Universal Motor Test System

Universal Motor Test System is used for assessing the performance and performing quality analysis on universal motors. The system measures various parameters, such as, torque, speed, acceleration, current, voltage, direction of rotation, etc. Additional parameters can be measured as per the customer’s requirements.

It makes use of an electronically controlled brake, optical encoder and reaction torque sensor/load cell arrangement. The selection of measurement components is done keeping in mind the high RPM and low torque nature of universal motors.

The Universal Motor Test System makes use of a reliable and robust production-class hardware for accurately measuring various parameters by performing a number of tests sequentially. The AC and DC drives required for the driving mechanics are fully configurable and customizable and are included in the measuring hardware. A precision machined mechanical fixture is used for securing motors of various frame sizes to have minimal axial misalignments with the measuring hardware.

The Universal Motor Test System consists of a proprietary test software. All measurements are made by the system according to the parameters selected by the user in the software and the test results are displayed in the software for evaluation.
