125 HP Squirrel Cage Induction Motor
To power your squirrel cage, you will need a motor that has a minimum of 40 hews and a maximum of 125 hews. To find the minimum size of this motor, use the following chart:

The basic components of a squirrel cage induction motor include a stator, rotor, fan, and bearings. The stator is comprised of three-phase windings that are spaced at 120 degrees. The stator is mounted on a laminated iron core. The windings are wrapped around the stator core to provide a low-reluctance path for the flux.
The squirrel cage induction motor is most common in industrial applications, and it is particularly well-suited for tasks that require constant speed. It is also known as a wound-rotor motor. Slip ring induction motors are not as popular and have a few disadvantages. The simplest and most affordable squirrel cage induction motor is a four-pole design that has a synchronous speed of 60 f/p and a full-load operating slip of 3 per cent.
The squirrel cage induction motor is classified into seven classes based on their torque. The larger motors fall into Class A, while smaller motors fall into Classes B and C. These classes are interchangeable and can be used in the same application. If you’re buying a squirrel cage induction motor for industrial use, be sure to check the specs before buying. You’ll want to consider the voltage and speed specifications of the motor before purchasing it.
The most important part of a squirrel cage induction motor is its rotor. The rotor rotates to produce the mechanical output. The mechanical output is listed on the nameplate of the motor. The rotor consists of a shaft and short-circuited copper/aluminum bars. The rotor core is laminated to minimize losses due to eddy currents and cogging during starting operation. A fan is attached to the back of the rotor for proper heat exchange and to keep the motor temperature under limit.
When wiring a squirrel cage induction motor, be sure to use three standard non-time-delay fuses as protection. In addition, there should be a safety switch installed on the line side of the magnetic starter. To protect your motor from overheating, you should install a circuit breaker and a motor-circuit switch with a horsepower rating. The safety switch must also be a molded-case switch or a circuit breaker.
125 hp squirrel cage induction motor
A 125 hp squirrel cage induction or “squirrel” cage motor is one of the many popular types of industrial motors. This type of motor has numerous advantages over other types of motors, including low price, simplicity, safety, and heat regulation. However, the lack of speed control makes this motor less than ideal for some applications. The good news is that squirrel cage induction motors are available in a variety of sizes, and are easily customizable to suit your needs.
A typical squirrel cage induction motor features a rotor made of steel laminations with copper or aluminum conductors embedded in the surface. The non-rotating stator is connected to a power source via a wire wound around laminated metal sheets. When the power source turns, the current in the stator changes, producing a rotating magnetic field. The induced current in the rotor winding increases with the rotation rate of the stator’s magnetic field. As a result, the two magnetic fields interact to produce rotation and torque on the rotor.
The basic working principle of squirrel cage induction motors is the same as that of other induction motors. The key difference between them is their specific interaction between rotor and stator. They work at base speeds and torques and reach a steady state through a transient start-up process. The torque-speed curve is usually depicted as the starting torque and rated speed. The difference between synchronous speed and torque defines the slip of a motor.
For safety, a squirrel cage induction motor should be connected to a line voltage of the rated line. It must be protected from overheating by a safety switch, which consists of three non-time delay fuses. The safety switch for the squirrel cage induction motor must be a motor-circuit switch or a circuit breaker with the correct horse power rating. The safety switch for a squirrel cage induction motor should be located on the line side of the magnetic starter.
