| <P>PROBLEM TO BE SOLVED: To provide an electric motor vehicle using a DC brushless motor, capable of achieving regenerative control with ease and high accuracy for cases where rotational speed is idling speed or more. <P>SOLUTION: The fact that the rotational speed is higher than the idling speed is determined when the regenerative duty ratio is 0%, for example. In such a case, the regenerative current is controlled by inserting a core to increase the magnetic field when the detected regenerative current is less than the targeted regenerative current and by removing the core to decrease the magnetic field when the detected regenerative current is greater than the targeted regenerative current. This prevents overspeed and enables the rotational speed in travelling over the idling speed to be appropriately adjusted based on the regenerative current. This control is effectively performed in such a simple structure as to increase or decrease a distance between a stator and a rotor, thereby achieving the regenerative control with facility and high accuracy. <P>COPYRIGHT: (C)2009,JPO&INPIT | ||||||

| PURPOSE:To eliminate the noise due to electromagnetic sound by controlling a current flowing through a control side coil by a current controller and controlling the impedance of a load side coil. CONSTITUTION:When the resistance of a variable resistor 14 is zero, the synthetic resistance value of a load voltage regulator 32 is only the resistance value of a semi-fixed resistor 13, a current flowing through the base of a transistor 28 increases, and the current which flows from a DC power source circuit 21 through a resistor 34, between the collector and the emitter of the transistor 28 to the control side coils of reactors 26, 26' increases. Accordingly, the reactors 26, 26' approach saturated state, the impedance of the load side coil becomes small, and the maximum voltage is applied to the load 3. In this manner, the voltage to be applied to the load 3 can be arbitrarily set by regulating the resistances of the resistors 12, 13 by switching a changeover switch 11. | ||||||

| PURPOSE:To prevent the generation of magnetic sound and electromagnetic sound by controlling a current flowing through a control side coil by a current controller and controlling the impedance of a load side coil. CONSTITUTION:When the resistance value of a variable resistor 14 is zero, the synthetic resistance value of the load voltage regulator 32 becomes only the resistance value of a semi-fixed resistor 13, the current flowing through the base of a transistor 28 becomes large, and a current which flows from a DC power source circuit 21 through a resistor 34, between the collector land the emitter of the transistor 28 to the control side coils of reactors 25, 26 increases. Accordingly, the reactor 26 aproaches saturated state, the impedance of the load side coil becomes small, and the maximum voltage is applied to the load 3. When a changeover switch 11 is switched and the resistors 12, 13 are regulated, the voltage applied to the load 3 can be arbitrarily regulated. | ||||||
