The Motor Temperature Rise Test System Based on Magnetic Powder Dynamometer

Abstract

The motor temperature rise is an important indicator for the evaluation of motor performance and the development of motor testing system put forward higher requirements to data acquisition and processing. In view of this, the motor temperature rise test system based on the magnetic power dynamometer which acted as a load was studied. The overall structure and the software algorithm of the system were introduced. The existing synchronous sampling method was put into use in data acquisition system of the motor temperature rise test so that it can automatically test the motor temperature rise. Combining with the instance, proves the accuracy of this method. This method has the superiority of reducing errors and improving accuracy by combining with the instance.
