  • Motor driving control apparatus and electric apparatus
    Patent number: 10870355
    Abstract: This motor driving control apparatus has (A) an inverter unit configured to drive a motor; (B) a separation switch configured to separate a power source from the inverter unit; and (C) a controller configured to instruct the separation switch to separate the power source from the inverter unit and control the inverter unit to perform switching according to a speed and a braking target torque, upon detecting an event that braking should be performed without passing a regenerative current to the power source from the inverter unit. By introducing the separation switch that operates as described above, it becomes possible to perform control so as to consume the power by the motor itself without passing the regenerative current to the power source such as a battery.
