| The driving system of electric motor has not only common properties of electric transmission, but also special application of electric motors. The electric motor runs on the land in the open air with close structure and completed operating modes. It is vehicle-bone waling machine. It must be fit for high speed running, frequent starting, braking, grade climbing, fast overtaking, emergent braking, severe conditions as snow, rain, hot, cold, salting after snow, and shaking on the road to ensure the comfort and safety of the drivers. The core of electric motor is to use electric system replace machine promotion system, use battery to replace petrol and reach all the performance and price index under zero exhaust or less exhaust. |
To meet the requirement, the company develops 4-14 seat electric seeing bar AC frequency conversion motor driving system to solve the core problems during running:
1、high torque under basic rate for fast starting, speed up, load grade climbing, and frequent start and stop
2、Low torque over basic rate, constant power, wide range for maximum speed, highway running and overtaking
3、Optimization of torque and speed to guarantee maximum running course after once charging
4、The motor and power control set has firm structure, small volume, light weight and are anti-shaking
5、Friendly operation performance, stable and comfortable, mature electric system fail protection means |
