Electric motors convert electric current at a torque. They are the most common electromechanical drives in cars and trucks. In almost every pump, fan and drive in the car, an electric motor is used. A typical car has about 25 electric motors and this number is growing with each new model year. Luxurious vehicles can have more than 100 engines. These engines cover a wide range of size and power. From tiny step engines that set the position of indicators in “analog” measuring devices (working on millivatts) to a starter in cars with internal combustion engines (kilowatts) or electric drives in electric or hybrid electric vehicles (hundreds of kilowatts).
