Title:
MOTOR CONTROL DEVICE AND GAME MACHINE
Document Type and Number:
WIPO Patent Application WO/2018/168085
Kind Code:
A1
Abstract:
A motor control device 1 has: a drive signal generation unit 14 that generates a drive signal in accordance with the rotational torque generated by a DC motor 2 and outputs the drive signal; a sensor interface unit 15 that receives a detection signal from a rotational angle sensor 4 for outputting the detection signal every time the DC motor 2 rotates by a predetermined rotational angle; a speed measuring unit 21 that measures the rotational speed of the DC motor 2 on the basis of the received detection signal; a brake value calculation unit 22 that calculates a brake value of the drive signal on the basis of a specified stop required time and the rotational speed, said brake value being used for stopping the DC motor 2 within a stop required time; and a stopping unit 25 that makes the drive signal generation unit 14 output the drive signal having the brake value over the stop required time.
