A three phase induction motor is a type of electric motor widely used for various industrial and commercial applications. It operates based on the principles of electromagnetic induction, where a rotating magnetic field is generated in the motor, causing the rotor (the moving part of the motor) to rotate. Three-phase induction motors are efficient, reliable, …
A sleeve bearing, also known as a plain bearing, is a type of bearing that is used to reduce friction and support rotating or sliding shafts within machinery. It consists of a cylindrical metal sleeve or bushing that provides a smooth and low-friction surface for the shaft to rotate or slide against. Sleeve bearings are …
