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.
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
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.
