It's a simple truth, but rewinding an electric motor can be cheaper than replacing it. Take for example this motor from a glass-cutting saw.
It is non-standard and to replace it like-for-like would involve a lead time of about 16 weeks and be very expensive. Our engineers, who are expert in rewinding electric motors, had it repaired within a couple of working days at a cost far cheaper than buying a replacement.
These were the problems they faced:
The stator was rewound, the bearing housing was repaired in our machine shop and the rotor balanced in-house to guarantee the motor will function as it should for years to come.
