Abstract: A rotating electrical machine includes a frame, and a stator core fixed to an inner peripheral surface of the frame and including a plurality of split cores disposed in a peripheral direction. Each of the plurality of split cores includes a groove disposed along an axial direction on a central position in the peripheral direction on an outer peripheral surface of the split core, and a first protrusion disposed on a bottom of the groove and protruding outward in a radial direction.

Abstract: A rotor includes a rotor core; and first and second permanent magnets arranged in the core such that each of the first magnets corresponds to one of the second magnets and, on a cross-sectional plane of the rotor core perpendicular to a rotation axis thereof, a first line passing through the first magnet and a second line passing through the second magnet meet at a point pointing toward the rotation axis. The first and second magnets are arranged such that a straight line interconnecting the rotation axis and the point is interposed therebetween, an angle of the first magnet relative to the straight line being smaller than that of the second magnet relative to the straight line, and a width of the first magnet in the direction parallel to the first line being smaller than that of the second magnet in the direction parallel to the second line.

Abstract: A rotating electrical machine includes a plurality of core pieces forming a stator core. Each of the core pieces includes contact surfaces on one side end and another side end in a peripheral direction, a tapered protrusion on the contact surface of the one side end, the protrusion including first inclined surfaces outside and inside, and a recess on the contact surface of the other side end, the recess including second inclined surfaces contacting the first inclined surfaces outside and inside to receive the protrusion of adjacent core piece. A cross-sectional shape of the protrusion is a shape such that, inside a circle centered on a first end portion with a distance being a radius between a second end portion located on an opposite side of the first end portion and the first end portion, at least a part of the first inclined surfaces contact the second inclined surfaces.

Abstract: An actuator in accordance with an embodiment includes at least one linear motor, a partition member and a fan. The linear motor is configured to linearly move a shaft serving as a movable member. The partition member is provided close to the shaft and configured to partition a space defined between the shaft and a control board for controlling the linear motor. Further, the fan is arranged on the side of the shaft with respect to the partition member and configured to flow an air existing in a partitioned space on the side of the shaft.
