Rotor (electric) The rotor is a moving component of an electromagnetic system in the electric motor, electric generator, or alternator. Its rotation is due to the interaction between the windings and magnetic fields which produces a torque around the rotor's axis.

Electric motors and generators A simple DC motor has a coil of wire that can rotate in a magnetic field. The current in the coil is supplied via two brushes that make moving contact with a split ring. The coil lies in a steady magnetic field. The forces exerted on the current-carrying wires create a torque on the coil.

Brake Rotors/Discs Replacement Service & Cost A brake rotor is a smooth metal disc attached to the wheel hub. Most new cars (1999 and above) come with rotors at each wheel. Older cars may have drums instead of rotors at the rear wheels. Brake rotors play an important part in the braking system.It is the friction between brake pads and rotors that cause your car to slow down and stop.our mechanic should measure the rotor thickness every time the brake pads are replaced. Brake rotors usually last twice as long as brake pads, which usually means you need to replace rotors every other brake service. If you drive the car with worn-out brake pads for too long, you will destroy the rotors.

induction motor a type of electric motor in which alternating current from a power source is fed through a primary winding and induces a current in a secondary winding, with the parts arranged so that the resulting magnetic field causes a movable rotor to rotate with respect to a fixed stator. Compare linear induction motor.

- Definition of Run winding: in an A/C electric motor the run winding is what keeps the motor spinning once it has started. Current flowing through this winding produces a rotating magnetic field in the stator that keeps the motor shaft turning after the start winding has turned off.

What is a torque motor â Principle Torque motor principle. Torque motors are a special class of brushless permanent-magnet synchronous motors. Since the payload is directly connected to the rotor without the use of transmission elements, torque motors are classified as direct drives. Depending on your perspective, a torque motor is either a rolled-up linear motor or a classic servodrive with a large number of poles.

- In a single phase electric motor, the centrifugal switch allows the start winding to be energized through the start capacitor when the motor is starting.his gives an out of phase magnetic field that, along with the in phase magnetic field from the run winding, helps the rotor to begin spinning. Once the rotor reaches a certain speed, the centrifugal switch changes state and cuts off the start winding.

Induction motor An induction motor or 3 phase induction motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor. An induction motor's rotor can be either wound type or squirrel-cage type. Three-phase squirrel-cage induction motors are widely used in industrial drives because they are rugged, reliable and economical.

- Lesson Summary. An electric motor is a device that turns electrical energy into motion, usually rotation. It changes electrical energy into mechanical or kinetic (movement) energy. This works using electromagnetism. A loop of wire containing a current is passed through an electromagnet's magnetic field.n electric motor contains a coil of wire (sometimes called a solenoid), that creates a magnetic field when electricity flows through it. This is collectively known as an electromagnet.

Difference Between Pump and Motor Electric motor, which is more commonly known as the motor, is a device that is capable of converting electrical energy into mechanical energy. Electric motors are divided into two categories based on the form of electricity on which it runs. These two types are DC motors and AC motors.
