How does an electric motor continue to turn?
The forces on each side of the coil are in the opposite directions to one another, so the coil turns (4). The commutator reverses the current around the coil with every half turn (5) meaning that the coil is pushed in the same direction every half turn, and thus continues to rotate (6).
Can a motor generate electricity?
You can use just about any motor to generate electric current, if it is wired correctly and you follow specific rules for its use. Modern AC induction motors are quite simple to wire as alternating current generators, and most will begin generating electricity the first time you use them.
What are the 6 parts of an electric motor?
These six components include:
- 1) The Rotor. The rotor is the moving part of your electric motor. …
- 3) The Bearings. The rotor in your electric motor is supported by bearings, which allow it to turn on its axis. …
- 4) The Windings. …
- 5) The Air Gap. …
- 6) The Commutator. …
- What Do All of These Components Have in Common?
How fast does an electric motor turn?
A 60 Hz power supply changes polarity 60 times per second, and a two-pole motor will spin at 3,600 rpm when connected to this source. A four-pole motor will only rotate at 1,800 rpm. For 50 Hz motors, the speed is 3,000 rpm with 2 poles, and 1,500 rpm with 4 poles.

What are 4 ways to increase the strength of an electric motor?
The speed of rotation of the coil can be increased by:
- increasing the size of the current;
- using a stronger magnet;
- increasing the number of turns of wire in the coil;
- reducing friction between the coil and the axel it rotates on.
Is electromagnet a permanent magnet?
Electromagnets: A permanent magnet is a magnet that retains its magnetion. A small permanent magnet can be used to hold notes onto the door of a refrigerator. … An electromagnet is a temporary magnet which magnetic field is produced by the flow of electric current in a coil wound round a soft iron core.
