Embodiment Construction

[0021] Referring to the accompanying drawings, the slotless asynchronous motor described in the embodiment includes a stator and a rotor. The rotor includes a rotating shaft 1 supported on two left and right end covers 11 through bearings 12. The left and right end covers 11 are fixed by end cover fixing bolts 10. The rotating shaft 1 is covered with a pulley 2 and two pole plates 3 inherently used as power output. The rotating shaft 1 is cylindrical and stepped, the middle section between the two pole disks 3 is the thickest, and the two end sections are the thinnest. On the middle section of the rotating shaft 1 located between the two pole disks 3, there are inherent fan blades 15, each of the rotor A pole plate 3 includes 8 magnetic poles 6 arranged radially and evenly, the inner section of each magnetic pole 6 is closely adjacent, and the outer section is a thickened trapezoidal surface. There are ventilation holes 16, and each magnetic pole 6 is superimposed and fixed to...

Abstract

The invention relates to a slot-less asynchronous electric motor, which includes a stator and a rotor, the rotor includes a rotary shaft, which is covered with two polar plates, the stator includes a stator iron core and the stator coil winded on the stator iron core, each plate of the rotor includes even magnetic polar arranged with radiating shape evenly, each magnetic polar is connected together with several pieces of cool rolling high silicon orientation silicon steel plates, each plate is produced according to the orientation direction, each magnetic polar is winded with rotor coil, the winding directions of the rotor of the joined magnetic polar are reverse, the quantity of the stator iron core is the integer times of 3 which is the quantity of the magnetic polar, the stator iron cores are arranged along the circle evenly, and fixed in the slots of the two ring plate, each stator iron core is connected together with several pieces of cool rolling direction silicon steel plates, each piece of cool rolling orientation silicon steel core is produced with the orientation direction, there has a gap between each magnetic polar and the stator iron core. The efficiency of the asynchronous electric motor is upgraded about 8%-10% compared with the universal Y series asynchronous electric motor, and the utilization rate of the material is upgraded greatly.

Description

technical field [0001] The invention relates to an asynchronous motor, more specifically a slotless asynchronous motor. Background technique [0002] Asynchronous motors have a history of more than 100 years since they came out, and are widely used in various industries. At present, all asynchronous motors are slotted motors, and the common type is the Y series asynchronous motor. This general-purpose slotted asynchronous motor includes two parts, the stator and the rotor. The stator core is made of laminated low-silicon silicon steel sheets. Several grooves must be punched on each laminated sheet, and the grooves are embedded with The stator coil, the rotor shaft is fitted with rotor poles made of laminated low-silicon silicon steel sheets, and the rotor poles are wound with rotor coils. Although the efficiency of this general-purpose asynchronous motor is higher than that of the eliminated JO 2 The series of asynchronous motors have been improved, reaching 88%, but beca...
