Advantages of Squirrel Cage Motor

Closed box structure

The high voltage squirrel cage motor adopts a closed box structure, which can effectively prevent dust, water vapor and other external impurities from entering the motor and ensure the stable operation of the motor.

Accurate temperature monitoring

The stator windings and bearings of the high voltage squirrel cage motor are equipped with temperature measuring elements pt100, six in total with two windings per phase and one bearing at each end. The elements are connected to a separate junction box, and the temperature rise is monitored in real time through the monitoring system.

Efficient moisture-proof measures

The high voltage squirrel cage motor is equipped with a moisture-proof heater, which is used when the machine is shut down to increase the internal temperature, dissipate moisture, and reduce the risk of failure caused by moisture.

Types of Squirrel Cage Motor

A: This is the most popular and used type of Squirrel Cage Induction Motor. They are widely used in machine tools , fans , etc. They have normal starting toque, low resistance, slip and higher efficiency at full load.

B: They operate at high reactance and can be easily replaced with the Class A type for the new installations and requirements , especially when reduced starting voltage is needed.

C: These type have low starting current and high starting torque and have low starting current characteristics , they are also called as double cage motors.

D: These motors have high resistance and also have high starting torque and low starting current , and a large amount of slip at full load . Common applications for these type of motors are bulldozers, shears , etc. They have low operating efficiency and the high rotor resistance makes these motors strong.

E: These motors operating at normal starting current and low starting torque , normal starting current and have low slip at rated load. They require compensator because starting current is high for the motors above 5 kW ratings.

F: These motors operate at low starting current and low starting torque and at normal slip. They maintain a constant speed , self starting and require low maintenance. Most commonly used in centrifugal pumps.

Application of Squirrel Cage Motor

Industrial field

High voltage squirrel cage motor is widely used in the industrial field, mainly used to drive various heavy machinery and equipment, such as compressors, pumps and large fans.

Transportation field

In the transportation field, high voltage squirrel cage motor is mainly used in the power system of electric vehicles, electric trains and other transportation tools.

Agricultural field

In the agricultural field, high voltage squirrel cage motor is widely used in irrigation equipment, agricultural machinery and greenhouse ventilation systems.

Energy field

In the energy field, high voltage squirrel cage motor is often used in auxiliary equipment of wind power generation and hydropower stations, such as water pumps and fans.

Squirrel Cage Motor Construction

Stator

It consists of a 3 phase winding with a core and metal housing. Windings are such placed that they are electrically and mechanically 120o apart from in space. The winding is mounted on the laminated iron core to provide low reluctance path for generated flux by AC currents.

Rotor

It is the part of the motor which will be in a rotation to give mechanical output for a given amount of electrical energy. The rated output of the motor is mentioned on the nameplate in horsepower. It consists of a shaft, short-circuited copper/aluminum bars, and a core.

Fan

A fan is attached to the back side of the rotor to provide heat exchange, and hence it maintains the temperature of the motor under a limit.

Bearings

Bearings are provided as the base for rotor motion, and the bearings keep the smooth rotation of the motor.

FAQ

Q: What is a squirrel cage on a motor?

A: A squirrel-cage rotor is the rotating part of the common squirrel-cage induction motor. It consists of a cylinder of steel laminations, with aluminum or copper conductors cast in its surface.

Q: What is the difference between a squirrel cage motor and an induction motor?

A: They are widely used in industrial and household applications because they are simple, reliable, and efficient. The main difference between a squirrel cage motor and other types of induction motors is the construction of the rotor.

Q: Is a squirrel cage motor 3 phase?

A: 3 phase squirrel cage Induction Motor is one of the most popular types of AC electric motor which achieve the electromechanical energy conversion through stator and squirrel cage rotor by electromagnetic induction. That's why it's called squirrel cage induction motor.

Q: When would you use a squirrel cage motor?

A: Squirrel cage motors are often used to drive fans and blowers in HVAC systems, as well as in exhaust fans, portable fans, and other types of ventilation equipment.

Q: Is a squirrel cage motor self-starting?

A: Self-starting - three-phase induction motors are inherently self-starting i.e. providing electrical current is supplied to the stator windings, the motor will rotate, no other external force is required.

Q: What is the difference between a slip ring and a squirrel cage motor?

A: The major difference between them is that the slip ring's motor comes with an external circuit that controls the speed of a motor.
