摘要： An exciter comprises a stator armature (144) defining a plurality of circumferentially spaced apart winding slots (148) separated by respective stator teeth (150). first exciter winding (134) with multiple phases, a second exciter winding (136) with multiple phases. The individual windings of the first and second exciter windings are seated in the winding slots. For each phase of each of the first and second exciter windings there are two leads configured to connect to a generator control unit (104) (GCU).

摘要： An electric motor system (100) implements a redundant wye-wounded motor (104) that includes first phase leads (112), second phase leads (114), first neutral leads (116), and second neutral leads (118). The first and second phase leads (112, 114) receive alternating current (AC) power from a power supply. A first phase-lead switch (111) selectively connects the first phase leads (112) to the power supply, and a second phase-lead switch (113) selectively connects the second phase leads (114) to the power supply. A first neutral-lead switch (115) selectively connects the first neutral leads (116) to the redundant wye-wounded motor (104), and a second neutral-lead switch (117) selectively connects the second neutral leads (118) to the redundant wye-wounded motor (104). A controller (110) detects a circuit fault among a plurality of different types of circuit faults, and controls the operation of one or both of the primary neutral-lead switch (115) and the second neutral-lead switch (117) based on the circuit fault.

摘要： An auxiliary power unit (APU) generator system (100) for an APU can include a doubly-fed induction generator (DFIG) (103) configured to be operatively connected to an APU to be turned by an APU and to have an output frequency that is a function of an excitation frequency and an APU speed. The system can include a generator control module (105) configured to control the excitation frequency to the DFIG to output a substantially constant frequency with changing APU speed to supply the substantially constant frequency to a load.

摘要： A system can include a first generator (101) configured to operate in a first speed range to produce a predetermined output characteristic, a second generator (103) configured to operate at a second speed range different from the first speed range to produce the predetermined output characteristic, and a controller (105) configured to activate the first generator at and/or above a first low activation speed and at and/or below a first high activation speed within the first speed range. The controller can be configured to activate the second generator at and/or above a second low activation speed within the second speed range. The controller can be configured to deactivate the first generator at and/or above a first high deactivation speed. The controller can be configured to deactivate the second generator at and/or below a second low deactivation speed.

摘要： A generator arrangement includes a stator (104) with armature winding (106), a rotor (108) with one or more permanent magnets (110) supported for rotation relative to the stator, a variable speed drive (112), and a control module (114). The variable speed drive is connected to the rotor for rotating the rotor within a predetermined speed range. The control module is disposed in communication with the armature windings and is operatively connected to the variable speed drive to maintain constant output voltage as load changes by varying rotational speed of the rotor.

摘要： An electrical machine system includes a stator (102) having a conical stator surface defining a rotary axis. A rotor (104) is operatively connected to the stator for rotation relative thereto, wherein the rotor incudes a conical rotor surface. A conical gap (106) is defined between the conical surfaces of the stator and rotor about the rotary axis. An actuator (108) is operatively connected to at least one of the stator and rotor for relative linear motion along the rotary axis of the stator (102) and rotor (104) to change the conical gap (106), wherein the actuator (108) provides relative linear motion between a first position for a first conical gap width and a second position for a second conical gap width different form the first conical gap width. In both the first and second positions the full axial length of one of the rotor or stator is axially within the axial length of the other.
