My own electronics lab for remote work
torque at standstill with sHFI
silent HFI uses phase modulation instead as audible amplitude modulation
The motor starts from standstill with the maximum permissible torque
and is fully controlled even at low speeds.
From a certain speed, the control switches to observer mode.
IPD (initial position detection) followed from silent
HFI signal
