VFD is a short form of a variable frequency drive also called Frequency converters, which has undergone extremely rapid changes, largely as a result of the development of microprocessor and semiconductor devices and their reduction in prices. However, the basic…
Why single-phase induction motor is not self-starting? Single-phase induction motor Starting winding to make self starting A single phase induction motor is very similar to a three phase squirrel cage induction motor except for single-phase motor, not self-starting.It has (i) a squirrel-cage rotor as to a…
Winding insulation resistance checking of three-phase / single phase Motor The motor is mostly used machine to drive loads in the industry, for pumping, elevators, and conveyor belts. so its reliability must be maintained, for the long life of the…
Types of insulation classes used in electrical motor/ transformer There are three main categories of insulating materials, gases, liquids, and solids. The types of insulating materials are classified mainly based on thermal capability. types of insulation classes for electric motors…
Single-phase salient pole synchronous motors are called reluctance motors. the stator of the reluctance motor has the main winding and the auxiliary winding the same as the single-phase induction motor. The motor starts as an induction motor. It is pulled…
A Slip Ring Induction Motor is a type of asynchronous induction motor. Slip ring induction motors rotor is wound identically to the stator and is connected through rotating electrical contacts known as slip rings. These slip rings let the induction…
While selecting an induction motor, Motor Duty Cycle must be considered to meet the induction motor application requirement. The duty types are indicated on motor nameplate data by S1, S2… In the absence of an indication of the rated duty…
The three-phase induction motor is one of the most widely used motors in various industrial applications. Its robust construction, simplicity, and versatile nature make it a preferred choice for powering machinery and equipment. In this article, we will delve into…
