Product Overview

Permanent magnetic coupling is a contactless force transmission device, which transmits power from one rotating part to another rotating part through the attraction of magnets without any physical connection between the two parts.
There are 2 main types of magnetic drive couplings: flat permanent magnetic couplings and coaxial magnetic couplings.
Working Principle: Coaxial permanent magnetic coupling consists of outer magnet, inner magnet and isolation sleeve. The inner and outer magnets are composed of permanent magnets magnetized along the radial direction and magnetized in the opposite direction, the permanent magnets are arranged alternately along the circumference with different polarities and fixed on the mild steel steel ring to form a magnetic circuit breaker.         
The isolation sleeve is made of non-ferritic high-resistance materials, generally austenitic stainless steel. At rest, the outer magnet of the N pole (S pole) and the inner magnet of the S pole (N pole) attract each other and into a straight line, at this time the torque is zero. When the outer magnet is rotating under the drive of the power machine, at first the inner magnet is still at rest due to friction and resistance of the driven parts, at this time the outer magnet starts to offset a certain angle relative to the inner magnet, due to the existence of this angle, the outer magnet's N-pole (S-pole) on the inner magnet's S-pole (N-pole) has a pulling effect, and at the same time, the outer magnet's N-pole (S-pole) has a pushing effect on the inner magnet's previous N-pole (S-pole), which has a pushing effect on the inner magnet's N-pole (S-pole). At the same time, the N-pole (S-pole) of the outer magnet has a pulling effect on the previous N-pole (S-pole) of the inner magnet, so that the inner magnet has a tendency to rotate with it, which is the working principle of the push-pull magnetic circuit of the magnetic coupling. When the outer magnet of the N pole (S pole) just located in the inner magnet of the two poles (S pole and N pole) between the resulting push and pull to reach the maximum, thus driving the inner magnet rotation. In the transmission process, the isolation cover separates the outer and inner magnets, and the magnetic lines of force pass through the isolation cover to transmit the power and motion of the outer magnet to the inner magnet, thus realizing a contactless sealed transmission.

Features

● High-efficiency power transmission: the permanent magnetic coupling adopts advanced magnetic coupling technology, which can ensure the efficient power transmission and reduce energy loss at the same time.
● No need for physical connection: the two rotating parts are connected magnetically without the use of traditional mechanical couplings, thus avoiding mechanical wear and corrosion problems.
● Long service life and low maintenance: Due to the lack of physical contact, permanent magnetic couplings experience minimal wear and tear, resulting in a longer service life and lower maintenance costs.
