Induction motor overhauling procedure. This standard specification describes the requirements for the contractor to overhaul ashore in a suitable repair facility an alternating current ac induction or synchronous motor removed from a coast guard vessel. Model repair specifications for low voltage induction motors. If there is a little deviation in the shaft rotation the rotor will slowly start touching the stator in this condition you can feel much more vibrations in the motor which can lead to short circuit and burning of windings.

Can you describe the procedure for overhauling a three phase induction motor. How do you overhaul a three phase induction motor squirrel cage. Motor overhauling means first of all check the bearing and shaft level then check the insulations level with megger the insulations is under determine value to improve the insulations level by apply the ctc then apply varnish.

The single phase induction motors are made self starting by providing an additional flux by some. Keep the bearings. Overhaul ac electrical motors.

In this article the care repair service and maintenance of electric squirrel cage motors has been discussed. We have did solo run test to a squirrel cage induction motor at our construction site. Silent and efficient they work 24x7.

There are few simple rules for the maintenance for the motors. Testing and commissioning procedure for electric motors. Diagnosis repair andor overhaul of a motor and to return it to good operating condition with a minimum of delay and cost.

Electric motors are the workhorse of any industry. Overhauling a motor in motor construction the air gap between the stator and the rotor is very less. The problems facing in our plant with lt motors 1when we open motor for overhauling we find a lot of grease inside it even though nipples are provided for grease in.

Standard induction motor has a closed squirrel cage rotor where as open ended induction motor has split phase rotor.
