A diode plate for an electric machine includes a body having a thickness and defining a central axis thereof. A plurality of cooling plates having a uniform thickness of 1 millimeter or less over the entire surface area of the cooling plates are mounted onto the body of the diode plate. A plurality of louvered slots may be formed within each of the cooling plates. Each louvered slot has a louvered portion that extends from the cooling plate at a predetermined angle relative to the cooling plate.

The slip ring end (SRE) frame is an SRE frame of popular small dimension designed to allow available larger rectifier assemblies having larger heat sinks to be fitted into the SRE frame, thus providing increased heat dissipation capability. Two flattened frame mounting bore wells are provided in an inner cylindrical side wall of the SRE so that larger rectifier assemblies of choice having increased current carrying capability can fit inside the SRE frame. Specially configured rectifier heat sink mounting holes are provided so that the larger rectifier assemblies may be properly and securely mounted in the SRE frame. Additionally, the small SRE frame features strategically placed ventilation apertures of larger dimension to permit greater air flow through the device, thus producing cooler alternator running temperatures and providing higher durability.

A generator-motor includes a control circuit. The control circuit is provided on an end surface of a motor. The control circuit includes a Zener diode, a capacitor, a U-phase arm, a V-phase arm, and a W-phase arm. The Zener diode, the capacitor, the U-phase arm, the V-phase arm, and the W-phase arm are connected in parallel between a positive bus and a negative bus. The Zener diode absorbs a surge voltage applied to the capacitor, the U-phase arm, the V-phase arm, and the W-phase arm.

摘要:
A motor has a motor unit, an output shaft, a speed-reducing unit for controlling the motor unit, a control circuit board and a gear housing. The speed-reducing unit transmits a rotation of the rotation shaft of the motor unit to the output shaft to rotate slower than the rotation shaft. The gear housing is fixed to the motor unit and includes a generally flat shaped speed-reducing unit receiving portion, which installs at least a part of the speed-reducing unit therein, and a generally flat shaped circuit board receiving portion, which installs the control circuit board therein. The output shaft protrudes beyond and perpendicularly to a side face of the speed-reducing unit receiving portion. The circuit board receiving portion is inclined to the speed-reducing unit receiving portion around a center axis of the rotation shaft to be retracted from an output shaft side of the speed-reducing unit receiving portion.

An induction generator includes a mounting member, a supporting member, a sensing coil unit, and a magnet unit. The supporting member is mounted on the mounting member such that relative rotation between the mounting and supporting members is permitted about a pivot axis. The sensing coil unit is mounted on one of the mounting and supporting members, and has a field-sensing plane. The magnet unit is mounted on the other of the mounting and supporting members, and has a field-emanating plane. An assembly of the supporting member and one of the sensing coil unit and the magnet unit that is mounted on the supporting member has a weight center that is offset from the pivot axis. Relative rotation between the mounting and supporting members about the pivot axis induces electrical current in the sensing coil unit.

A low-noise electric structure of an electric power steering device for automotive vehicles is provided which includes a controller including a substrate on which drive devices working to drive an electric motor are installed. The drive devices, power supply terminal joints, and motor terminal joints are concentrated on a portion of the substrate, thereby permitting a path of current flowing from the power supply terminal joints to the motor terminal joints to be shortened. This results in a decrease in quantity of heat generated from a circuit line extending between the power supply terminal joints and the motor terminal joints.
