Abstract

The invention relates to a barrel-type electromagnetic speed regulation system, which comprises an inner barrel rotor, an outer barrel rotor, conductive slip rings, electric brushes and a DC power supply, wherein the inner barrel rotor is arranged at an input shaft end; the outer barrel rotor is arranged at an output shaft end; the inner barrel rotor and the outer barrel rotor are coaxially nested; the inner barrel rotor is provided with soft magnets of which each is provided with a coil; positions, corresponding to the soft magnets, on the outer barrel rotor are provided with permanent magnets; the input shaft is provided with the conductive slip rings which are matched with the electric brushes; the electric brushes are connected with the anode and the cathode of the DC power supply; the conductive slip rings are connected with the coils by lead wires; and the coils wound by the circumferentially adjacent soft magnets arranged on the inner barrel rotor rotate in opposite directions, while the coils wound by the axially adjacent soft magnets are in the same direction. The barrel-type electromagnetic speed regulation system has the advantages that: the soft magnets on the inner barrel rotor reduce demagnetization and realize control over a rotation speed of the output shaft; and the barrel structure can generate strong electromagnetism, and the areas of the permanent magnets are great, so working efficiency is improved.

Description

technical field [0001] The invention relates to the field of industrial control, in particular to a cylindrical electromagnetic speed regulating system. Background technique [0002] At present, variable frequency speed regulation is widely used in industrial sites. The output speed of the motor is controlled by controlling the input frequency of the motor. The price is relatively expensive, and the structure and operation are complicated. It affects communication and has high requirements on the environment, so it is not suitable for working in harsh environments. With the development of science and technology, the permanent magnet coupling speed control system came into being. It changes the output torque by adjusting the air gap between the permanent magnet and the copper disc, so as to achieve the purpose of speed regulation. The defects of this type of magnetic coupling system are: the magnet is small in size, the torque generated is small, and the speed regulation ra...
