BLDC two-wheeler motor designer app with PMSM comparison (0.25–15 kW)

Design a BLDC hub or mid-drive motor for e-cycles, scooters and motorcycles, and compare six-step BLDC with a PMSM run on FOC.

BLDC hub motor cross-section, six-step block currents, FOC sinusoidal currents and a torque comparison

Aim

Size a BLDC two-wheeler motor (outer-rotor hub or inner-rotor mid-drive), simulate its six-step Hall drive and an FOC-driven PMSM twin switch by switch, and see which suits each two-wheeler segment on efficiency, torque ripple, controller current and cost.

What you’ll learn

  • Trapezoidal vs sinusoidal back-EMF, and how slot/pole choice shapes it
  • Six-step Hall commutation vs field-oriented control (FOC)
  • Commutation torque ripple, cogging and inverter losses
  • Which drive fits e-cycles, city scooters, performance scooters and e-motorcycles
