MOTOR APPARATUS CONTAINING INVERTER CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a motor apparatus in which an inverter circuit damage due to a noise hardly occurs by preventing the inverter circuit from being destroyed by applying an overvoltage to a Vcc input terminal by the flow of current even to control voltage (Vcc) wiring, if a switching noise or a noise due to lightning surge, etc. of an output element carries on output element voltage (Vs) wiring of an inverter IC in the motor apparatus containing the inverter circuit.

SOLUTION: The motor apparatus containing a printed board 1 which carries an inverter IC 4 or a pre-driver IC includes a series resistor 10 added between a Vcc DC power source 22 carrying a main board 2 and Vcc input terminal 5-26 of the inverter IC 4 of the printed board 1.
