Electric Motors:
Motors are the driving force of industry or commercial facility.
An electric motor is a machine that converts electrical energy into mechanical energy. In normal motoring mode, most electric motors operate through the interaction between an electric motor’s magnetic field (Rotor) and winding currents(Stator) to generate force within the Motor.
The distance between stator and Rotor must be equal and balanced, and the force should be uniform.

Gearbox:
Gear is a toothed wheel with a mechanical method of transferring energy from one device to another. The gearbox is a system of gears which alters torque and speed between a drive and a driven system. They can also change the direction of the axis of rotation and can change rotary motion to linear motion.

Bearings:
The rotating shaft is to transmit power from one end to another, which need support to ensure stability and frictions less rotation.
The support for the shaft is known as “Bearings.”
The shaft has running fit in a bearing. All bearings are provided with a lubrication system to reduce friction between shaft and bearings.

Belts and Pulleys:
GA belt drive is one of the most cost-effective means of power transmission. The drive depends on the friction between the belt and the pulley to transmit power between drive and driven pulley. Belts are looped over pulleys and may have a twist between the pulleys, and the shafts need to be parallel.

Coupling:
It is a mechanical element used to connect two shafts of a transmission system and transmit the torque from one shaft to another.
Depending upon the coupling type, it can allow small misalignment and even its a flexible coupling, and it has no excuse for excessive misalignment.
Misalignment reduces the coupling life up to a great extent.
