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.

Electric motor technology comparison.

Induction motor squirrel cage rotor induction motor slip ring rotor induction motor solid core rotor shaded pole motor. The srm is a viable replacement and improvement to induction motors in variable speed applications. 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. Together they form a very capable closely matched system.

Also characteristic graphs of different motors are included at some points. Since the invention of electric motors two centuries ago progress in motor technology has been incremental. A ac dc motor will however run on either ac or dc current. Turntide technologies is changing that.

A switched reluctance motor srm is a brushless dc electric motor that provides continuous torque. 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 srm electronic drive is characterized paired to the motor. An ac electric motor will not run when supplied with dc current and a dc motor will not run on ac current.

Nearly all motors in use today are driven by ac induction motors invented a century ago.
