BLDC: torque - speed characteristic

Information

Brushless DC machine (permanent magnet synchronous machine) torque-speed characteristic.

This example uses rectangular modulation with constant voltage amplitude and width=2/3, corresponding to 2 phases on, 1 phase off (no additional PWM).

See for example as a function of phase:

  efficiency.eta          efficiency
  machine.motor.w_el       angular velocity (el)
  machine.motor.tau_el     torque (el)
(right click dcm_pm.motor.w_el and choose Independent variable: w_el).
