MOTOR INCORPORATING POWER CONVERTER, AND AIR CONDITIONER, WATER HEATER, AND VENTILATION BLOWER INCORPORATING THE MOTOR

摘要

A motor incorporating a power converter including a printed board on which a semiconductor module (an inverter IC), which converts a voltage of an external power supply into a high-frequency voltage and supplies the high-frequency voltage to a stator, is mounted, wherein a high-voltage circuit ground, which is a power ground of a high-voltage main circuit system of the inverter IC, and a low-voltage circuit ground, which is a ground of a control circuit system, which is a low-voltage circuit, of the semiconductor module, are provided on the board, and the high-voltage circuit ground and the low-voltage circuit ground are connected at one point via a resistor.
