Electric Vehicle Motor Controller Design

A brushless dc electric motor bldc motor or bl motor also known as electronically commutated motor ecm or ec motor and synchronous dc motors are synchronous motors powered by direct current dc electricity via an inverter or switching power supply which produces electricity in the form of alternating current ac to drive each phase of the motor via a closed loop controller.

Electric vehicle motor controller design.

Electric vehicles are not something new to this world but with the technological advancement and increased concern on controlling pollution has given it a tag of future mobility. The controller takes in 144 volts dc and delivers it to the motor in a controlled way. However they are still pretty expensive. A motor controller with low cost and high current is a potential feature for particular electric vehicles.

Itri has already developed 5 15kw controller and integrated in carrying cargo. The tesla roadster nissan leaf. 200kw ac motor controller for electric car. As well as implementation of hardware and software design it passes the few environmental tests to demonstrate reliability.

Electric vehicles are using electric machines for propulsion and energy recuperation. Electric cars are the future and are beginning to take off today. Compared to an internal combustion engine an electric motor has several advantages. The core element of the ev apart from electric vehicle batteries which replaces the internal combustion engines is an electric motor the rapid development in the field of power electronics and control techniques.

The controller s job in a dc electric car is easy to understand. An electric motor converts electric energy into mechanical energy while an electric generator converts mechanical kinetic energy into electrical energy. A 3 phase ac motor is the absolute standard for car companies when they make an electric vehicle. An electric machine can be of two types.
