An electric motor with a stator and an axle (20). The stator has a laminated stator core (10) formed from a multitude of individual teeth (11). At least some of the individual teeth (11) each have a radially inner pressing portion (13) for elastic and/or plastic deformation and establishment of a press-fit connection between the laminated stator core (10) and the axle (20). The stator is fixed to the axle (20) through the deformation of the pressing portions (13) and a force acting on the axle (20). At least one securing element (30) is on at least some of the pressing portions (13) to transmit a torque between the axle (20) and the laminated stator core (10) and fix the position of the laminated stator core (10) relative to the axle (20) in the circumferential direction (U).

Systems and methods relate to a vertical takeoff and landing (VTOL) platform that can include a stator and a rotor magnetically levitated by the stator. The rotor and stator can be annular, such that the rotor rotates about a rotational axis. The stator can include magnets that provide guidance, levitation, and drive forces to drive the rotor, as well as to control operation of rotor blades of the rotor that can be independently rotated to specific pitch angles to control at least one of lift, pitch, roll, or yaw of the VTOL platform. Various controllers can be used to enable independent and redundant control of components of the VTOL platform.

A stator core is integrally moulded with an insulator employing an insulating resin material, together with a fixed shaft which is inserted into a centre hole in a core back portion, and the stator core and a motor circuit board are assembled as a single piece by mating a plurality of circuit board insertion pieces protruding on an axial end of the insulator on the opposite side to an output end with circuit board insertion holes.

Electric compressor 1 has electric motor 10 housed in casing 40, the motor including stator 2 having yoke portion 2a and plural tooth portions 2b, and rotor 3 disposed radially inside stator 2. Protrusion 41f protrudes at plural circumferential positions of inner periphery 41a1 of casing 40, which has protruding end surface 41f1 contacting an outer periphery of yoke portion 2a with width larger than tooth portion 2b. Contact tooth back portion 2a11 contacts protruding end surface 41f1, out of plural tooth back portions 2a1 each disposed behind tooth portion 2b as part of the outer periphery of yoke portion 2a, is formed in a region except both edge portions 41h of protruding end surface 41f1 in a circumferential direction within a circumferential angle range θ in which the protruding end surface 41f1 is located.

The present invention relates to an in-wheel motor driving apparatus for reducing weight, improving Hall sensor assembly performance, and reducing a defect rate.
