A three phase induction motor is an AC-type induction motor that operates on three-phase supply like a single-phase induction motor where a single-phase supply is needed to operate it. An electromagnetic field is produced by three three-phase supply currents in the stator winding which which will produce the torque in the rotor winding of the three phase induction motor in the presence of the magnetic field.
●It has a simple and rugged construction.
●It requires less maintenance.
●It has good efficiency and better power factor.
●It is less expensive.
●It has self-starting torque.

The Outer Casing
The most visible part of the motor is the outer metal casing. For these 3-phase induction motors, there are likely to be a few similarities. First, a sealed wiring box extends out the side. These can contain 3, 6, 9, or 12 wires, with 9 being the most common variation. Weather-resistant gaskets prevent moisture from corroding the wire nuts or screw terminals inside this wiring box.
Motor Cooling Fan
There are many models of motor housing for various environmental situations. General purpose, severe-duty, washdown tolerant, food grade, etc. are just a few examples that can change exactly how a motor is constructed.For this general-purpose situation, it is common to find a fan attached to the drive shaft on the reverse end of the motor, covered by a shroud to protect the blades and operators from damage.
Removing the End Caps
For most smaller motors, a set of long screws secures the front end to the back end, containing the entire assembly together in the middle of the motor case.Once these screws are removed, both ends can be removed with little force.
Front-end Cover
The front end of the motor is removed with a gentle application of force. In this case, it came out with the front motor bearing still firmly press-fit in place.The rotor itself is never attached to either the front or back cover. If it were, it would be unable to spin freely. The goal of the motor design is to construct it with zero vibration (meaning a very tight tolerance bearing) with zero friction (meaning not TOO tight on the bearing). That means the rotor can be removed from both end plates with just a gentle application of force.
The Rotor
The rotating piece in the center of the motor is one half of the interaction that actually makes a motor work. The rotor is a carefully constructed, perfectly balanced shaft of metal with a high iron concentration. This ferrous content allows it to be influenced by the current in the coils around it. As the current progressively charges the winding coils, the rotor responds with a magnetic attraction in incremental degrees around the outside, pushing and pulling it in a circle. Smooth balanced rotation.
Precautions for use of Three Phase Motor
Every motor needs a Starter with Switch, Over load protection and Short Circuit Protection. Single phase preventer is also suggested.
Motors can have Switch fuse unit, MCB or MCCB or MPCB for Over load.
Protection Set FLC given on name plate for Over load Protection.
Fuse rating for Short Circuit Protection as per the motor rating.
There should not be any loose connections. All connections to be made secure.
Voltage at motor terminals should be equal to ensure availability of all three phases.
For Belt-Pulley, Chain-Sprocket & Gear Coupling applications, Optimum belt tension & Alignment to be maintained to avoid excessive load on Shaft & Bearings.
The coupling parts to be fitted on the motor shaft are to be properly balanced.
The bore and key way are to be machined accurately within tolerance for the bore diameter of H7.
