Beschreibung
Zusammenfassung:	A work machine (100) includes a frame (110), a traction system (120) supporting the frame (110), a power source (130) mounted on the frame (110), a switched reluctance motor (205), an inverter (220) configured to control power to the motor (205) from a power source (130), and a controller (210). The controller (210) is configured to receive a signal indicating a desired torque (430) and determine if the desired torque (430) is between an upper threshold (410) and a lower threshold (420). If the desired torque (430) is between the upper threshold (410) and the lower threshold (420), pulse width modulation is used to produce a PWM adjusted torque command (450), and the motor (205) is commanded based on the PWM adjusted torque command (450). The PWM adjusted torque command (450) is configured to cycle between the upper threshold (410) and the lower threshold (420) to produce the desired torque (430).
