摘要： A rotating electric machine system is equipped with a rotating electric machine including a rotating shaft and a permanent magnet, and a housing in which the rotating electric machine is accommodated. A bearing is interposed between the housing and the rotating shaft. The bearing is retained by a hollow tubular shaped bearing holder. The bearing holder includes a cover member that covers the bearing from an outer side in a diametrical direction of the rotating shaft. An insulating element is interposed between an outer circumferential surface of the bearing and an inner circumferential surface of the cover member.

摘要： A racking device for remote operation of a circuit breaker or transfer switch comprising: a motor and gear box operatively attached to a racking adapter and an adjustable anti-rotation device affixed to the motor and gear box of the racking device. The adjustable anti-rotation device configured to engage a racking mechanism access window and/or a circuit breaker or transfer switch panel, wherein at least one plane of the anti-rotation device is substantially parallel with at least one plane of the racking mechanism access window and/or the circuit breaker or transfer switch panel and move the anti-rotation device substantially along an x-axis and/or a y-axis of the racking screw access window and/or a circuit breaker panel to compensate for a misalignment or dimensional variances between the racking adapter of the racking device and the racking mechanism of the circuit breaker or transfer switch. Methods of using the racking device are also disclosed.

摘要： The present invention can provide a pinion-equipped motor that has a shaft provided with a pinion having a perfect tooth shape portion functioning as a gear, wherein to shorten the length of the pinion in the axial direction, the perfect tooth shape portion of the pinion can be offset to the proximal side of the shaft. In this pinion-equipped motor that has a shaft provided with a pinion on the distal side, the pinion has: a base portion that is mounted on the shaft; a perfect tooth shape portion that has an outer diameter equal to or smaller than that of the shaft and functions as a gear; and an imperfect tooth shape portion which is provided between the base portion and the perfect tooth shape portion, the length in the shaft axial direction of which is equal to or smaller than that of the perfect tooth shape portion in said direction, and which does not function as a gear.

摘要： A frame of an electric motor has inlet holes to allow ambient air to flow into an inside of the motor and outlet holes to allow the ambient air entering through the inlet holes to flow out to an outside of the motor. The motor includes a shaft, a rotor, a stator, a fan to rotate integrally with the shaft, and a guide. The guide is disposed outwardly of the fan in the radial direction and has a shape for suppressing foreign materials contained in the ambient air entering through the inlet holes from coming into contact with the stator and the rotor.

摘要： A power tool is provided including a tool housing including a motor housing and a handle portion; a battery receptacle disposed at an end of the handle portion opposite the motor housing, the battery receptacle being configured to receive a battery pack; and a brushless DC motor including a stator and a rotor. The stator includes a stator lamination stack, an end insulator, and input terminals supported by the end insulator. A power circuit board is coupled to the input terminals to supply power to the motor. The motor produces a maximum power output of at least 1600 watts for driving an output shaft at a maximum torque of at least 30 inch-pounds and a maximum speed of at least 8000 rotations-per-minute.

摘要： A solenoid actuator 1 includes: a coil 3; a first stator 10 and a second stator 20 disposed with an air gap 11 therebetween in an axial direction so as to form a magnetic path 4 around the coil 3; and a mover 50 configured to be movable in the axial direction to a maximum stroke position (X=Xmax) from an original position (X=0) on a radially inner side of the first stator 10 toward the second stator 20 by a magnetic force generated by energizing the coil 3. The mover 50 has an annular projection 100 projecting in the axial direction from a peripheral edge portion of the mover 50. The second stator 20 includes: a second yoke 24; and a second press part 40 made of a magnetic material and disposed on an inner peripheral side of the second yoke 24 so as to at least partially form an annular recess 120 for receiving the annular projection 100 of the mover 50 at the maximum stroke position (X=Xmax).

摘要： An electrical machine includes a stator assembly coupled to an engine stator component of a propulsion engine. The stator assembly includes a stator support assembly fixedly attached to the engine stator component and a stator disposed on a supporting surface of the stator support structure. The electrical machine also includes a rotor assembly including a rotor support structure connected to a shaft of the propulsion engine and a rotor attached to the rotor support structure such that the rotor is disposed radially inward of the stator. The rotor exchanges rotational energy with the shaft to operate as either an electrical motor or an electrical generator.
