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:
