Abstract
An example apparatus includes: current driver circuitry configured to supply power to a stepper motor; and controller circuitry coupled to the current driver circuitry, the controller circuitry configured to: determine a first duty cycle of power transferred to the stepper motor by the current driver circuitry during a first operation of the stepper motor, the first operation to supply power using currents of a target magnitude; determine an previous duty cycle of power transferred to the stepper motor by the current driver circuitry during a second operation of the stepper motor, the second operation of the stepper motor to supply power using currents of the target magnitude; and determine changes in a mechanical load applied to the stepper motor responsive to a comparison of the first duty cycle to the previous duty cycle.
