Example Embodiment

[0031] like figure 2As shown, the modular coreless permanent disk motor stator of the present invention has more than two fan-shaped stator winding modules 4 butt-connected and installed to form a stator winding disk 5 . Each segmented stator winding module 3 includes a segmented stator winding 2 and its corresponding part of the motor housing 3 . It is characterized in that the fan-shaped stator winding is composed of one or more coils 1, and each coil is formed by winding a wire 6 in a certain way. The coils 1 can be arranged in a single layer or double-layered cross arrangement. The traditional The coil arrangement of the whole coil of the coil is applicable here. Part of the motor casing 3 corresponding to the sector stator winding 2 is located outside the sector stator winding 2, and is on the same plane perpendicular to the motor shaft 13 as the sector stator winding 2, and all the sector stator windings have the same central angle. A segmented stator winding 2 is fix...

Abstract

The invention discloses a non-iron-core permanent disc type motor stator which comprises a stator winding disc (5), wherein the stator winding disc (5) is composed of multiple fan-shaped stator winding modules (4) in a butt joint mode. Each fan-shaped stator winding module (4) comprises a fan-shaped stator winding (2) and a corresponding motor shell portion (3), wherein the motor shell portion (3) and the fan-shaped stator winding (2) are located on the same plane which is perpendicular to a rotating shaft of a motor (13). The more than two fan-shaped stator winding modules (4) are combined into the stator winding disc (5), and two ends of a copper column (8) are inserted into connecting holes (9) in every two adjacent fan-shaped stator winding modules (4) and connected with wires (7) on the end portions of the stator windings. When the non-iron-core permanent disc type motor stator is assembled, the more than two fan-shaped stator winding modules (4) are inserted in a butt joint mode into an air gap formed between every two adjacent rotor magnetic steel discs (11), and then the assembling of the overall stator winding disc (5) is finished.

Description

technical field [0001] The invention relates to a stator structure of a disc motor, in particular to a modular stator winding disc structure suitable for a coreless permanent disc motor and an assembly method thereof. Background technique [0002] The permanent disk motor has a flat shape and is mainly composed of a stator and a rotor. Usually, the stator is a winding disk, and the rotor is glued with multiple permanent magnet disks arranged alternately in N and S polarities. The stator and the rotor are respectively several ring-shaped disk structures, the stator disk and the rotor disk are placed perpendicular to the motor shaft, and the stator winding disk and the rotor magnetic steel disk are alternately installed on the rotating shaft during installation. The winding of the disc motor is shaped by winding elements and poured into the disc winding insulating material to form the entire circular stator winding disc. The permanent disk motor has no excitation loss due to ...
