Introduction

Equivalent circuit is widely used in inverter-driven induction motor speed control system, based on field-oriented control or other based on the model the realization of the type control algorithm requires the use of equivalent motor parameters to the motor. Suppliers and system engineers need to know their values, especially this is the case where the motor and frequency converter are supplied by different suppliers.

This standard provides a standardized test procedures to determine the parameters of the motor, while this standard provides an improved equivalent Way method. This test method can be operated in a laboratory capable of performing standard motor tests.

Note. The main purpose of this standard is to assist in the establishment of the corresponding model of the frequency control motor, so the simplified results can not be used to accurately determine the performance of the motor and efficiency.

Technical specifications IEC/T S60034-25 lists the motor parameters requirements, but their definition and determination methods are not included.
