The armature will draw a very high current due to the small resistance of the armature winding to avoid this heavy starting current 4 Point starter is used. Here we are going to discuss the 4-point starter it’s working principle and construction Mainly two types of starters are used Working Principle of 4 Point Starter Four-point […]
A machine that converts DC power into mechanical power is known as DC motor. Dc motor has different types, dc motor has been used in industrial applications for years. Connecting with DC drive, dc motor provides very accurate control over it. DC motor can be used for conveyor, elevator application. In this article, we are […]
The term torque is meant turning or twisting movement of force about an axis. When dc machine is loaded either as dc motor or as a generator. the rotor conductors carry current, these conductors are in the magnetic field of the air gap. thus each rotor conductor experiences a force and torque developed in the […]
3 point starter is used for shunt and compound DC motor. it is called a three-point starter because it has three terminals named L, F, and A. The terminal named L must be connected to either side i.e the positive or negative side of the DC supply. Terminal A must be connected to the one of motor armature terminals and […]
