Title:
ACTUATOR CONTROL DEVICE, ITS CONTROL METHOD, AND CONTROL PROGRAM
Document Type and Number:
Japanese Patent JP2020048335
Kind Code:
A
Abstract:
To prevent false detection of magnetic pole switching and to control the drive of actuators such as motors with high accuracy.SOLUTION: A motor 1 has a driver and a stator, and a CPU 101 controls a motor driver 104 to drive the driver by applying a current to the stator. Magnetic sensor circuits 8 and 9 detect the position of the driver, and the CPU exclusively controls the timing of detection by the magnetic sensor circuits and the timing of applying the current to the stator.SELECTED DRAWING: Figure 1
