Abstract
A motor control device main unit includes a pressure command signal generation module, a pressure control module, a speed control module, and a current control module. The pressure command signal generation module of the motor control device main unit generates a pressure command value so that a derivative of the pressure command value is equal to or less than a product of an elastic constant of the pressurized target and a maximum motor speed. The pressure control module carries out pressure control calculation to calculate a motor speed command value based on a deviation between the pressure command value and an actual pressure value, and generates a motor speed command signal, which is a signal of the motor speed command value.
