Document Type and Number:
Japanese Patent JP7275935
Kind Code:
B2
Abstract:
To provide a motor control device capable of determining whether or not motor position detection switches have abnormalities more accurately.SOLUTION: A motor control device 100 comprises: a current control switch 121 for selecting whether to apply a first current or a second current larger than the first current to position detection switches 20a-20c that are on/off-controlled depending on a drive position of a motor 10, according to on/off of the current control switch; and a controller 130 that monitors the on/off state of the position detection switches 20a-20c and controls the motor 10 and the current control switch 121. The controller 130 on/off-controls the current control switch 121 so as to apply the second current to the position detection switches 20a-20c, and then, detects abnormality information on abnormalities of the position detection switches 20a-20c on the basis of whether or not the on-off state of the position detection switches 20a-20c is deviated from a state predetermined depending on the drive position of the motor 10.SELECTED DRAWING: Figure 1
