Embodiment Construction

[0023] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] see Figure 4 As shown, the electromagnetic coupling excitation governor 30 of the present invention is basically the same as the electromagnetic slip clutch 10 of the prior art, and is also connected between the motor 1 and the load, including a casing 31 and an external rotating shaft arranged in the casing 31. The body 32 , the inner rotating body 33 arranged in the outer rotating body 32 , and the field winding 34 wound on the inner rotating body 33 . Please combine Figure 5 ~ Figure 7 As shown, the difference is that the external rotating body 32 has a cylindrical structure as a whole, and is formed by stacking silicon steel sheets. One end of the external rotating body 32 is connected to the output shaft 2 of the motor 1, and the inner rotating body 32 A plurality of guide bar grooves 321 are evenly formed on t...

Abstract

The invention discloses an electromagnetic-coupling excitation speed regulator. The speed regulator is connected between a motor and a load, and comprises an outer rotator, an inner rotator and excitation windings. The inner surface of the outer rotor is uniformly provided with a plurality of conducting bar grooves in the axial direction, a squirrel cage conducting bar is arranged in the conducting bar groove, and a closed loop is formed by the squirrel cage conducting bars through end rings. The outer surface of the inner rotator is provided with a plurality of winding grooves, and the excitation windings are arranged in the winding grooves between magnetic poles. When the excitation windings are energized, the outer surface of the inner rotator generates a plurality of pairs of magnetic poles with N and S alternation, while the outer rotator and the inner rotator rotate together after electromagnetic coupling, and the excitation current is changed, thereby regulating the speed. The invention reduces the excitation consumption, enhances the transmission efficiency, is simple in structure and assembly, has no harmonic pollution on networks, prolongs the service life, and decreases the cost.

Description

technical field [0001] The invention relates to the speed regulation technology of electric motors, and more specifically relates to an electromagnetic coupling excitation speed governor, which can reduce energy consumption and improve transmission efficiency. Background technique [0002] Since the advent of AC asynchronous motors, many scientific and technological workers have made unremitting efforts to realize simple, economical, reliable and efficient speed regulation technology. Slip clutches appeared as early as the 1960s, and later developed into electromagnetic speed-regulating motors. From that time, it mainly solved the problem of a wide range of speed regulation, but failed to take into account the problems of energy consumption and efficiency. refer to figure 1 , figure 2 As shown, the electromagnetic variable speed motor 10 includes an electromagnetic slip clutch 11 and a squirrel-cage asynchronous motor 1. The electromagnetic slip clutch 11 includes an out...
