When Downtime Is Not An Option.



Why People Are Wary of Motor Rewinding Services

Why People Are Wary of Motor Rewinding

Electric motors are key components in most civilian, military, and industrial vehicles. But like all machine parts, prolonged use will cause motors to wear down and eventually burn out. When that happens, you are faced with a dilemma: should you replace the motor, or visit the best motor rewinding San Diego has to offer? If the magnetic core of your motor is healthy and the proper procedures are followed, a rewound motor will retain its original efficiency. Motor rewinding services can even restore an energy-efficient motor to its normal high performance.

While getting more mileage out of the motor you already own, be it alternating or direct current type, is an attractive option, you should consider a few things before turning to motor rewinding services. A failed motor presents an opportunity to upgrade. Especially if your motor is a decade or more old, or has been incorrectly rewound in the past.

The Payback Problem

The more hours a motor runs per year, and the more horsepower it provides, the higher the operating cost and the higher the emphasis on maintaining high efficiency. Motors that are small or used rarely require a lot less expenditure to run even if they have a lower efficiency.

You must ask yourself: is it a good idea to spend a certain amount to have the motor rewound, which would keep the operating costs the same or potentially higher? Or should you spend a larger amount to replace your old motor with a newer energy-efficient motor that will reduce your operating costs in the long run?

It may be worth spending more money upfront and cut the costs in the long run.

Damage to the Stator Core

Typical induction motors utilize a rotating armature placed within a fixed stator. It’s comprised of a core of iron laminations that are stacked and insulated, as well as windings of copper wire. Stator winding insulation tends to fail due to extreme one-time heating, water entering the motor, or just repeated motor overheating. In this case, the core is usually undamaged, and can be rewound if the old winding is taken out first.

When the motor fails because of bearing failure, it often results in stator core damage caused by the armature grinding against the stator iron and burring the edges of the laminations. Such damage is death to the motor.

Regardless of the cause of motor burnout, it’s important to ascertain if the stator core is undamaged before attempting repairs. Rewinding a motor with a damaged stator core will result in a motor with worse thermals, reduced efficiency, and the increased chance of another burnout.
