Permanent magnet hysteresis cable drum is similar to constant tension cable drum, which is only second to PLC variable frequency cable reeling drum in automatic regulation. It is the best solution for conventional working conditions. Through the magnetic coupling effect, the cable is always in tension during the process of reeling and unreeling, so that the cable drum and the cart can run synchronously and reliably. This scheme can greatly reduce the purchasing cost of users.    

Performance characteristics:

● According to the actual working conditions, the output torque can be adjusted and has good self-control function;

● The cable drum slip ring box is equipped with a new technology patented product, hygrothermostat (a constant temperature and humidity device), which eliminates the phenomenon of slip ring box explosion;

● Compact structure, reliable operation and convenient installation and maintenance.
