- DC Series Motor.
- DC Shunt Motor.
- Cumulative Compound Motor.
- Three phase Synchronous Motor.
- Squirrel Cage Induction Motor.
- Double Squirrel Cage Motor.

What are motors used for in industry?
The largest electric motors are used for ship propulsion, pipeline compression and pumped-storage applications with ratings reaching 100 megawatts. Electric motors are found in industrial fans, blowers and pumps, machine tools, household appliances, power tools and disk drives.
Why motor starting current is high?
This high current in the rotor will create its own magnetic field which opposes the main stator magnetic field, this weakens the stator magnetic field so the back EMF in the stator will drop and the supply voltage will be much higher than the stator back EMF and so the supply current increases to a high value.
What defect is found in squirrel cage motor?
Squirrel cage induction motor cast rotor defect detection with magnetic field analysis.
Which electric motor is most widely used in high power applications?
What form of electric motor is most widely used in high-power applications? Stepper motors.
Which motors are widely used in industrial and commercial applications for precise angular movement?
As well as large industrial applications, servo motors are also used in small remote control models and robotics, with most servo motors being able to rotate up to about 180 degrees in both directions making them ideal for accurate angular positioning.
What is the difference between inrush current and starting current?
Inrush current or input surge current is the maximum amount of current drawn by the electrical device when it is turned ON for the first time. Electrical devices consuming alternating current,draws current several time greater than their full load current value at the instant of starting.
What is the of rotor faults occurring in induction motor out of total induction motor failures?
(d) Six turns of short circuit
| Turns | (A) | (A) |
|---|---|---|
| 0 | 2.886 | 2.877 |
| 1 | 2.967 | 2.890 |
| 3 | 3.187 | 2.885 |
| 6 | 3.609 | 2.882 |
What is an induction motor used for?
Used in almost every process, induction motors are mainly used in water pumps, kitchen appliances, fans and air conditioners, automobiles and common industrial machinery like boiler pumps and compressors.
Which motors are widely used in industrial and commercial application for precise angular moment?
Why induction motors are used in industry?
Three-phase squirrel-cage induction motors are widely used as industrial drives because they are self-starting, reliable and economical. Although traditionally used in fixed-speed service, induction motors are increasingly being used with variable-frequency drives (VFD) in variable-speed service.
What type of motors are used in industrial applications?
There are many types of motors used in industrial applications. The most common would probably be a DC motor, as the motor’s speed is easily controllable and well suited for production processes.
Why aren’t Stirling engines used more often?
So, why aren’t Stirling engines used more often? Here’s the Short Answer: Stirling engines are not good for applications that need to change their power output levels quickly, like cars for example. Stirling engines like to change their power output levels slowly.
What are the applications of permanent magnet DC motor?
The applications are- Wiper, Automatic windscreen, Drills, Conveyors, Fans, Boring mills, Shapers, Blowers, Spinning and weighing machine, Centrifugal pumps The permanent magnet DC motor is the special type of motor where we use a permanent magnet to create the required magnetic field.
Why BLDC motors are mostly used in EVs?
Why BLDC Motors is mostly used in EVs. 1. In comparison to ACIMs, BLDCMs are expensive to manufacture but are very efficient (85-90\%), lighter in weight, compact in size & Simpler to control the speed and reverse function than the ACIMs. 2.
