Publication number: 20200072244Abstract: A rotary electric machine includes a stator, a rotor, a plurality of coils, and a plurality of flow enhancement members. Each coil has a compound outer surface along major sections thereof with an insulating layer disposed therealong. The compound outer surfaces of each pair of adjacent coils define a channel extending along adjacent major sections of each adjacent pair of coils. One of the flow enhancement members is disposed within each channel between the adjacent major sections of each pair of adjacent coils, with each flow enhancement member defining a gap between the compound outer surface of one of the coils and the flow enhancement member through which cooling fluid may flow.Type: ApplicationFiled: August 28, 2018Publication date: March 5, 2020Applicant: Caterpillar Inc.Inventors: Jonathan M.

Patent number: 9676280Abstract: A system for managing braking torque in a machine uses a first braking system, a second braking system that is independent of the first braking system and a controller that monitors activity in both braking systems. The controller selectively reduces torque in the first braking system as torque in the second braking system increases to limit undesired effects of possible over-braking.Type: GrantFiled: June 9, 2015Date of Patent: June 13, 2017Assignee: Caterpillar Inc.Inventors: Eric Ruth, Christopher P. Braet, Alexander C. Crosman, III, Jonathan M. Baumann

Patent number: 8488293Abstract: An assembly, system and method are provided for discharging a rotating shaft encompassed by a stationary housing. The system includes an annular charge-dissipating component and a biasing element oriented to apply an axial force to the charge-dissipating component, holding it in contact with the shaft and the housing while the shaft is rotating. The biasing element may be a coil spring or a wave spring. A shaft grounding upgrade kit includes a conductive ring member and a cylindrical spring having a diameter that is the same as that of the conductive ring member. The spring constant of the cylindrical spring is such that the spring holds the conductive ring member within the housing in contact with the shaft and the housing. The conductive ring member may be constructed of gray iron and the cylindrical spring is one of a wave spring and a coil spring.Type: GrantFiled: December 15, 2010Date of Patent: July 16, 2013Assignee: Caterpillar Inc.Inventor: Jonathan M.

Patent number: 7547981Abstract: A machine and electrical power system includes a generator having a speed range that includes a resonance speed associated with resonance vibrations of the system. A drive coupling is disposed between the generator and an engine configured to rotate the generator and is further configured to transmit torque from the engine to the generator, the drive coupling being configured to allow relative slip between first and second elements when the generator is rotated at its resonance speed. A machine operation method includes rotating a generator with an engine, and generating resonance vibrations of at least one of the engine and the generator by rotating the generator at a resonance speed. The method further includes inhibiting transmitting resonance vibrations between the generator and the engine by allowing relative rotational slip within a drive coupling disposed between the engine and the generator.Type: GrantFiled: February 9, 2007Date of Patent: June 16, 2009Assignee: Caterpillar Inc.Inventors: Satish Savant, Bradford A.
