Title:
DC MOTOR DRIVING APPARATUS WITH TRACTION REDUCING GEAR
Document Type and Number:
Japanese Patent JP2018143028
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a DC motor driving apparatus that can stably control the rotational speed of a DC motor by reducing the speed of the output rotation of the DC motor using a traction reducing gear.SOLUTION: A DC motor driving apparatus 1 with a traction reducing gear comprises: a DC motor 2; a traction reducing gear 3 for shifting the rotational speed of the DC motor 2 and outputting the rotation through an output shaft; and a control unit 4 for controlling the drive of the DC motor 2. The control unit 4 comprises: a speed command generation unit 11 for generating a speed command value for the DC motor 2 on the basis of the rotational angle of the output shaft of the traction reducing gear 3; a speed computing unit 20 for computing the rotational speed of the DC motor 2 and outputting the rotational speed as a computed speed value; and a drive control unit 12 for driving the DC motor 2 using the speed command value and the computed speed value.SELECTED DRAWING: Figure 1
