Title:
DC MOTOR CONTROLLER
Document Type and Number:
Japanese Patent JP2016083237
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a DC motor controller capable of suppressing a circuit scale even if a control range of a rotation amount of a DC motor to be controlled is wide.SOLUTION: A DC motor controller 1 comprises: communication units (10, 11) for receiving control commands which specify target rotation amounts of DC motors (2-1, 2-2); sensor interface units (13-1, 13-2) for receiving detection signals from rotation angle sensors (4-1, 4-2) for outputting the detection signals each time the DC motors rotate by a predetermined rotation angle; step number count units (14-1, 14-2) for outputting count signals each time the detection signals are received by a predetermined number; control units (15-1, 15-2) for calculating step numbers indicating total rotation amounts from the rotation start of the DC motors based on the received number of the count signals, and generating control signals for controlling the DC motors according to the step numbers and the target rotation amounts; and drive signal generation parts (16-1, 16-2) for generating drive signals for rotating the DC motors according to the control signals.SELECTED DRAWING: Figure 2
