摘要： A carbon brush holder with improved air vents includes a body, a housing, and an exhaust lid, which are provided with corresponding fixing structures for their convenient assembly or disassembly. The exhaust lid is formed with a diverging air channel. By the exquisite configurations of the fixing structures provided on its components, the carbon brush holder is easy to assemble and disassemble so as to facilitate replacement or repair of parts settled in the carbon brush holder. Besides, since the exhaust lid in the present invention has the diverging air channel opened at two sides thereof as the air vents, it significantly improves the efficiency in dust expelling and heat dissipating, thereby effectively preventing the air vent from blocked and preventing overheat caused by poor exhaust.

摘要： An electrical current collector system has an electrically conductive slip ring mounted to a rotatable shaft and a fixed conducting ring assembly forming a partially enclosed AC high voltage electrical current conductive ring channel in which slip ring contacting members are mounted. A compartment at ground potential at least partially encloses the slip ring and the fixed conducting ring assembly. A source directs a fluid into the compartment so that the fluid travels through into the conductive ring channel to perform at least one of cooling and cleaning of the slip ring contacting members. A hollow conically shaped insulator has a frustum with a narrower cross-sectional opening connected to the conductive ring channel and a larger diameter cross-sectional portion passing through and connected to the compartment for exhausting the fluid from the current conductive ring channel.

摘要： A starter having a speed reduction mechanism that can reduce the mechanical and thermal loads that harm a starter motor. By setting the upper and lower coil ends and of upper and lower armature coils approximately parallel to the end side of the armature core, and by connecting the upper coil end and lower coil end, the upper and lower coil ends can be stored in an axially projecting small space adjacent the armature core. As a result, the anti-centrifugal force of the armature can be increased, and the mechanical load applied to the starter motor can be drastically reduced. As the upper and lower coil ends are near the armature core, the heat generated by the upper and lower coil ends is easily dissipated to the armature core, and the thermal load applied to the starter motor can be reduced.

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： In a fractional horsepower PMDC motor a varistor comprises an annular ring of varistor material having a heat sink bonded to one face. The heat sink includes a plurality of fan blades and is attached to a commutator of the motor. The heat sink increases the thermal capacity of the varistor to resist overheating under stall conditions and improves heat dissipation when the motor is running.

摘要： An enclosure for a collector set on a turbine generator includes a non-conducting transverse baffle which divides the enclosure into a separate compartment for each polarity. An aperture in the baffle forms with the generator shaft an annular passage through which cooling air passes from one compartment to the other and in so doing flows directly over the collector ring and brush sets in each compartment to provide more efficient cooling. A removable housing is guided into place over the collector set by a grooved guide which engages the top edge of the baffle and forms a seal between compartments. Single doors on each side of the housing provide access to both polarities and carry a seal, which mates with the baffle with the doors closed, to force the air to pass through the annular passage. An insulated safety handle above each door provides support when leaning inward to change brushes with the generator at full load, and discourages inserting both hands into the enclosure at once.
