Electric motor winding calculator Help icon

With the winding calculator you can conveniently and fast find the optimum configuration for your electric motor winding. You can investigate integer-slot, fractional-slot and concentrated windings, both single and double layer windings. You can compare the maximum fundamental winding factor for different combinations of number of poles and number of slots, display and compare the winding layout for different coil spans, or display and compare the harmonic spectrum of the winding factor for different electric motor windings.

To get started, choose if you want to display the number of slots per pole per phase, the maximum fundamental winding factor, the number of winding symmetries, or the least common multiple between the number of poles and the number of slots. Make your choice in the drop-down list below.
