What type of rotor is found in a universal motor?
Wound rotor and squirrel-cage rotor
What are the starting currents for a single cage rotor motor?
gagy
Why squirrel cage motor is NOT suitable for use as a DC machine?
A 'squirrel cage' rotor is used in an a.c. inductionmotor, meaning that there is no electrical supply to that rotor with the currents in the rotor , instead, being the result of induced voltages caused by currents flowing in the field windings. A rotor of a d.c. motor, is electrically connected to the supply. The two types of motor work on completely different principles, so cannot use a squirrel cage rotor.
What is the useful of open end winding of induction motor?
Standard induction motor has a closed squirrel cage rotor, where as open ended induction motor has split phase rotor.
Which motor doesn't have any winding on its rotor?
Squirrel cage induction motors.

What is squirrel cage induction generator?
Squirrel cage type is a type of Induction motor. It tells that the rotor is "squirrel cage" type. Another type of induction motor is with "slip ring" type of rotor. Squirrel cage type is most widely used Induction motor.
Which motor doesn't have any winding on its rotor?
Squirrel cage induction motors.
What is the use of double cage rotor in induction motor?
to obtain high starting torque
What is squirrel cage in motors?
When the number of rotor and stator poles are equal in the motor and if these rotor poles have opposite polarity with respect to the stator poles magnetic locking occurs. This magnetic locking is know as "Cogging" in 3 phase squirrel cage induction motor. In order to avoid this problem, the rotor slots housing the conductors are skewed by an angle of 5 degrees over the surface.
How do you increase starting torque in cage type 3-phase induction motor's?
by adding external resistance to the shaft of rotor
Where would a squirrel cage motor be used?
The configuration of the rotor resembles the exercise wheel found in a squirrel cage. There is also a 'squirrel cage fan' that also is named for the resemblance.
What happen if fan not run in squirrel cage induction motor?
The fan mounted on the shaft is for cooling of the stator and rotor. If the fan stops the motor gets overheated and burns out.
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.
