Get Price· Squirrel cage motors have been used in the auto shredder appliions, BUT the tons/KWH is less for a SCIM than for a WRIM, all things the same. Unless you have actually been to and worked in an auto/industrial scrap yard where the cars/busses, etc are sherdded from their present form to 'halfdollar size' in less than 10 seconds the true appreciation of the WRIM will never be appreciated.

Get PriceThe principal advantages of the squirrelcage induction motor are its simplicity of design and robust construction. Its torque/speed and current/speed characteristics are such that, on starting, a torque of typically twice fullload torque is produced but a large current (typically, six to eight times fullload current) is drawn from the supply. It is this latter aspect of the current drawn ...

Get Price· Squirrel cage induction motor started on full line voltage using D O L starter as a starting method draw very large starting current which can damage motor winding and also create a current surge on the power system. Hence another starting method is used to start three phase induction motor called an autotransformer starter. Auto transformer Starter can be used for both star/delta connected ...
Get PriceWhat is the principle of operation of squirrel cage induction motor? Squirrel induction motor working is based on the principle of electromagnetism. When the stator winding is supplied with a threephase AC, it produces a rotating magnetic field (RMF) which has a speed called synchronous speed. This RMF causes voltage induced in the rotor bars. What is the importance of end rings in squirrel ...
Get PriceThe squirrel cage type of rotor is shown below: In this type of rotor, the length is large while the diameter is small and is constructed with aluminium conductors thus weighs less. It is to be noted here that the torquespeed characteristics of a normal induction motor have both positive as well as negative slope regions that represent unstable and stable regions, respectively.

Get Price· Copper is better for something like a rock crusher where there can be a sudden change in load causing a torque shock that puts added stress on the rotor bars and end ring connections. You will find that most "crusher duty" motors will have copper rotor bars. You can use copper for anything as long as you accept the additional mass, but you should not use aluminum for shocks loads like crushers ...
Get Price1. Squirrel cage rotor 2.

Get PriceStandard types of squirrel cage motors are as explained below: (i) Class A (Normal starting torque, normal starting current, normal slip) Class A is the most popular type of squirrel cage induction motor. Motors of this type employ squirrel cage having relatively low resistance and reactance.
Get PriceStandard squirrel cage motors have a fixed value of starting and breakdown torque, whereas slip ring motor characteristics can be changed by adding or removing rotor resistance. Standard squirrel cage motors also have a fixed nominal rating that is almost always based on S1 duty. Slip ring motors can have many different ratings depending on the duty cycle for which they are specified. If the ...
Get PriceSquirrel cage motors operate at nearly constant speed, high over load capacity, and operates at better power factor. Some of disadvantages or demerits of squirrel cage induction motors are listed below: Main disadvantage of squirrel cage induction motor is that they have poor starting torque and high starting currents.
Get PriceStandard squirrel cage motors also have a fixed nominal rating that is almost always based on S1 duty. Slip ring motors can have many different ratings depending on the duty cycle for which they are specified.
