    Using the Inverter for a Motor Chapter 11 H Using Inverter for Existing Standard Motor When a standard motor is operated with the Inverter, a power loss is lightly higher than when operated with a commercial power supply. In addition, cooling effects also decline the low-speed range, resulting in an increase in the motor temperature.

    Using the Inverter for a Motor Chapter 11 D Vibration The 3G3MV Series employs high carrier PWM control to reduce motor vibration. When the motor is operated with the Inverter, motor vibration is almost the same as when oper- ated with a commercial power supply. Motor vibration may, however, become greater in the following cases.

    Using the Inverter for a Motor Chapter 11 H Using Inverter for Existing Standard Motor When a standard motor is operated with the Inverter, a power loss is lightly higher than when operated with a commercial power supply. In addition, cooling effects also decline the low-speed range, resulting in an increase in the motor temperature.

    Using the Inverter for a Motor Chapter 11 D Vibration The 3G3MV Series employs high carrier PWM control to reduce motor vibration. When the motor is operated with the Inverter, motor vibration is almost the same as when oper- ated with a commercial power supply. Motor vibration may, however, become greater in the following cases.

    Using the Inverter for a Motor Chapter 11 D Gearmotor The speed range for continuous operation differs according to the lubrication method and motor manufacturer. In particular, the continuous operation of an oil-lubricated motor in the low speed range may result in burning. If the motor is to be operated at a speed higher than 60 Hz, consult with the manufacturer.
