6 FAQs about [Solar power generation permanent magnet coupling]

Why are permanent magnet couplings used in extreme environmental conditions?

1. Introduction Permanent magnet couplings (PMC) are used extensively in extreme environmental conditions because of their capability of transmitting torque from a primary device to a secondary follower without any physical contact. This noncontact property produces less mechanical friction with auto-alignment and over-torque protection ability.

What types of magnetic couplings are used?

The types of the magnetic couplings used for this study are a radial flux-CPMC (RF-CPMC) with magnet retaining rings and a flux concentrating-CPMC (FC-CPMC) with inner and outer rotor yoke changed by retaining rings. The main criterion of the whole analysis was to find a model that is capable of ensuring a torque above 1kNm.

Can high torque coaxial permanent magnet couplings be used in tidal current generation?

The electromagnetic and electromechanical characteristics are used for comparison. Based on the installation environment and the magnet use, RF-CPMC is prototyped and tested. This paper presents design and comparative study of high torque coaxial permanent magnet couplings (CPMC) for the use in a tidal current generation (TCG) system.
