As a result of this arrangement, it is attained that a very high heat transfer coefficient is present, because of the high flow speed of the cooling air flow (22, 22′, 22″).

摘要： A novel homopolar machine with at least one electrically conductive rotatable rotor having at least one predetermined current path, a plurality of current channel insulation layers, and a magnetic field source configured to apply a magnetic field penetrating the rotor and intersecting the current channels when the rotor rotates. The current channel insulation layers are configured for anisotropic current flow both to inhibit eddy currents and to channel current flow between predetermined correlated brush pairs. Two particular configurations are proposed, wherein the source of magnetization generates in the rotor two separate zones with magnetic flux in opposite directions, while the current channel insulation layers guide the current consecutively through these so as to generate the same rotation-sense of Lorentz force.

摘要： Disclosed is an improvement to the stability of D.C. motor brushes mounted in brush boxes with wings is improved by angling the wings toward the commutator such that the brush spring contacts the brush at one or more points intermediate the ends of the brush. Improved cooling is provided by utilizing an end plate with apertures and a brush plate which in combination with the commutator, provides a brush plate aperture for cooling air flow. In a preferred embodiment, speed variations of the motor can be achieved by selectively disconnecting one or more brushes in a four brush embodiment reducing the torque and rotating speed of the motor. In a preferred embodiment, the use of a diode to interconnect same polarity brushes permits a speed change to be accomplished by selectively connecting one or the other end of the diode. In a further preferred embodiment, the stalling of the motor having power applied is indicated by an electronic output where voltage applied to one brush is filtered through an RC filter with the output amplified and voltage doubled. A ripple output indicating that the motor is rotating after amplification will light a light emitting diode indicating proper operation of the motor.

摘要： A module for an electronic circuit of chip or hybrid design, combined with a brush holder for generators in motor vehicles has connecting lines embedded between the electronic circuit, the carbon brushes and a plug-in terminal in a housing component made of insulating material. The circuit which is bonded or soldered to a bearing plate is surrounded, for the purpose of making contact with the contacting lines by a collar of the housing component which is closed by a lid. For good dissipation of heat and cost effective manufacture of this module, the bearing plate with the circuit is to be attached directly to the generator housing and the brush holder with its contact components for the brush terminals is also to be formed on in one piece to the housing component.

摘要： A dual-face, internally-mounted cooling fan is provided in a dynamoelectric machine, e.g. an alternating current generator. The generator includes a ventilated housing supporting a stator assembly and a rotor assembly. The fan includes a divider disk having a plurality of blades provided on each surface and is mounted to rotate with the rotor assembly. As the fan is rotated, a plurality of separate air currents are drawn axially into the housing for cooling. The divider disk prohibits substantial mixing of currents drawn from opposite ends before they are radially expelled from the housing.
