Electric Vehicle Motor Controller Design

The very simplest dc controller would be a big on off switch wired to the accelerator pedal.

Electric vehicle motor controller design.

An electric motor converts electric energy into mechanical energy while an electric generator converts mechanical kinetic energy into electrical energy. Electric vehicles are using electric machines for propulsion and energy recuperation. The tesla roadster nissan leaf. 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 3 phase ac motor is the absolute standard for car companies when they make an electric vehicle. Let s assume that the battery pack contains 12 12 volt batteries wired in series to create 144 volts. As well as implementation of hardware and software design it passes the few environmental tests to demonstrate reliability. Electric cars are the future and are beginning to take off today.

An electric machine can be of two types. However they are still pretty expensive. The controller takes in 144 volts dc and delivers it to the motor in a controlled way. Itri has already developed 5 15kw controller and integrated in carrying cargo.

The controller s job in a dc electric car is easy to understand. 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. 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. A motor controller with low cost and high current is a potential feature for particular electric vehicles.
