Appendix 3 : Motor selection reminder
Standard Motor
Please pay attention to the following when using inverter to drive
standard motor(3 phase induction motor) :
1. When using inverter to drive standard motor, its power loss is
higher than using commercial power.
2. When standard motor running at low speed and cooling fan
running at low speed then motor running temperature will be
rised. So, inverter should NOT running at low speed for a long
time except using compulsory cooling inverter motor.
3. When standard motor running at low speed, motor output
torque will drop. So, please reduce overloading usage.
4. The following is standard motor overloading permissive dia-
