|20140312723||ELECTRIC MOTOR FOR VEHICLE - In an electric motor for a vehicle, a fan integrally rotatable with a rotor is located on one end in a direction of the axis of the rotor, a bracket for accommodating the fan is joined on one end in the direction of the axis of a stator frame for accommodating a stator, and the bracket is provided with an outside air inlet and a dust emission outlet. The bracket is provided with an expanded section which has an inner peripheral surface bulging on an outer peripheral side in a radial direction beyond a peripheral surface of the stator frame, and at least a part of the dust emission outlet opens to the inner peripheral surface of the expanded section.||10-23-2014|
|20120060596||CHASSIS DYNAMOMETER - A chassis dynamometer for a vehicle has a base seat, a fixed shaft having one end thereof attached to the base seat, a rotary proximal portion rotatably supported to the fixed shaft, a roller connected to the rotary proximal portion, for loading a wheel of a vehicle, and a motor connected to the roller so that power can be transmitted therebetween. The roller has a single flange portion connected to the rotary proximal portion and extending obliquely to the axis, and an outer peripheral portion extending both axial directions from an outer periphery of the flange portion and disposed outward in the radial direction of the motor.||03-15-2012|
|20120056603||Main circuit of electric power generating apparatus for dispersed power supply - Main circuit of an electric power generating apparatus for dispersed power supply, having a permanent magnet type electric power generator driven by windmill or waterwheel and having three windings, each inducing a different value of induced voltage, AC outputs of the generator rectified by rectifiers, and DC outputs of the rectifiers summed in parallel for output. First and second reactors are respectively connected in series between first and second rectifiers and output terminals of first and second windings, the first winding inducing the lowest induced voltage among the three windings, the second winding inducing the second lowest. A capacitor is connected between a third rectifier and an output terminal of a third winding inducing the highest induced voltage. The sum of inductive impedance by internal inductance of the third winding and capacitive impedance by the capacitor is capacitive impedance within a range of rotational speed of the generator.||03-08-2012|

|20090243294||Main Circuit of Generator for Distributed Power Supply - In an electric power generating apparatus for dispersed power supply using a permanent magnet type electric power generator having many kinds of windings in order to obtain the maximum output by force of wind without using PWM converter, there is a problem that gap magnetic flux of the permanent magnet type electric power generator is demagnetized to decrease the internal induced voltage because alternating current output of the permanent magnet type electric power generator is lagging current. In an electric power generating apparatus for dispersed power supply including a permanent magnet type electric power generator having a plurality of windings inducing different effective values of induced voltages and individual rectifiers for rectifying alternating current outputs of the permanent magnet type electric power generator, a capacitor is connected in series between the individual rectifier and the alternating current output terminal of the winding inducing higher effective value of induced voltage among the plurality of windings in a manner that serial impedances of the capacitor and the permanent magnet type electric power generator become capacitive within the range of rated rotational speed of said permanent magnet type electric power generator.||10-01-2009|
|20090193909||CHASSIS DYNAMOMETER - A chassis dynamometer for a vehicle has a motor having a rotor, rollers on which wheels of the vehicle are disposed, a flange portion extending inward in a radial direction from each of the rollers, and a rotor bracket for supporting the rotor of the motor. The flange portion and the rotor bracket are connected via a torque meter capable of measuring at least an outer peripheral tangential force of said roller.||08-06-2009|
