摘要： A stator for a generator includes a core having a back iron that is annular in shape and poles that extend inward from the back iron, a hoop having an annular shape that is radially inward from the back iron, and a plurality of winding supports surrounding the poles. Each winding support includes a tooth extending radially inward from the hoop and surrounding a corresponding pole with the tooth having a first end adjacent to the hoop and a second end radially inward from the first end and a first channel on a first axial side of the tooth extending from the second end to the first end. The stator also includes a plurality of windings with each winding wrapped around a corresponding tooth so that each winding is spaced from the tooth at the first channel.

摘要： An electric machine rotor assembly includes a rotor core defining a rotor axis. Windings are seated in the rotor core. A plurality of wedges circumferentially spaced apart around the rotor core relative to the rotor axis. Each rotor core extends axially and separates between two respective portions of the windings. A supply end plate is mounted at a first axial end of the rotor core. A return end plate is mounted at a second axial end of the rotor core opposite the first axial end. A flow path for coolant fluid extends through the supply end plate into the wedges, through the wedges and into the return end plate, and through the return end plate.

摘要： A driven gear includes a radially outwardly extending flange. The radially outwardly extending flange extends along an axial distance defined along a center axis of the flange. The flange merges into a generally conical portion which, in turn, extends radially inwardly to a hub. The hub extends to a remote end. A first distance defined between the remote end of the hub and an end of the flange faces the remote end. A second distance is defined between ends of the flange, with gear teeth formed at an outer periphery. A ratio of the first distance to the second distance is between 2.54 and 2.82. An oil pump, a rotating portion for an electrical generator, and a generator are also disclosed.

摘要： A generator includes a main cavity and a shaft located in the main cavity. The shaft is configured to be connected to an auxiliary power unit (APU) and rotated by the APU. The generator is configured to generate power based on the rotation of the shaft. A fluid system is configured to receive a fluid from the APU, flow the fluid through the main cavity and return the fluid to the APU through a fluid scavenge channel. A filter is configured to filter the fluid from the main cavity to the fluid scavenge channel and a sensor is configured to detect a characteristic of the fluid at the filter.

摘要： A rotary electric machine includes a stator with a stator winding, a rotor with a field winding supported for rotation about a rotation axis relative to the stator, and an excitation winding. The excitation winding is fixed relative to the rotor and is electrically connected to the field winding. The rotor defines a coolant channel having an inlet and an outlet. Liquid coolant enters the inlet and flows outwardly through a portion of the excitation winding to conduct heat away from the excitation winding. Generators, aircraft electrical systems, and methods of cooling rotary electric machines are also described.

摘要： A rotor drive generator drive gear for an integrated drive generator can include an annular body having an outer diameter and an inner diameter defining an inner diameter channel through the body in a direction of an axis of rotation of the annular body. The annular body can define a gear defined on the outer diameter of the annular body and a bearing race defined on the outer diameter of the annular body. The bearing race can include a bearing race channel and one or more race relief channels defined from the bearing race channel at least partially inwardly toward the inner diameter channel. One or more lubrication conduits are defined through the body to fluidly connect the inner diameter opening and the bearing race such that lubricant can travel from the inner diameter channel to the bearing race for providing lubrication to a bearing assembly disposed in the bearing race.
