Abstract
The invention relates to a cylindrical eddy-current permanent magnetic coupling, which comprises a cylindrical conductor rotor and a cylindrical permanent magnetic rotor. The cylindrical conductor rotor is mounted on a motor shaft, and consists of a yoke and a conductor, and the material of the conductor is copper or aluminum; the cylindrical permanent magnetic rotor is mounted on a load shaft, and consists of a cylindrical rotor body, a magnetic holder and a permanent magnet; and the cylindrical permanent magnetic rotor is arranged in the cylindrical conductor rotor. Torque is transmitted by the interaction between an induced magnetic field generated by the rotating conductor rotor cutting lines of magnetic induction and a permanent magnetic field.
Description
Technical field
The present invention relates to a kind of permanent magnetism drive technology, a kind of specifically cylindrical eddy-current permanent magnetic coupling.
Background technology
ISBN 7-5025-5083-6 Drive Technology and equipment one book that the Chemical Industry Press of being write by Mr. Zhao Kezhong publishes have been introduced a kind of drum type brake magnetic coupling, and it is by inside and outside two magnetic conductors and three partial component such as separation sleeve that are provided with in driving and driven magnet rotor that watt shape permanent magnet on it forms and the working gas gap between active and driven magnet rotor are set form.Outer magnetic cylinder is the active magnetic rotor, is installed on the motor shaft.Interior magnetic cylinder is driven magnet rotor, is installed on the bearing axle.
When motor drives active magnetic rotor rotates, realize the synchronous rotation of two building blocks by the mutual magnetic torque (or magnetic field force) that produces of permanent magnet in the inside and outside magnet rotor.
Above-mentioned permanent magnetic coupling is a tubular synchronous mode permanent magnetic coupling.The invention provides a kind of cylindrical eddy-current permanent magnetic coupling.
Summary of the invention
The invention provides a kind of cylindrical eddy-current permanent magnetic coupling, it is made up of a cylindrical conductor rotor and a tubular p-m rotor; Cylindrical conductor rotor links to each other by air gap (abbreviation air gap) with the tubular p-m rotor, around axis rotation separately; P-m rotor places in the conductor rotor.
Cylindrical conductor rotor is made up of yoke and conductor, is installed on the motor shaft, and conductor material is copper or aluminium.
The tubular p-m rotor is made up of cylindrical rotor body, magnetic support and permanent magnet, is installed on the bearing axle.
Operation principle is: motor and cylindrical conductor rotor are rotated synchronously, cylindrical conductor rotor and tubular p-m rotor produce relative motion, thereby produce eddy current on the conductor, form induced field, induced field and permanent magnetic field interact, thereby drive p-m rotor along and the equidirectional rotation of conductor rotor, the result is that transmission of torque with motor shaft is to bearing axle.
The invention provides a kind of cylindrical eddy-current permanent magnetic coupling, its beneficial effect is:
Can be applicable to widely in the motor driving system, particularly in centrifugal fan and pumping system, can play the soft start effect, can isolate the vibration between motor and the load simultaneously, increase the reliability of dragging system.
Description of drawings
Fig. 1 is the sectional side elevation of a kind of cylindrical eddy-current permanent magnetic coupling of the present invention.
Embodiment
With reference to accompanying drawing 1:
Cylindrical conductor rotor 1 is made up of yoke 2 and conductor 3, is installed on the motor shaft 4, and conductor 3 materials are copper or aluminium.
Cylindrical conductor rotor 1 links to each other by air gap 7,7 ' with tubular p-m rotor 5, around axis rotation separately; P-m rotor 5 places in the conductor rotor 1.
Operation principle is, motor and cylindrical conductor rotor 1 are rotated synchronously, cylindrical conductor rotor 1 produces relative motion with tubular p-m rotor 5, thereby produce eddy current on the conductor 3, form induced field, induced field and permanent magnetic field interact, thus drive p-m rotor 5 along and conductor rotor 1 equidirectional rotations, the result is that transmission of torque with motor shaft 4 is to bearing axle 6.
