Abstract:
    The subject of this invention is to provide a control device for motor which is capable of achieving higher input and where the input control by phase control can materialize in a wide range. The electromotor control device in accordance with the present invention comprises an electromotor which has at least two input terminals on high input side and low input side, and a control means which controls the input of the electromotor by switching the connection into a desired input terminal. This controller performs operation for a specified time with an input terminal on low input side when starting the electric blower. When the electric blower is started, it is surely driven with low input for a specified time, thus this controller can materialize the control that can cope with flicker, by materializing higher input and reducing the current at start.
