Solution

Motor stator electric heating test system

Advanced technology

This solution adopts advanced SVPWM control technology to achieve high-precision control of sinusoidal AC current, quickly and evenly heat the stator winding and core, and the control device has a complete diagnosis and protection mechanism.

System Features

● The stator heating AC current is set by DC/AC converter;

● Different current values ​​and frequencies can be set according to heating time requirements;

● Automatically identify the maximum allowable heating current value of different stators;

● Automatically detect the DC impedance of the stator winding to determine whether the winding temperature reaches the preset value;

● Realize the real-time sampling resistance function through the sampling circuit;

● It has over-current, short-circuit, over-voltage, under-voltage, over-temperature protection and automatic shutdown functions.
