1. A voltage controller, comprising:
- a control circuit that controls a voltage of electric power generated in an alternator of a vehicle while generating heat; and
a heat radiating member, having a first surface and a second surface, that receives the heat generated from the control circuit through the first surface and radiates the received heat from the second surface,wherein the second surface of the heat radiating member has a smooth and flat shape, andwherein the heat radiating member is disposed such that a plane including the second surface intersects, at an angle greater than zero degrees, with a line along a radial direction that is perpendicular to a rotation axis of a rotor of the alternator and the line directs from the rotation axis to a center of the second surface of the heat radiating member.

Abstract
A voltage controller has a control circuit and a heat radiating member attached to the circuit. The circuit controls a voltage of electric power generated in an alternator of a vehicle while generating heat. The member has a first surface and a second surface. The second surface of the member is formed in a smooth shape having no protrusions or hollows. A cooling wind flows on the second surface. The member receives the heat from the control circuit through the first surface and radiates the heat from the second surface to the wind.

11. An electric rotary machine, comprising:
-
an electromagnetic interaction unit, having a stator and a rotor, that electromagnetically induces electric power in the stator from a rotational force of the rotor or electromagnetically converts electric power supplied to the stator to a rotational force of the rotor and outputs the induced electric power or the converted rotational force; a control unit that controls the electromagnetic interaction unit to output the induced electric power or the converted rotational force set at a predetermined value, and generates heat during the control of the electromagnetic interaction unit; and a heat radiating member, having a first surface and a second surface, that receives the heat generated from the control unit through the first surface and radiates the received heat from the second surface, wherein the second surface of the heat radiating member has a smooth and flat shape, and wherein the heat radiating member is disposed such that a plane including the second surface intersects, at an angle greater than zero degrees, with a line along a radial direction that is perpendicular to a rotation axis of a rotor of the alternator and the line directs from the rotation axis to a center of the second surface of the heat radiating member. - View Dependent Claims (12, 13, 14, 15)
