energization of a motor by interchangeably converting direct current electric power from a power source and alternating current electric power of the motor. This is achieved through a power conversion circuit that adapts to the motor's running and regenerative operations. Additionally, a voltage instruction value calculation unit plays a crucial role in calculating q-axis and d-axis voltage instruction values through feedback control of dq-axis currents. The device also features a voltage instruction value limit unit that prioritizes limiting the q-axis voltage instruction value during regenerative operations.
The rotary electric machine control device consists of control circuits that manage inverter circuits corresponding to selected drive modes. These modes include a cooperative drive mode, which allows for current supply control to motor windings through inter-computer communication, and independent and one-system drive modes, which operate without such communication. This versatility in control modes enhances the output characteristics of the motor.
