Electric Motors

Supplier of Electric Motors in Pakistan:

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor’s magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor’s shaft. An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy.
Electric motors can be powered by direct current (DC) sources, such as from batteries, or rectifiers, or by alternating current (AC) sources, such as a power grid, inverters or electrical generators.
Electric motors may be classified by considerations such as power source type, construction, application and type of motion output. They can be powered by AC or DC, be brushed or brushless, single-phase, two-phase, or three-phase, axial or radial flux, and may be air-cooled or liquid-cooled.

Rotor:

The rotor in an electric motor is the moving part, and the main function of this is to rotate the shaft for generating the mechanical power. Generally, the rotor includes conductors which are laid to carry currents, and communicate with the magnetic field in the stator.

Bearings:

The bearings in the motor mainly give support to the rotor to activate its axis. The shaft of the motor expands with the help of the bearings to the load of the motor. As the load forces are used outside of the bearing, then the load is known as overhung.

Stator:

The stator in the motor is the inactive part of the electromagnetic circuit. It includes permanent magnets or windings. The stator can be built with different thin metal sheets which are known as laminations. These are mainly used for reducing energy losses.
