The Motor Winding Resistance Tester measures the resistance of each rotor winding of permanent magnet DC (PMDC) motors. The system automatically measures the resistance of each winding in a sequence and compares the results with the preset limits to decide the Pass-Fail criteria of the motor. It can perform tests in Loop Mode or Cross Mode. It is a universal test system, capable of testing any motor having up to 13 windings. The system is supplied with a custom test fixture that helps to perform the tests and maintain test integrity.
Measurements & Controlled Parameters
- Kelvin’s 4-wire principle of resistance measurement. Rotor resistance as low as 0.1 ohm can be measured with an accuracy of 5%
- Control of test multiplexer for sequential selection of windings
- PLC and HMI based system
- Custom designed test fixture that is suitable for motors of various shapes and sizes.
