So-called sinusoidal windings, which offer improved performance compared with standard windings, have been used in practice for many years. Unfortunately, many motor repair shops pay little or no attention to this fact. Instead, they have developed their own simplified replacement procedure, apparently just to make the job easier! Their procedure is fundamentally wrong. They simply add up the turns in all coils of a coil group and divide the total by the number of coils in th

Contact us if you need an internal diagram of a three-phase stator for low-speed, gearless motors with a PM rotor, for any slot-pole combination. Attached is the diagram for a commonly used electric bicycle motor with 51 slots and 46 poles. Tip: Use the mouse wheel to zoom and drag with the mouse to move the diagram. Have you ever seen such a clear and clean diagram? Click here to see.

From now on, you can request from us a generated diagram for any two‑speed (PAM, PPM, or Dahlander) or single‑speed three‑phase, double‑layer winding, as well as its complete analysis if needed. Here are a few examples. Contact us.
