Most Efficient Electric Motor Type

Overview of motor types.

Most efficient electric motor type.

One little hydrogen fuel cell vehicle holds the guinness world record for the most efficient vehicle and uses a slotless brushless 60l h 175 a from koford motors to drive its rear power wheel. This article takes a look under the hood and gives an overview of the most commonly used ev motor types. Generally dc compound motor is a hybrid component of dc series and shunt motors. In this type of electric motor the stator and rotor can be connected to each other through a series shunt windings compound.

Evs use traction motors that are capable of delivering torque to the wheels. Electric motors can be powered by direct current dc sources such as from batteries motor vehicles. Yucca on february 26 2009 09 28 01 pm 33 efficient thatâ s really bad efficiency especially at zero kelvin lol. The motor efficiency map that is its efficiency as a function of torque and speed determines the energy consumption for consumer vehicles and the peak power characteristics are an.

Evs operate via an electric motor powered by battery energy. An electric motor is an electrical machine that converts electrical energy into mechanical energy most electric motors operate through the interaction between the motor s magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor s shaft. This year the tiny car from the duke electric vehicles team beat the 12 600 mpg efficiency of the pac car 2 in turn designed by a student team at the eidgenössische technische hochschule eth in.
