Any motor that come to your service center could have so called "sinusoidal winding".
Sometimes this fact goes unnoticed and a failed repair is an inevitable consequence.
How to identify sinusoidal winding?
Number of turns per coil is not uniform.
So the number of turns in each coil should be counted.
The worst thing you can do is calculate an average number of t / c and make a uniform coils. Conversion is not so simple.
Even when the conversion to standard winding is done in a correct way, you'll get winding with poorer energy parameters.
Bare in mind that application of sinusoidal winding is not limited to single-phase motors only. A large number of three-phase motors have such a winding.
The most common cases in practice are shown in the table below.
Our recommendation in such a case is: repeat the genuine design.
