What AC motor is used in an escalator?
we can either use dc series motor or induction machine ,but dc supply is not easily available so we use induction motor ,
Which type of the motor is used in fan?
Low-power (a few watts) might use a synchronous motor, most fans use an induction motor. Above a couple of horse-power it might be a 3-phase induction motor.
Why using on motor star delta starter?
because at the starting the induction motor drawn a heavy current thats why we use starter to increase the starting resistance of the induction motor!
What types of motor used in water pump?
Depending upon the use, it can be a 3 phaze or 1 phaze induction motor. For domestic use it has to be a 1 phaze Induction motor but for industrial use it can be a 3 ph or 1 ph I.M.
What are the advantages of induction motor?
1. Induction motor has high starting torque, therefore use for operate pump which need high starting torque. 2. Induction motor operate on variable speed. 3. It can be used as generator when speed of motor is higher than synchronous speed.
How many Methods can be use to control the speed of Single Phase Induction Motor?
How many methods can be used to control the speed of Single Phase Induction Motor? 1.injecting emf method 2.by frequency control method 3.induced voltage method
Which size cable use for 37 kw induction motor?
To answer this question the voltage of the motor must be stated.
What type of motor is used in table fan?
Small house fans run on single-phase induction motors.
Why you use DOL starter in starting of motor?
because of starting current of induction motor is very high and it damages the insulation of motor
Why you use only single phase induction motor not other?
You would use a single-phase induction motor if the available electric power supply is a single-phase one. That applies to the average house or small business.
Why you use brushes for single phase induction motors?
There no brushes in an induction motor. The rotor is independent and is a short-circuited cage of parallel bars.
What are the advantages of single phase induction motor?
the torque requirement of single phase induction motor is less,and it is use for low power applications upto 1 to 10 kw.like in fans,mixiers
