Electric Vehicle Motor Controller Design

Electric vehicles are using electric machines for propulsion and energy recuperation.

Electric vehicle motor controller design.

Electric cars are the future and are beginning to take off today. An electric motor converts electric energy into mechanical energy while an electric generator converts mechanical kinetic energy into electrical energy. 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. 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.

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. 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. This platform for motor control development is designed to deliver customized and production grade solutions for electric vehicle applications e taxi auto electric scooters electric four wheelers and more this platform has been designed to help you to achieve your business goals.

The tesla roadster nissan leaf. The controller s job in a dc electric car is easy to understand. An electric machine can be of two types. A 3 phase ac motor is the absolute standard for car companies when they make an electric vehicle.

The very simplest dc controller would be a big on off switch wired to the accelerator pedal. A motor controller with low cost and high current is a potential feature for particular electric vehicles. Let s assume that the battery pack contains 12 12 volt batteries wired in series to create 144 volts. The controller takes in 144 volts dc and delivers it to the motor in a controlled way.
