A cage rotor motor, or squirrel cage motor, is ideal for conveyor belts due to its robust design, reliability, and low maintenance requirements. Its simple construction allows for efficient operation and high starting torque, which is beneficial for handling heavy loads. Additionally, these motors are energy-efficient and can operate well in various environmental conditions, making them a practical choice for continuous material handling applications.

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.
Standard induction motor has a closed squirrel cage rotor, where as open ended induction motor has split phase rotor.

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.

to obtain high starting torque
The starting torque of a wound-rotor motor is higher per ampere of starting current than that of a squirrel cage motor due to the ability to control the rotor resistance. In a wound-rotor motor, external resistance can be added to the rotor circuit, allowing for increased torque production during startup without drawing excessive current. In contrast, squirrel cage motors have a fixed rotor resistance, which limits their starting torque and results in a relatively lower torque per ampere of starting current. This design feature enables wound-rotor motors to provide better performance in high-torque applications.
The formula to calculate the rotor speed (N_r) of a cage rotor induction motor is given by: N_r = (120 * f) / P, where f is the supply frequency in Hz and P is the number of poles in the motor. This formula assumes the motor is running at near synchronous speed and neglects slip.
End rings or rotor conductors are fitted to the rotor of a squirrel cage motor to facilitate the flow of current and create a magnetic field necessary for the motor's operation. They connect the individual rotor bars at both ends, forming a closed circuit that allows the induced currents to circulate effectively. This design enhances the efficiency and performance of the motor by enabling it to generate torque and maintain rotational speed under varying load conditions. Additionally, it helps in minimizing electrical losses and improving the overall reliability of the motor.
although this is not a chemistry question I do have an answer for you. A motor with copper bars is classified as a shaded pole motor. They are low torque motors and do not require any capacitors for run or start functions. hope that helped
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.
