Title:
MOTOR CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2015154578
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent reduce noise which is generated when mechanical schemes are abutted with each other by backlash of mechanical schemes (gear trains) mounted to a motor when starting driving the motor, without being influenced by load fluctuation of the motor or a mechanism.SOLUTION: A motor control device includes: a motor for driving a driving part; motor control means for determining a voltage value to be applied to the motor; and rotation detection means for detecting a pulse signal in accordance with a rotation speed of the motor as a count value. When starting driving the motor, until the count value detected by the rotation detection means reaches a predetermined value 1, the motor control means electrifies the motor in such a manner that a voltage value is gradually increased from a driving start voltage of a voltage value smaller than a voltage value capable of rotating the motor. Further, until the count value reaches a predetermined value 2 from the predetermined value 1, the motor is continuously electrified while defining a voltage value at a time point in which the count value reaches the predetermined value 1, as a drive holding voltage.
