In an electric power unit which accommodates at least an electric motor in a housing, polygonal rib regions in which polygonal ribs are respectively formed are provided on at least two surfaces of an outer peripheral surface of the housing, and the polygonal rib regions are connected by a circumferential rib. Here, a first axial rib and a second axial rib extending parallel to an axial direction are formed on the outer peripheral surface of the housing, and the polygonal rib region is provided in a portion sandwiched between the first axial rib and the second axial rib. Further, the circumferential rib is formed over the entire part of the polygonal rib region in a circumferential direction. Note that the polygonal rib is a honeycomb rib.

Electric power unit

A ducted fan that includes a housing with a cylindrical shape, a ring motor in the housing, and fan blades extending radially inward from an inner circumferential surface of the ring motor. The housing includes a first housing that covers a first side in an axial direction of the ring motor and a second housing that covers a second side in the axial direction of the ring motor. The second housing includes through holes penetrating the second housing at a portion on the second side in the axial direction with respect to the ring motor. The housing includes an outer circumferential wall including first and second wall portions located in outer circumferential portions of the first and second housings. The outer circumferential wall includes opening portions defined by a gap between the first and second wall portions.

Ducted fan

A motor includes a rotor, a stator, and a support member. The rotor includes a rotor magnet, a magnet holding portion, and spoke portions. The stator includes a plurality of coils and a stator core. The support member includes a stator holding portion and a mount portion. The mount portion includes a plurality of slits extending radially inward from a radially outer end portion of the mount portion. The slits each have openings in an outer circumferential end and an upper surface of the mount portion. The openings of the slits positioned in the upper surface of the mount portion are positioned between the coils adjacent to each other in the circumferential direction when viewed in the axial direction.

Motor and rotor blade apparatus

A motor assembly includes a motor including a rotor that rotates about a motor axis, a transmission that transmits motive power of the motor to an axle, a housing that accommodates the motor and the transmission, and an oil pump fixed to the housing. The housing includes a tubular motor housing extending along the motor axis, and the motor housing includes a rib on a side surface facing the oil pump. The rib protrudes to a radially outer side from the side surface, and has a plate shape extending along the motor axis.

Motor assembly

In an aspect of the motor of the present invention, the motor includes a shaft centered on a center axis extending in a predetermined direction, and a stator located radially outside of the shaft. The stator has a coil wound around the stator. The motor further includes a housing member having a substantially cylindrical shape with a bottom, where the housing member accommodates substantially the entire stator, and supports the shaft, a cooling medium with which the housing member is filled, where the stator and the coil is immersed in the cooling medium, and a rotor that rotates radially outside of the housing member with the center axis of the shaft as a rotation center.

Motor

Provided is a compound represented by the following formula (I) or a pharmaceutically acceptable salt thereof: [in the formula, Rto R, A, and *1 to *3 are as defined in Description].
