Mechanical Faults : Mechanical faults are such types of faults which are generally occurred in the internal housing of a three-phase induction motor. Mechanical faults in three phase Induction Motor This specific phenomenon of induction motor is called crawling.

This fault occurs when the motor is fully loaded with full supply voltages then it does accelerate but it runs nearly one-seventh of its synchronous speed. During this fault, the motor could be totally damaged, or coils of that specific phase could be damaged.Ĭrawling Fault : Crawling fault is basically an electromechanical fault in a three-phase induction motor. Inter Turn Short Circuit Fault : Inter turns short circuit fault is such type of fault when two turns of the same phase or different phases are short-circuited. In this condition when anyone will touch this motor then he will feel the heavy shock beside this, the motor would take over current that could be dangerous for induction motor. Over Load Fault : This fault occurs when the motor is overloaded means the higher load is connected at the output side of the motor and due to this load motor could be heated up or excessive vibration.Įarth Fault: Earth fault occurs when anyone phase of supply voltages is connected to the housing of the motor then the motor is totally shorted. The limit of three-phase ac supply voltages is 380 to 440 so when supply voltages have crossed this limit then the motor could be burned or heart up. Under or Over Supply Voltages Fault: This fault occurs when supply voltages are under or over the specified limit. Due to this fault, the direction of rotation of the motor has changed.

Reverse Phase Sequencing Fault : Reverse phase sequencing fault occurs when any one phase of the three-phase voltage supply is reversed means the phase order of supply voltages is swapped. Due to this fault, the motor could be burned or heat up. Single Phasing Fault : Single phasing fault occurs when any one phase of the supply voltage is getting lost because three phases of the voltage supply are must require for the normal working of a three-phase induction motor. Applications of Three Phase Induction Motor:Įlectrical faults in three phase Induction Motor Three-phase induction motors are used extensively in domestic and industrial appliances because these are rugged in construction requiring little to no maintenance, comparatively cheaper, and require supply only to the stator. Wound Rotor or Slip Ring Induction Motor.On this ground, Induction Motor is also classified as: This armature winding is connected to the 3 phase power supply and carried the load current.īased on the rotor construction, it can be of two types: Squirrel Cage Rotor and Wound Rotor. When balanced three-phase current flows through this winding, a constant amplitude rotating magnetic field is created in the air gap. Three-phase armature winding is wound on the stator. The load is coupled to the rotor shaft of the motor. The stator is the stationary part whereas the Rotor is the rotating part. Three Phase Induction Motor – It has two major components, Stator and Rotor. These motors are widely used in domestic and industrial applications. The single-phase induction motors are used in low power applications. Capacitor Start Capacitor Run Induction Motor.Single Phase Induction Motor – It may be classified on the basis of their construction and starting methods. There are mainly two types of induction motor on the basis of power supply, Single Phase Induction Motor and Three Phase Induction Motor. In an induction motor, the electric current in the rotor needed to produce torque is obtained via electromagnetic induction from the rotating magnetic field of the stator winding. Induction motors are the most frequently-used type of motor used in residential, commercial, and industrial sectors.
