    Abstract: A system has an axial field rotary energy device with a housing, an axis and a rotor with a shaft, bearings, rotor disks and permanent magnets. A printed circuit board (PCB) stator is between the rotor disks to define an air gap on each side thereof. A variable frequency drive (VFD) assembly has a VFD housing and first pads coupled to inductors to facilitate heat removal from the inductors. A concave cradle is coupled to a ferromagnetic core and has a same contour as an outer surface of the ferromagnetic core. A second pad is coupled to a rectifier module. A third pad is coupled to switching devices and has pins to align the switching devices with the third pad. Standoffs are coupled to the VFD housing to support a first printed circuit board assembly (PCBA). A second PCBA is mounted to a shield plate above the first PCBA.

  • Patent number: 8409050
    Abstract: A gear retention assembly for retaining a gear that has a plurality of gear outer splines includes a gear housing and a retaining ring. The gear housing has a first end, a second end, and a plurality of inner splines each including a ramp portion. The second end of the gear housing includes an annular continuous rolled lip, where the continuous rolled lip and the ramp portions of the plurality of inner splines define a groove. The plurality of inner splines engage with the gear outer splines of the gear to transmit torque between the gear and the gear housing. The retaining ring is disposed in the groove and axially retains the gear. The rolled lip axially retains the retaining ring.

  • Patent number: 5803222
    Abstract: A friction torque transmitting mechanism has a plurality of reaction plates interleaved with a plurality of friction drive plates. The reaction plates are brought into frictional contact with the drive plates by a fluid operated piston, such that a transfer of torque can be conducted through the frictional engagement of the plates. The reaction plates have a reaction portion disposed in a slot in a housing. One of the reaction plates has an axially extending reaction tab positioned between the reaction portions of the remaining plates and the sidewall of the slot. The reaction forces on the reaction portions are transmitted to the sidewall through the reaction tab.
