Generators are appliances used for power supply when there is a power outage to ensure activities continue as usual. Generators are a secondary electric power source in both industrial and residential use. Are you interested to know more about the generator? Read it here weldinghubs. Generator components Engine The engine is regarded as the main … Read more
The Dot convention is a type of polarity marking for transformer windings which describes the phase relationships in the transformer schematic diagrams. In this, the dots are mentioned on the primary and secondary windings of the transformer. By convention, the dot represents the positive polarity. Before we learn dot convention in transformer, first see the … Read more
In previous articles, we discussed different types of single-phase induction motors such as Split phase induction motor, Capacitor-start inductor motor, Capacitor-start capacitor-run induction motor, and Shaded pole induction motor. In this article, we will see another type of single phase motor i.e. Permanent Split Capacitor Induction Motor. It is also known as Permanent Split Capacitor Motor or … Read more
A Capacitor Start Capacitor Run Induction Motor is a single phase motor consists of a stator and a single-cage rotor. The stator has two windings i.e. main winding and an auxiliary winding. The auxiliary winding is also known as starting winding. In construction, these two windings are placed 90° apart in space. This motor has … Read more
The 1-Phase and 3-Phase Induction Motor is compared based on the factors such as power factor, efficiency, maintenance, supply, starting torque, applications, etc. Features 1-Phase Induction Motor 3-Phase Induction Motor Supply Works on 1-phase supply Works on 3-phase supply Starting torque Low High Power factor Low High Efficiency Less High Maintenance They are easy to … Read more

Shaded Pole Induction Motor is a type of single-phase motor consists of a stator and a cage-type rotor. It is a self-starting motor. It is also called as Shaded Pole Motor. Definition Shaded pole motor is a salient-pole, split phase type, squirrel cage rotor single phase induction motor provided with one or more auxiliary short-circuited … Read more
Since synchronous motors are not self-starting inherently, we should have some means of starting synchronous motors. The methods are given below: 1. Induction Motor Start Damper windings, consisting of copper bronze bars embedded in slots in the pole faces and short-circuited at both ends are usually provided in synchronous motors which serve not only to … Read more
In this article, we will see the difference between Single Cage & Double Cage Induction Motors. Single Cage Double Cage 1. Starting performance As compare to double cage rotor, the single cage has less starting torque so at starting less heating loss occur. A double cage motor develops higher starting torque for low starting current and … Read more
