Publication number: 20250055394Abstract: A new method and circuit arrangement for operating a stepper motor in a voltage-based operating mode with a control loop over the whole operating range of speeds of a stepper motor. The method/circuit arrangement includes calculating a load angle of the stepper motor. The load angle is then used to calculate a voltage-based control signal suitable for operating a known motor driver circuit, such as a chopper, to drive the stepper motor coils. This enables improved control over the stepper motor which can improve control stability.Type: ApplicationFiled: August 11, 2023Publication date: February 13, 2025Applicant: Analog Devices International Unlimited CompanyInventor: Thomas Ernst
