After updating the table, the drop-down list below lets you select whether to display the number of slots per pole per phase, the maximum possible fundamental winding factor, the number of winding symmetries, or the least common multiple between the number of poles and the number of slots in the table. In the case of capacitor start induction motor, the centrifugal switch is provided to disconnect the starting winding when the motor attains a speed up to 75 to 80 of the synchronous speed but in the case of capacitor start capacitors run induction motor. To get started, choose the approximate range of number of poles and number of slots that you are interested in. The performance characteristics of a single phase-winding induction motor are obtained from an extensive experimental investigation of the effect of air-. So, these motors produce very high starting torque. Determine number of slots and number of poles In no event shall Emetor be liable to any party for any damages arising out of the use of information from this winding calculator. You can compare the maximum fundamental winding factor for different combinations of number of poles and number of slots, display the winding layout for different coil spans, or evaluate the harmonic spectrum of the winding factor.Įmetor specifically disclaims any warranties, including, but not limited to, the implied warranties of merchantability, accuracy, or fitness for any particular purpose. You can investigate three-phase integer-slot, fractional-slot and concentrated windings, both with single and double winding layers where appropriate. The winding calculator allows you to find the optimum winding layout for your electric motor in a fast and convenient way. Please enable JavaScript in your browser preferences, then try again.
