Electric Vehicle Motor Design

Bldc motors are suitable for high power density design approach.

Electric vehicle motor design. While there are a number of ways to do this including keeping the clutch and machining the flywheel i chose to keep it simple and use a lovejoy style connector. An electric machine can be of two types. An electric vehicle ev is a vehicle that uses one or more electric motors or traction motors for propulsion. Gm s new electric drive module in the 2014 spark ev features a gm designed and manufactured 120 kw permanent magnet traction motor visible on the left side and smart use of key carryover components from volt and the two mode hybrid transmission.

An electric motor converts electric energy into mechanical energy while an electric generator converts mechanical kinetic energy into electrical energy. The all electric vehicle lost because of the lack of range from current battery technology. The coupler is a means of connecting the rotary power of the electric motor to the transmission to power the car. Bldc motors further have two types.

Consider for one thing that most carmakers have brought motor manufacturing in house. The invention of the first model electric predecessor vehicle is attributed to various people. This is a novel dc motor generator for electric vehicles marine and aerospace applications. In 1828 the hungarian ányos jedlik invented an early type of electric motor and created a small model car powered by his new motor.

Bldc motors have traction characteristics like high starting torque high efficiency around 95 98 etc. An electric motor and battery power can provide the majority of the population an all electric commuter car for under 10 000. While the electric motor has its own century of progress under its belt there s still much that can be done. During the infancy of the automobile electric and gasoline vehicles competed for dominance of the market.

Design and function basics of electric cars step by step for engineers when the electric motor generator is driven mechanically it supplies electrical energy as an alternator. Electric motors generators used for propulsion are water cooled. Ev design electric motors electric vehicles are using electric machines for propulsion and energy recuperation. An electric vehicle may be powered through a collector system by electricity from off vehicle sources or may be self contained with a battery solar panels fuel cells or an electric generator to convert fuel to electricity.

Until recently the. When the electric motor generator is supplied with an electrical current it works as a drive.
