Abstract: A transmission mechanism device includes a transmission mechanism including a hollow shaft, and a bearing supporting an outer face of the shaft. A holder holding the bearing is on the inner face of a housing of the transmission mechanism. The holder has a facing face facing an end of the shaft, a tubular portion holding the bearing and protruding in the axial direction radially from the facing face, and a rib inside the tubular portion and protruding in the axial direction from the facing face. The rib extends in a concave shape opening upward. A lower end of an inner face of the rib is below an upper end of an inner face of the shaft when viewed from the axial direction. At least one end of the rib in an extending direction faces an inner face of the tubular portion via a gap when viewed from the axial direction.

Abstract: A submersible pump electrical motor has a bearing hub between adjacent rotor sections. The bearing hub has a hub outward facing sidewall and a hub inward facing hub sidewall through which the shaft extends. A collar having a collar inward facing sidewall is rigidly mounted to the hub outward facing sidewall. The collar has a collar outward facing sidewall spaced from stator sidewall by an annular clearance. A slit in the collar extends from the collar inward facing sidewall to the collar outward facing sidewall. An anti-rotation spring has a supporting portion inwardly biased against the hub outward facing sidewall and a locking portion protruding outward through the slit into engagement with the groove to prevent rotation of the hub and the collar.

Abstract: Provided are a slim-type stator using a multilayer printed circuit board (PCB) in which a coil pattern is patterned on an uppermost PCB layer and a sensing coil pattern for detecting a rotor rotation position is integrally formed in a margin of the uppermost PCB layer, to thereby realize sensorless driving simply, and a sensorless single-phase motor using the slim-type stator, and a cooling fan using the sensorless single-phase motor. The slim-type stator includes: a multilayer PCB; a coil pattern patterned on respective PCB layers of the multilayer PCB and connected through throughholes; and a sensing coil pattern formed on an uppermost PCB layer to detect a rotor rotation position, wherein the sensing coil pattern is positioned and set at a position deviated from a magnetic pole interface of a rotor that is positioned and set by a dead point prevention yoke when the rotor is in an initial state.
