Squirrel cage motors are a subclass of induction motors, which harness electromagnetism to generate motion. They are so-called “squirrel cage” motors because the shape of their rotor – the inner component connected to the output shaft – looks like a cage.
What is the purpose of a squirrel cage motor?
Squirrel cage induction motors are commonly used in many industrial applications. They are particularly suited for applications where the motor must maintain a constant speed, be self-starting, or there is a desire for low maintenance. These motors are commonly used in: Centrifugal pumps.
How do I know if I have a squirrel cage induction motor?
Classification of Squirrel Cage Induction MotorClass-A Design. These type motors have low resistance, reactance, slip, and higher efficiency at full load. ... Class B Design. These motors have high reactance and operate 5-150KW range. ... Class C Design. ... Class D Design. ... Class E Design. ... Class F Design.
Why are squirrel cage motors so reliable?
Squirrel cage motors are explosion proof due to the absence of brushes slip rings and brushes which eliminates the risks of sparking. Squirrel Cage motors are better cooled compared to slip ring induction motors.
Is a squirrel cage motor AC or DC?
Squirrel cage motors maximize electromagnetic induction by utilizing rotor bars to interact with the stator's EMF. The stator usually contains windings of wire which carry an AC current; this current changes in sync with a sinusoidal curve (or “alternates”), which changes the current direction in the wire windings.

What is difference between squirrel cage and induction motor?
Slip ring induction motors are mainly used in applications where high starting torque is required such as cranes, hoists, conveyors, etc. while the squirrel cage induction motors are used in general application like lath machine, drill machine, pumps and fans, etc.
What is the difference between induction motor and squirrel cage motor?
Slip ring induction motors are mainly used in applications where high starting torque is required such as cranes, hoists, conveyors, etc. while the squirrel cage induction motors are used in general application like lath machine, drill machine, pumps and fans, etc.
What are the characteristics of induction motor squirrel cage type?
They are low cost. Require less maintenance (as there are no slip rings or brushes) Good speed regulation (they are able to maintain a constant speed) High efficiency in converting electrical energy to mechanical energy (while running, not during startup)
What is the difference between squirrel cage and wound rotor induction motor?
The major difference is the external resistance circuit for controlling the speed of the motor. In the case of squirrel cage induction motor, rotor bars are short-circuited with end rings. Therefore, the external resistance cannot connect with the rotor.
How do I know if I have a slip ring motor?
The windings are connected to external resistance through slip rings, which helps to control the torque/speed of a motor....Difference Between Squirrel Cage and Slip Ring Induction Motor.Slip Ring MotorSquirrel Cage MotorStarting torque is highTorque is lowEfficiency is lowEfficiency is high4 more rows

· What is Squirrel Cage Induction Motor. A 3 phase squirrel cage induction motor is a type of three phase induction motor which functions based on the principle of electromagnetism.It is called a ‘squirrel cage’ motor because the rotor inside of it – known as a ‘squirrel cage rotor’ – looks like a squirrel cage.

An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor. An induction motor's rotor can be either wound type or squirrel …

The animation at right represents a squirrel cage motor. The squirrel cage has (in this simplified geometry, anyhow!) two circular conductors joined by several straight bars. Any two bars and the arcs that join them form a coil – as indicated by the blue dashes in the animation. (Only two of the many possible circuits have been shown, for ...
