    > CM SERIES BRUSHLES CM series of low electric vehicle brushless DC motor controller

    CM series of low electric vehicle brushless DC motor controller


    Electric truck , electric forklift trucks, golf carts, electric high-speed motorcycles, electric sightseeing cars , electric tricycles, scooters and other low-voltage electric city car .

    Xi'an Chi Electric Drives and Controls Limited, the main products include two categories, the first category is the electric vehicles and high- voltage power supply for industrial use brushless DC motor controller CP, CI series, the power supply voltage is AC220V, AC380V and DC260V ~ DC600V, power 5.5KW ~ 75KW, overload factor 2 to 3 times. The second type is a low- voltage electric travel CM series brushless DC motor controller , power supply voltage is less than DC150V, power 2.5KW ~ 15KW, overload than 4 times.

    Product Features

    phase current control, start, acceleration , fierce acceleration, and other non-normal operation when running large current required to maintain the maximum phase current output, and will not appear instantaneous phase current overshoot , to ensure the safety of the controller , and reliable. Usually supply current ( also called the bus current ) limit and the methods of protection, can not control the phase current magnitude , phase current overshoot prone , damage the controller .

    electric vehicles , marine controller has more than four times the rated power overload .

    new multi- patented MOSFET parallel structure to solve the multi- MOSFET parallel mounting structure and process consistency , this structure and process to achieve the effect of heat quickly, loss, radiator area is reduced , the controller volume decreases . Patent No.ZL201020246979.8.

    Power unit upper and lower leg drive end direct interlock patented technology, solved due to interference caused by the upper and lower leg through the problems caused by damage to the controller . Patent No.301310114630.7 , utility model patent No.201320163004.2 .

    self-designed radiator and shell , with the appearance of patent , patent number: 201330098212.4 , the controller , small size, light weight, appearance, and ease of installation , cooling effect .

    compact internal structure, reducing the busbar stray inductance , higher reliability .

    complete protection, over-current , current limiting , undervoltage , stall , Hall fault protection.
