Brushless DC motor test system (BLDC)

The End-of-line (EOL) Brushless DC (BLDC) Motor Test System is used for assessing the performance and performing quality analysis of 2-wire, 3-wire, 6-wire, 8-wire, and 9-wire BLDC motors ranging from 6 V to 48 V. The system is capable of testing motors running as high as 40,000 RPM in real time.

The system measures various parameters, such as, torque, torque constant, speed, current, voltage, resistance, inductance, back EMF, thermistor voltage, enable/disable logic, direction of rotation, etc. Additional parameters can be measured as per the customer’s requirements.

The End-of-line (EOL) Brushless DC (BLDC) Motor Test System makes use of an electronically-controlled brake, optical encoder and reaction torque sensor/load cell arrangement. It has a reliable and robust production-class hardware for accurately measuring various parameters by performing a number of tests sequentially. The 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 End-of-line (EOL) Brushless DC (BLDC) Motor Test System consists of a proprietary test software. Test parameters related to a large variety of BLDC Motors can be pre-programmed using a PC and stored in the memory and relevant parameters can be loaded when testing a motor of a particular type and rating. 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.
