The main element of the basic type permanent magnet coupler is a conductor rotor and a surrounding permanent magnet rotor. The conductor rotor is a steel rotor with a copper ring, which is connected to the motor shaft. The permanent magnet rotor is an aluminum rotor with permanent magnet materials. Connected to the shaft of the working machine, the permanent magnet rotor and the conductor rotor form a fixed gap and never contact. When the motor rotates, the relative movement between the rotors can induce eddy currents in the conductors, and the magnetic fields generated by the eddy currents interact with the permanent magnet magnetic fields to realize torque transmission.

NF high speed non-contact-type backstop adopts wedges for backstop internally, which has a large bearing capacity. The product is installed at the high-speed end of the system. When the backstop reaches a certain speed, the wedge is separated from the inner and outer ring surfaces under the action of centrifugal force to realize non-contact operation. This series of backstops includes 11 specifications, and the backstop torque covers 1～25KN.m.

The constant permanent magnet coupler is composed of two symmetrical disc structures, which can change the output torque by adjusting the air gap between the conductor rotor and the permanent magnet rotor in a small range, so as to realize the torque transmission between the motor and the load. The driving end and the driven end are each composed of two hubs with clearance fit for easy installation. They are connected to the motor shaft and the load shaft by a locking disc, and do not require any keyway or pin for fixing. When the load exceeds a certain torque limit value, the magnetic induction force will produce an axial repulsive force to enlarge the air gap, so that the load is completely separated from the motor, and the motor is protected from damage.

Bibby coupling is a kind of "metal flexible coupling". Its special structure design combines the high torque of gear coupling and the flexibility of elastic coupling. It is one of the most advanced transmission coupling parts in the field of mechanical transmission. . Based on the original advantages and performance, the T05 series quick disassembly and assembly Bibby coupling independently developed by Jingji Company and verified by the market for many years completely solves the problem of difficulty in disassembly and assembly of traditional couplings, and is more economical and reliable.

The brake system of the disc brake device is an important function indispensable for most mechanical equipment. In large-scale low-speed driving equipment such as belt conveyors and mine hoists, disc brake devices are required. Whether you are in an explosion-proof mining environment or a dangerous dust environment, whether you are stopping at a reduced speed or being controllable, the precision-based disc brake device meets your needs. The disc brake device is mainly composed of the brake body, hydraulic station, and electric control device.

The programmable control box is controlled by Siemens or AB’s original PLC, equipped with a high-definition touch screen, which can control the start/stop of permanent magnet motors, frequency converters, water-cooled motors and cooling fans (water-cooled motors need to be equipped with electromagnetic starters). Collect the temperature signals of the permanent magnet motor and the cooling device, and interlock with the motor start circuit to ensure the safe and reliable operation of the belt conveyor. The control box reserves Ethernet and RS485 communication interfaces, which can transmit data with the frequency converter, integrated protection system, belt conveyor main control system, and integrated automation system.
