摘要： In the embodiment described in the specification, a fault tolerant motor drive circuit arrangement includes a motor having three stator windings which are electrically isolated and are supplied by separate single phase drive circuits, each having a differential current sensor detecting current in both circuit conductors and an overcurrent sensor in one circuit conductor, along with a ground connection for each circuit having a ground conductor with an overcurrent sensor and a high resistance with a voltage sensor across the high resistance. A monitoring unit receives signals from all of the differential current sensors, overcurrent sensors and voltage sensors to provide indications of the location of insulation faults or incipient faults in the windings.

摘要： In the parallel resonant DC link inverter described in the specification, a DC voltage is applied to a plurality of semiconductor switches to provide an AC driving voltage for an AC motor by way of an LC tank circuit containing a nonlinear capacitance device having an antiferroelectric material as its dielectric. As a result of the increase in capacitance with increased voltage, the voltage peak of the link voltages produced by the circuit is reduced without a corresponding reduction in the volt-second product applied to the motor load.

摘要： A controllable pitch propeller arrangement includes a plurality of propeller blades (12) supported from a central hub (14) which is rotatably mounted on a shaft in which each blade is pivotally supported from the central hub. Two radial pins (20, 22) extending from the outer ends of each of the blades (12) are received in corresponding rims (38, 36) having peripherally disposed permanent magnet arrays. The rims (38, 36) are rotated to drive the propeller by energization of coils in a stator assembly (44) surrounding the rims and the pitch of the blades is changed by changing the phase relationship of the current supplied to the stator coils (48, 50) to change the angular relation of the rims (38, 36).

摘要： In the embodiments described in the specification a metal heat transfer cold plate has two sets of parallel coolant passages extending between opposite end surfaces and non-metallic headers made of electrically insulating material are attached to the opposite ends of the metal plate. One of the headers provides an inlet to one set of coolant passages and an outlet from the other set of coolant passages and the other header provides fluid communication between the two sets of coolant passages. The headers are affixed to the cold plate by adhesive or by a snap-in connection having a sealing gasket between each header and the cold plate and the assembled cold plate and headers are insulatively supported by mounting feet attached to the electrically insulating headers.

摘要： A high voltage, single-stage variable speed motor power supply utilizes direct AC-to-AC converters that do not have any intermediate DC link, along with a multi-level, multi-phase, multi-circuit variable speed motor drive and a motor in which a stator is wound with a number of multi-phase circuits. Each multi-phase circuit includes semiconductor switches arranged in drive switch pairs which are operated to produce an imaginery DC supply with the switches being controlled so that the most positive line-to-line source voltage is utilized for the inversion process.

摘要： A combined steam condenser and liquid-to-liquid heat exchanger (90) has an outer shell (92) forming an enclosure within which a second plurality of tubes (100) are supported at opposite ends by tube sheets (102) to provide a steam condenser. Within the outer shell an inner shell having a heat exchange liquid inlet and outlet contains a first plurality of tubes providing a heat exchanger. In one embodiment a first head (126) is affixed to one end of the outer shell (92) and cooling liquid introduced into that head passes through the first plurality of tubes (108) and part of the second plurality of tubes (106) to a second head (122) at the opposite end which directs the cooling liquid through an upper portion of the second plurality of tubes (106) back to the first head. The cooling liquid is then directed from the first head through a lower part (110) of the second plurality of tubes towards the second head where it is discharged through an outlet. Steam received at a steam inlet in the top of the outer shell passes over the second plurality of tubes on which it is condensed and the resulting condensate falls into a condensate collection hot well (96) having a condensate removal outlet at the bottom of the outer shell. In another embodiment Ushaped tubes are provided in both the first and second pluralities and the cooling liquid is introduced and removed from the same head at one end of the outer shell.
