Appl. No.:
12/255863
Inventors:
Johnny D. Yu - Centerville OH, US
Joseph A. Zahora - Kettering OH, US
Joseph A. Zahora - Kettering OH, US
Assignee:
Dayton-Phoenix Group, Inc. - Dayton OH
International Classification:
H02K 17/00
US Classification:
310211, 31021693
Abstract:
An AC-induction-motor rotor lamination has a longitudinal axis and circumferentially spaced apart and closed rotor slots. Each rotor slot includes first through fifth corners, a straight slot base, straight first and second slot sides, and first and second curved sides. The slot base extends from the first corner to the second corner, the first slot side extends substantially radially inward from the second corner to the third corner, and the second slot side extends substantially radially inward from the first corner to the fourth corner. The first and second curved sides extend from a corresponding one of the third and fourth corners to the fifth corner. A rotor lamination having slot sides extending substantially radially outwardly from the second and first corners, and rotor laminations having open rotor slots (with slot sides extending substantially radially inward or outward) are also described.

Johnny D. Yu - Centerville OH, US
Assignee:
Dayton-Phoenix Group, Inc. - Dayton OH
International Classification:
B60K 11/04
US Classification:
180 684
Abstract:
Apparatus including a locomotive-radiator-cooling-fan tankhead assembly having a substantially-circular base plate and a substantially-circular outer ring. The base plate has a central longitudinal axis and a circumference. The outer ring is substantially coaxially aligned with the central longitudinal axis and is attached to the base plate proximate the circumference. The base plate has a substantially-planar first surface having a central recess substantially coaxially aligned with the central longitudinal axis and having circumferentially-separated, first and second peripheral recesses each radially spaced apart from the central recess and extending radially inward from proximate the circumference. The outer ring longitudinally extends beyond the first surface. The tankhead assembly is devoid of any gussets attached to the base plate and is devoid of any gussets attached to the outer ring.

Assignee:
Dayton-Phoenix Group, Inc. - Dayton OH
International Classification:
H02K 3/34
US Classification:
310215, 29596, 29597, 29598
Abstract:
Apparatus including a monolithic, motor/generator phase insulation article having a manufactured state and a ready-to-use state. The insulation article has longitudinally-spaced-apart first and second tabs and flexible, transversely-spaced-apart first and second legs each having a first end monolithically joined to the first tab and a second end monolithically joined to the second tab. The first and second tabs are disposed longitudinally closer together in the manufactured state than in the ready-to-use state. In the manufactured state the first and second legs each have a more serpentine shape, and in the ready-to-use state the first and second legs each have a less serpentine shape. A method for manufacturing the insulation article is also described which cuts a monolithic, substantially-rectangular sheet of motor/generator phase insulation to create the insulation article.

International Classification:
H02K 1/04
H02K 15/12
H02K 15/12
US Classification:
310 45, 310 43, 310214, 310215
Abstract:
A heavy-duty stator core and coil assembly that can accommodate severe input voltage spiking and harmonics may include a coat of varnish applied to the stator core and coil assembly by steps of dipping the stator core and coil assembly end-first along a longitudinal axis into a first tank of liquid epoxy resin having a relatively low viscosity, baking the coating, inverting the stator core and coil assembly and applying a second coat of varnish in the same manner, then dipping the core and coil assembly into a second tank having a liquid epoxy resin of a relatively high viscosity, then baking the second coat.
Cooled Fan Motor And Method Of Operation
View pageUS Patent:
8587165, Nov 19, 2013
Filed:
Mar 30, 2011
Appl. No.:
13/075737
Inventors:
Joseph A. Zahora - Oakwood OH, US
Harley J. Weldy - Covington OH, US
Harley J. Weldy - Covington OH, US
Assignee:
Dayton-Phoenix Group, Inc. - Dayton OH
International Classification:
H02K 9/00
US Classification:
310 67R, 310 52, 310 58, 310 59, 310 62
Abstract:
A cooled fan motor may include a tankhead, an elongate housing attached to the tankhead and, having at least one longitudinally extending groove, a shaft rotatably attached to the housing, a hub attached to the shaft, the hub having at least one opening therethrough and shaped to form a gap with the tankhead, a rotor attached to the hub, and a stator mounted on the housing such that the groove in the housing forms an air passage between the housing and the stator connecting the gap and the opening; whereby air external to the motor is able to enter through the gap, flow along the air passage and exit the motor through the opening in the hub, thereby cooling an interior of the motor.
Control For Multi-Phase Induction Motor

International Classification:
H02P 1/32
US Classification:
318779, 318727, 318767, 318771, 318778
Abstract:
A method for controlling operation of a multi-phase induction motor may include transmitting a high-speed operation signal by a master computer for high-speed operation of the motor; receiving the signal by a control signal board, and in response to the signal, the control signal board may sense that the master computer is not simultaneously transmitting a low-speed operation signal, and in response to receiving the high-speed operation signal and not simultaneously receiving the low-speed operation signal, closing delta-to-wye contactors and closing contactors in a power section to transmit power to the motor for high-speed operation, whereby the motor is connected to a source of multi-phase power and operates at high-speed; and the control signal board transmitting a first feedback signal to the master computer that the motor is connected to the source of multi-phase power and is running at high speed.

Joseph A. Zahora - Kettering OH, US
Bradley S. Bryant - Xenia OH, US
Assignee:
Dayton-Phoenix Group, Inc. - Dayton OH
International Classification:
H02K 3/493
US Classification:
310214
Abstract:
A dynamoelectric-machine stator includes a stator lamination stack, a plurality of electrically-conductive magnetic wedges, a plurality of electrically-insulative nonmagnetic wedges, and coil windings. The stator lamination stack has circumferentially-spaced-apart stator teeth. Adjacent stator teeth each have a tooth side bounding an intervening stator slot. Adjacent stator teeth each have a radially-outermost tooth tip which circumferentially projects from the corresponding tooth side into the intervening stator slot to partially close the intervening stator slot. The coil windings are randomly wound in the stator slots. The magnetic wedges are each positioned in a corresponding stator slot and physically and solid-magnetically contact the corresponding tooth tips to fully close the corresponding stator slot proximate the corresponding tooth tips. The nonmagnetic wedges are each positioned in a corresponding stator slot between the corresponding coil windings and the corresponding magnetic wedge. A stator-slot magnetic wedge of particular shape is also described.
Receptacle Assembly For Electric Power Leads
View pageUS Patent:
60958715, Aug 1, 2000
Filed:
Feb 24, 1998
Appl. No.:
9/028914
Inventors:
Joseph A. Zahora - Kettering OH
Johnny D. Yu - Centerville OH
Johnny D. Yu - Centerville OH
Assignee:
Dayton-Phoenix Group, Inc. - Dayton OH
International Classification:
H01R 13502
US Classification:
439695
Abstract:
A receptacle assembly apparatus for electric power leads that includes a receptacle, a backshell, and a disk-shaped member clamped therebetween. The receptacle has a housing and a grommet having orifices formed therethrough to receive power leads and associated pins. The disk-shaped member is formed of a relatively hard dielectric material such as nylon and contains orifices therethrough, corresponding to orifices in the grommet, which receive the electric power leads and associated pins. The lead pins have annular ribs formed thereon such that the ribs are captured between a collar on the disk-shaped member and a protrusion on the grommet, thereby preventing relative rearward movement of the lead pins and associated leads.
