Motor drive control device, motor driving system, and control method of motor drive control device

摘要

Problem to be solved: to provide a motor drive control device, a motor driving system, and a control method of a motor drive control device capable of optimizing the driving efficiency of the respective motors even when the plurality of motors are simultaneously driven.Motor drive control device 104 includesAt the same time, the target speed is output from the host device to the motor 102 which is subject to drive control of a predetermined number of motorsA receiving section 12 for receiving stable information indicating that the actual revolving speed of a given plurality of motors 102 is stableUpon receiving stable information,An advance / duty determination unit 15 for adjusting a drive control signal SD for controlling the driving of a motor to be controlled as a drive control so as to minimize the motor current at a target rotational speedDuty setting section 16Advance angle control section 17Electric current control unit 18 andBased on the drive control signal SD, there is provided a motor driving section 20 for driving the motor 102 to be driven and controlled.Diagram
