An electric motor has various moving parts that wear down over time due to friction. This is a natural process that can’t be avoided, but some maintenance tasks can help you get the most mileage out of your motor before needing a replacement. Motor rewinding can slow the effects of friction on your engine. If your electric motor is starting to operate less efficiently or show signs of wear and tear, here’s some information to know about this service.

What Motor Rewinding Does

Motor rewinding involves replacing the wire coils that wrap around the armature, which is the part that rotates within the stator. Over time, these coils can collect contaminants or wear down due to friction.

When a professional carefully removes the old winding and replaces it with new material, the motor regains its initial efficiency since the new winding is smoother and allows for more fluid motion. This can help avoid an impending burnout or reverse the effects of a recent one.

However, rewinding is not an option for all motors; it can’t fix one with a broken or weak magnetic core. If the core is in good shape and the winding is simply dirty or worn down, this service can effectively restore motion within the stator. 

Signs You Need Motor Rewinding

Aside from an actual burnout, there are a few earlier signs that could indicate a problem with this component. First, corrosion around the metal is a clear sign that it’s losing efficiency. You might notice rust, water, or oil around the material if this is the case.

Additionally, you can measure the insulation resistance, which manages the friction between the electrical components. You can measure it with a megohmmeter, but it’s safer to let an experienced mechanic take care of it. A lower resistance indicates the need for rewinding.

Benefits

When an electric motor wears down or burns out, you can either replace it or have it rewound. Rewinding allows you to get the longest possible lifespan out of a single motor, which ultimately creates less waste and keeps costs down without forcing you to compromise on efficiency.

In addition, rewinding is a fairly quick service, which reduces downtime for companies that rely on their engines for important operations. Also, fixing your current motor is better for the environment than buying a new one.
