Abstract

A control mode is made into an easy adjustment corresponding to the load state or drive state of an inner side rotating body, and a better control mode is realized through an easy and compact structure. A magnetic coupling controlling means (10) comprises an outer side function body (10MT) of a rotor part (12) capable of rotating in an inner periphery, an inner side rotating body (14) which is disposed with intervals at the periphery side of the rotor part, tubings (P) of tube wall which are disposed between an external function body and an inner side rotating body, a magnetic coupling structure which is provided with a plurality of external side magnetic poles (12c) arranged around an axis in an inner periphery of the rotor part, and a plurality of internal side magnetic poles (14b) which match with the plurality of external side magnetic poles at the external periphery of the inner side rotating body and are arranged through magnetic coupling in a rotating direction, phase difference detection units (15, 16, 120) which detect the phase difference between the external side magnetic pole and the internal side magnetic pole, and external side function body control units (103, 106, 107) which control the external side function body based on the phase difference.

Description

technical field [0001] The present invention relates to a magnetic coupling control device, in particular to a device structure and control technology suitable for non-contact control of an inner rotating body arranged inside a pipe. Background technique [0002] Drive systems are known which use magnetic coupling for the transmission of rotational movements in a contactless manner. In this drive system using magnetic coupling, for example, it is known that a pair of magnetic disks having a plurality of magnetic poles arranged in a rotational direction are arranged at opposite positions, and in a manner synchronized with the rotation of one magnetic disk, it is possible to The structure that drives the other disk in rotation. [0003] On the other hand, in order to drive objects arranged in various pipes, there is also known a mechanism that uses magnetic force to drive the objects from the outside of the pipes. As piping, for example, besides a water pipe, a sewer pipe, e...
