Encoder Test System
The Motor Encoder Test System is primarily useful for assessing the performance and performing quality analysis for Encoders mounted on Miniature High Performance Brushed PMDC motors. It makes use of a reliable and robust, production-class, embedded hardware for accurately measuring various electrical and physical parameters of encoder performance by performing a number of tests. The test system is also equipped to program MR-type sine/cosine encoder IC by using a serial EEPROM. It can also checks the major parameters of the tachometer, if fitted on the motor. All measurements are made by the system according to the test conditions selected by the user and the test results are sent to a PC for evaluation. The Motor Encoder Test System makes use of a powerful multi-processor logic, as functionality and speed of measurement is essential to check Motor and Encoder parameters in real time.
