Equipment Introduction

Two basic requirements for frequency control:
1. Output power on the motor axis must be larger or equal to the required power of the operating equipment.
2. Electromagnetic torque produced by the motor must be larger or equal to the loaded resistance torque. (Which means that the output power of the inverter must be larger or equal to the rated power of the motor)-Maximum current principle.

Note: Same motor powers but different number of pole pairs, rated torque and rated current of motor are different.
