Embodiment Construction

[0013] The teaching demonstration device for an asynchronous motor of the present invention will be described in detail below on the basis of the accompanying drawings. The asynchronous motor teaching demonstration device of the present invention is completed by transforming the existing asynchronous motor. The asynchronous motor teaching demonstration device comprises a front end cover (1), a stator (2), a lead wire (3), a rotor (4), a rear end cover (5) and a rotating shaft (6). The difference from the existing asynchronous motor is that in addition to the rotor (4), the rotating shaft (6) is also provided with a synchronization indicator, and the front end cover is an end cover with a small number of spoke structures, while the traditional end cover Both are disc-shaped sealed structures that cannot be seen from the outside at all, while the front end cap of the present invention has a small number of spokes (such as image 3 ), such as three, since the rest are empty, the...

Abstract

A teaching demonstration device for an asynchronous motor, comprising a front cover (1), a stator (2), a lead wire (3), a rotor (4), a rear end cover (5) and a rotating shaft (6), the rotating shaft (6) is provided with Outside the rotor (4), there is also a synchronous indicator (7), and the front end cover (1) is a structure with a small number of spokes or a transparent end cover, so that the internal structure of the stator can be clearly seen from the outside, wherein the synchronous indicator (7) includes a bearing sleeved on the rotating shaft (6) and a magnet on the bearing, wherein the rotor (4) and the synchronous indicator (7) are located inside the stator (2), and the size of the synchronous indicator (7) It is not larger than the rotor (4), and there are indicator marks on both the rotor (4) and the synchronous indicator (7). The synchronous indicator (7) is closer to the front end cover (1) than the rotor (4), so that through The front cover (1) can clearly see the rotation of the rotor (4) and the synchronization indicator (7) from the outside.

Description

technical field [0001] The invention relates to an asynchronous motor teaching demonstration device, which belongs to the field of teaching aids. Background technique [0002] In the teaching of high school physics, university physics and electric power departments, many of them will involve the teaching of asynchronous motors. Asynchronous motor belongs to a kind of machine commonly used in physics and electricity, and its composition structure and operation principle belong to a technology known in the art, such as figure 1 As shown, the asynchronous motor generally includes a front end cover (1), a stator (2), a lead wire (3), a rotor (4), and a rear end cover (5), wherein the rotor is arranged on the rotating shaft (6). The rotor (4) is arranged inside the stator (2), and both ends are sealed and assembled by front and rear end covers. From the outside, it seems that this is an overall airtight device, and the working conditions inside cannot be seen from the outside. ...
