How is electrical energy converted into mechanical energy to do work?
The tool to convert electrical energy into mechanical energy is a motor. A rotary machine converts electrical energy into mechanical energy. It mainly includes an electromagnet winding or a distributed stator winding used to generate a magnetic field and a rotating armature or rotor. The current in the wire passes through and is rotated by the magnetic field
