Open loop control is used to control the speed of the motor by honestly controlling the duty cycle of the PWM signal to drives the motor-drive circuitry.
Designed specifically for the open loop control of stepper motors sized Nema 17 to Nema 34, Nanotec Electronic GmbH & Co.
However, the gain of the open loop control system is adjusted by a feedback control of the frequency signal, so that the whole open loop gain crosses the 0 dB point at the desired switching frequency.
This type of motor is characterized by a particular structure similar to that of the rotary stepper motor and it is widely used in open loop control.
Nevertheless, the approach does present a remarkable advantage towards a traditional open loop control.
