An electric motor is a device which converts electrical energy to mechanical power by using an electro-motive force. A typical electric motor operates by the interaction of the magnetic field of an electromagnet and the electrical current in a conductor winding to produce force in the form of mechanical torque applied to the motor shaft.
There are many different types of motors. One such type is the reciprocating motor. The term “revolving” has been coined from the fact that when the rotor is turned, a current is generated which goes the other way and is then turned back to its original position.
The other most common type of motor is the DC alternator, an alternating current motor. This type of motor is used for powering small machines such as hand drills and lawnmowers.
Another motor type is the generator motor. This motor uses a battery to store power. In some applications, the output voltage of the generator motor can be used to provide electric energy to appliances and other devices. A similar type of power supply is called the wind turbine.
Motor efficiency is dependent upon the size, the speed, and the power of the motor. The higher the speed and the power of the motor, the more efficient it will be. Also, the more energy the motor can generate, the less weight it has. This is why small engines are preferred for small vehicles or for boats.
The motor may also be referred to as a generator because it is a component which converts electrical power into mechanical force. Many kinds of motors exist and are used in different applications.
Permanent magnet motor uses a permanent magnet to create a magnetic field which drives the rotor. These motors are used in space vehicles.
A permanent magnet motor has one main pole and one magnet on one side. There are two magnets on the opposite sides which are attracted to one another and cause the motor to rotate. The speed of the motor depends on the size of the motor.
Wind engines are used to move air, water or steam through a pipe. This type of engine works by turning a rotary wheel which turns a shaft to turn a propeller. The rotation and speed are produced by an external magnetic force which is used to turn the motor.
Motor drives air compressors, which are used to move a pressurized gas, to move through the piping system. They are more efficient and lower in cost than traditional compressors.
