DRIVE CONTROL DEVICE

A drive control device includes: a processor, and a memory storing instructions that, when executed by the processor, cause the processor to perform operations. The operations include: calculating a duty ratio of a PWM signal based on a rotation speed of a motor driven by a PWM control and a target...

Beschreibung
Zusammenfassung:	A drive control device includes: a processor, and a memory storing instructions that, when executed by the processor, cause the processor to perform operations. The operations include: calculating a duty ratio of a PWM signal based on a rotation speed of a motor driven by a PWM control and a target rotation speed; and obtaining an estimate value of a torque of the motor based on the rotation speed of the motor and the calculated duty ratio.
