Motor
Motors are powerful and amazing. Now that I took ECE106 and ECE140, I have a much better understanding to understand how motors work.

Basics of Motors
Notes from
Motor
An electric motor is a device converting electrical energy into mechanical energy (generally a torque).
This conversion is usually obtained through the generation of a Magnetic Field by means of a Current flowing into one or more coils.
The specific relationship between current and magnetic
The rotation is obtained thanks to the attractive force between two magnetic fields:
- One field is located on the rotor (the moving part)
- The second magnetic field is located on the stator (the body of the motor)
Usually one of the two is generated by a permanent magnet while the other one is generated through an electromagnet (solenoid).
For example, look at this Brushed DC Motor:
Categories of motors
We can divide Motors divide in 2 main types
- Synchronous Motor
- Asynchronous Motor (Induction Motor)
