(1) requires high-precision alignment, and poor alignment will seriously shorten the service life;
(2) No overload protection;
(3) The mechanical impact on the equipment is inevitable when the motor starts and the load changes;
(4) Long installation and maintenance time;
(5) High maintenance cost;
(6) The service life is short, and it needs to be replaced after 1-2 years;
(7) No damping effect and energy saving effect.
Compared with couplings, permanent magnet couplings have the following characteristics:
(1) Long service life and design life of 30 years;
(2) large dislocation tolerance, convenient installation and time saving;
(3) It has the function of buffering soft start, which avoids the mechanical impact when starting and prolongs the service life of the equipment;
(4) No mechanical connection, good vibration reduction effect;
(5) The energy-saving effect is obvious, and the energy-saving rate reaches10%-50%;
(6) It has overload protection function, which improves the reliability of the whole motor drive system.
According to the announcement of Yaozhong Group, which obtained this patented technology, the McFOSS permanent magnet coupling is very reliable in safety performance, which has many advantages over the coupling and the effect is more remarkable.
