Notes on Using Inverter for Motor

H

Using Inverter for Existing Standard Motor

When a standard motor is operated with this Inverter, a power loss is slightly higher than
when operated with a commercial power supply.

In addition, cooling effects also decline in the low-speed range, resulting in an increase
in the motor temperature. Therefore, motor torque should be reduced in the low speed
range.

The figure on the right-hand side shows allowable load characteristics of a standard
motor.

If 100% torque is continuously required in the low-speed range, use a special motor for
use with Inverters.

Allowable Load Characteristics of Standard Motor

25% ED (or 15 minutes)

40% ED (or 20 minutes)

60% ED (or 40 minutes)

Continuous

Frequency (Hz)

orque (%)

D

High-speed Operation

When using the motor at a high speed (60 Hz or more), note that problems may arise in
dynamic balance, bearing durability, and so on.

D

Torque Characteristics

When the motor is operated with the Inverter, torque characteristics differ from when
operated with a commercial power supply. Check the load torque characteristics of the
machine to be used with the motor.
