About this app
Design three-phase induction motors in minutes — not spreadsheets.
Motor Design Calculator is a fast, interactive tool that walks you through the complete design of a three-phase induction (asynchronous) motor. Enter your rated specifications and watch the app build the full design — poles, loadings, stator dimensions, windings, slot and conductor sizing, and air-gap MMF — recalculating every dependent value the moment you change an input.
ONE LIVE, FULLY-LINKED WORKSHEET
Change a single variable — rated power, air-gap flux density, the number of slots — and every quantity that depends on it updates instantly, everywhere, across all eight design stages. No re-typing, no manual recalculation, no flipping between formulas. You always see exactly how each parameter flows into the next.
THE COMPLETE DESIGN SEQUENCE
- Rated specifications — power, voltage, frequency, speed, phases, efficiency, power factor
- Poles & output — number of poles, pole pairs, synchronous speed, output kVA
- Magnetic & electric loading — air-gap flux density, specific electric loading, output coefficient
- Stator geometry — bore diameter, core length, flux per pole
- Electrical parameters — phase voltage, phase current, torque, tangential stress
- Winding design — slots, slots per pole per phase, slot angle, pitch and distribution factors, winding factor, turns per phase, conductors per slot
- Conductor & slot sizing — conductor and copper area, slot area, air gap, tooth and slot dimensions, yoke thickness, outer diameter
- Air-gap MMF — field intensity and magnetomotive force
WHO IT'S FOR
Built for electrical engineering students learning electrical machine design, lecturers preparing worked examples, and practising engineers who need quick preliminary sizing of an induction motor.
WHY YOU'LL LIKE IT
- Instant, transparent results — every formula linked end to end
- Clean, distraction-free interface
- Works completely offline
- No sign-in, no data collection
From coursework and exam preparation to preliminary professional design, Motor Design Calculator turns the entire textbook induction-motor design procedure into a single live worksheet.
