Motor Test Application Introduction

The MTP - EDU series DC test power supply is specially developed for the test of drive motor system production line; it can be equipped with built-in energy discharging unit to meet the instantaneous energy consumption generated during the various motor tests.
It adopts full-bridge phase-shifting soft switching technology and double closed-loop control circuit to feature the power supply with high output accuracy, high efficiency and reliable working ability.
Presently, the MTP series are suitable for two main motor tests below:
1. Motor finished product test
The DC test power supply can simulate the output characteristics of the power battery to supply power to the motor drive system and assist in completing the factory test on various index of the finished product. Including motor drive system working voltage range, stalled test and maximum working speed test etc.

Product Application Solutions 1 Matching Dynamometer Bench
2. Motor type test
The DC test power supply can be embedded into the motor test bench system to form a motor test bench. Such as dynamometer test bench or dual-motor drag test bench.
Product Application Solution 1 Motor Pairing Test
