Electric Vehicle Motor Efficiency

The bldc motors are the most preferred motors for the electric vehicle application due to its traction characteristics.

Electric vehicle motor efficiency.

Traction motor and energy conversion efficiency. This motor is the king of electric car motors. An electric motor typically is between 85 and 90 efficient. That means it converts that percentage of the electricity provided to it into useful work.

You ve no doubt heard about this famous characteristic of electric cars. An electric vehicle ev starts with a huge advantage over an internal combustion engine ice vehicle. Bldc motors further have two types. Ice vehicles generally run at about 20 efficiency meaning that 80 of the energy content of their fuel is wasted versus evs which put about 80 of their input energy into turning the wheels.

Motor efficiency is the most important factor to consider in the development of implantable devices such as ventricular assist devices vads and total artificial hearts tahs. Bldc motors have traction characteristics like high starting torque high efficiency around 95 98 etc. Bldc motors are suitable for high power density design approach. Evs convert over 77 of the electrical energy from the grid to power at the wheels.

The power of a vehicle s electric motor as in other vehicles is measured in kilowatts kw. 100 kw is roughly equal to 134 horsepower but electric motors can deliver their maximum torque over a wide rpm range. All the torque is available from a standstill. The electric energy that is input into the device is converted to mechanical energy by the motor.

The electric drag racers burn a lot of tire rubber with this motor and if laying down long black tracks and clouds of smoke is your thing this is the motor you want. Conventional gasoline vehicles only convert about 12 30 of the energy stored in gasoline to power at the wheels.
