Abstract

The invention discloses a motor with a slotless amorphous iron alloy radial magnetic circuit. A stator core (21) is wound into a cylinder by an amorphous iron alloy strip; a stator winding (22) is wholly cylindrical and is fixed on a cylindrical surface in the stator core (21); a metal reinforced bushing (25) is fixed on an inner wall of the stator winding (22); and a radial air gap (5) is formed between an inner hole of the stator winding (22) and an outer surface of a rotor (3). A rotor core (31) is made of an amorphous iron alloy material to form a hollow columnar structure; a key slot (312) which is connected with a motor shaft (6) is formed on an inner hole wall; a radial outer surface of the key slot (312) is matched with a permanent magnet (32); and the permanent magnet (32) is embedded in or sleeved on an outer surface of the rotor core (31) for fixation. The motor effectively reduces the volume, reduces the loss, improves the efficiency, simultaneously avoids processing difficulty of slots, saves working hours, greatly reduces the processing cost, eliminates motor slot effect, reduces electromagnetic noise, has the advantages of low eddy-current loss, excellent high-frequency characteristics and high power density, and is a high-efficiency and energy-saving motor.

Description

【Technical field】 [0001] The present invention relates to magnetic circuit components for motor manufacturing, and in particular to stator or rotor bodies characterized by armature windings and magnetic materials. 【Background technique】 [0002] Amorphous iron alloy material is an alloy material with a long-range disordered structure formed by using the metal atoms in the active state in the high-temperature molten state to be arranged in an orderly manner in a certain crystal state during rapid cooling. Compared with traditional silicon steel materials, this amorphous iron alloy material has a series of advantages such as high magnetic permeability, high resistance, small eddy current loss and excellent high-frequency characteristics, but its processing characteristics are poor, and it is difficult to punch into sheets and process large volumes. Machining. The prior art motor includes a generator and an electric motor, including a casing, an end cover, a stator, a rotor an...
