Small make up today is to introduce the advanced nature of the brushless dc motor controller to know friends and see it! Electric vehicles is mainly used in urban traffic, most of the time in the working state of the start, acceleration, braking, so the starting performance of motor controller, accelerating performance, lower efficiency, at the time of braking energy regeneration, overload capacity of motor controller, the energy density of the motor controller, motor controller for electric vehicles is particularly important, reliability is one of the important indicators to measure electric vehicle motor controller. General motor controller to the maximum efficiency point of the design near the rated point, when the load deviation point, motor controller efficiency drops sharply, the affected the travel distance of the vehicle. Switched reluctance motor controller bigger torque when it is in low speed, but the efficiency is low, the permanent magnet synchronous motor controller with high efficiency, but low speed torque cannot ascend. Only the brushless dc motor controller has all the advantages of the above motor controller, it has a series dc motor controller, low-speed torque increase function, shunt dc motor speed control performance of controller, high efficiency characteristics of permanent magnet synchronous motor controller and close to the reliability of the asynchronous motor controller, very suitable for the need of electric vehicles.
