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).
Electric motors in cars
There are several types of engines, including:
AC electric motors in cars can be single -phase or three -phase. Since the power source in the car, as a rule, is a direct current source (for example, a battery), engines that do not require a certain type of inverter to change the power power in a constant form suitable for the electric motor movement. Engines having a controller that uses feedback from position sensors to fix the angle of the rotor are called server.
