Title:
MOTOR CONTROLLER AND SLOT MACHINE
Document Type and Number:
Japanese Patent JP2020188589
Kind Code:
A
Abstract:
To provide a motor controller that can improve the accuracy of position in stopping the rotation of a rotating body driven by a motor.SOLUTION: A motor controller comprises: a deviation calculation unit 15 that calculates, as a deviation amount, the difference between the number of detection signals that are received in a period from when the rotational position of a rotating body 5 driven by a motor 2 reaches a predetermined reference point until when the rotational position of the rotating body 5 reaches the reference point next, and output from a rotation angle sensor 4 every time the motor 2 rotates by a predetermined angle, and a reference number of detection signals equivalent to the amount of rotation of the motor 2 corresponding to the amount of rotation of the rotating body 5 in the period; and correction units (12, 14) that correct positional information indicating the rotational position of the rotating body 5 according to the deviation amount and a correction amount equivalent to the deviation of a stop position from a target stop position in stopping the rotation of the rotating body 5.SELECTED DRAWING: Figure 1
