Advantages and Disadvantages of Rewinding a Stator
Rewinding a stator has some advantages over buying a new one. The first is of course the availability. Not every stator is available as an aftermarket part. Stators for old vehicles may have been discontinued for example. In those instances, the only option is rewinding your stator if you wish to keep riding your vehicle.
Maybe you purchased a rare vehicle and you can’t find an aftermarket stator. In this case, rewinding your stator is the only option to make it work again.
When rewinding your stator, you typically will have a shorter warranty than if you purchased a quality aftermarket stator. This is important since rewinding a stator is done by a single person trying to match the desired specs. The person rewinding your stator is more prone to making errors than a programed machine and may make mistakes in the winding’s direction or when matching the specs.
The person may also make a faulty stator diagnosis, leading to a bad stator rewind which may not work when you get it back.
Rewinding a stator usually makes it less reliable than a good aftermarket one. The best aftermarket stators are wound by machines calibrated to match precisely the voltage output required by the stator.
If you’re in a hurry or on a budget, rewinding a stator is probably not your best option. Rewound stators are often more expensive than aftermarket ones and require time to repair so your vehicle will likely be down longer than if you were to purchase a new aftermarket one.
