Electric motors are used in many different ways, but some are large and dedicated to specific uses that are expensive to replace if they stop working correctly. An electric motor rewind may be the best option for these motors, but it needs to be done correctly, or the motor may still not work correctly.
The winding inside your electric motor is a series of wires wound into a coil around an iron magnet. The shaft that spins in the center of the winding has several opposing magnets on it, and when a current is applied to the winding, the magnetic force is amplified, and the shaft begins to spin.
Over time, the magnets begin to wear, and the coil can start to break down with use. An electric motor rewind essential means replacing the winding or core with a new one. Still, the coil must be wound properly, or the electricity passing through it will not have the correct effect, and the shaft will not spin inside the winding.
If you are considering having a motor repaired or rewound, the work needs to be done in a shop that understands how the windings work and has the equipment to reproduce the winding for your motor. Often the windings are made on a machine built specifically for that purpose and can produce a tight, well-formed winding that will move electricity efficiently through it to amplify the magnetic poles properly.
When you are considering having an electric motor rewind done, it is essential to look at the cost involved. If you can get a replacement motor, it is often cheaper than rebuilding or rewinding the one you have. If you can't get the motor or the wait times are too long, and you need to get the machine up and running, your only option could be an electric motor rewind.
It is a good idea to take the electric motor to the shop and have them evaluate it to determine the cost of the repair. In some cases, the motor may not be a candidate for rewinding because of the damage inside the motor. The motor will need to be disassembled and inspected before the repair shop can give you a price for the work, but most shops will be able to estimate the cost for the worst-case scenario if you need a ballpark figure to start with.
The winding may not be the only damage inside the case, so replacing bearings, magnets, and even the driveshaft could become necessary as the motor is taken apart and inspected. The shop will let you know once they have a final price and have determined if an electric motor rewind is possible for your motor.
