Electric Motor Technology Comparison

An ac electric motor will not run when supplied with dc current and a dc motor will not run on ac current.

Electric motor technology comparison. The technology achieved a milestone when exro announced in december that in a partnership with electric bike manufacturer motorino after integrating exro s software and electric program module epm into the existing bike motor and powertrain the bike s top speed increased 25 and the low end torque also increased 25. Now a texas company is saying they ve developed a new electric motor technology that could increase performance while cutting costs in everything from electric cars to air conditioners. Turntide technologies is changing that. The srm electronic drive is characterized paired to the motor.

Comparison is tabulated for some parameters. Since the invention of electric motors two centuries ago progress in motor technology has been incremental. 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. Induction motor squirrel cage rotor induction motor slip ring rotor induction motor solid core rotor shaded pole motor.

Also characteristic graphs of different motors are included at some points. Nearly all motors in use today are driven by ac induction motors invented a century ago. 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. Different types of electric motors are compared on the basis of certain parameters which should be considered for selecting a particular motor type for electric vehicle application.

A switched reluctance motor srm is a brushless dc electric motor that provides continuous torque.
