Squirrel cage induction motor

Squirrel cage induction motor is a common type of electric motor that is commonly used in a variety of applications, ranging from household appliances to industrial equipment. Its design is relatively simple, with its internal structure consisting of a fixed outer core surrounding an inner rotor. This rotor, usually composed of copper or aluminum conductor strips, is called a "cage," which is where the motor gets its name.

Power range: up to 23 MW

Voltage range: up to 13,8 kV

Shaft height: 355 - 1000 (mm)

Pole number: 2 – 24

Cooling: IC01, IC31, IC611, IC616, IC666, IC81W, IC86W

Protection: IP23, IP24(W), IP55 up to IP66 (optional)

Operating: DOL, VSD

Operating environment: Safe area, hazardous area

Core applications: Pumps, Fans, Blowers, Compressors, Conveyers, Mills, Thruster

This motor works by using electromagnetic induction to generate torque. When current passes through the fixed winding (stator) to generate a rotating magnetic field, this magnetic field will induce the conductor bars in the rotor to generate an induced current, thereby generating a magnetic field on the rotor. This magnetic field will interact with the stator magnetic field to generate torque and drive the motor. Turn.

1. Robustness: The simple design of the squirrel cage rotor makes the motor very reliable and capable of handling mechanical stress, making it an ideal choice for heavy-duty applications.
2. Low maintenance: The absence of brushes, slip rings, and commutators reduces wear, lowering maintenance costs and downtime.
3. Cost effectiveness: These motors are relatively inexpensive to produce, making them an affordable choice for most applications.
4. Self-starting: The Squirrel cage induction motor is self-starting, meaning it does not require any external mechanism (such as a starter or capacitor) to begin operation.
5. Simple construction: The design is simple and easy to manufacture and repair.
6. Energy efficiency: The Squirrel cage induction motor can be very energy efficient, especially when used in variable speed applications controlled by a VFD (Variable Frequency Drive).
