The permanent magnet synchronous variable frequency integrated machine electric drum system is a new type of driving equipment independently developed and produced by our company, with a low-speed high torque external rotor permanent magnet synchronous motor as the core. The motor rotor is the driving system drum, eliminating intermediate transmission equipment such as reducers and couplings, truly achieving direct drive transmission, higher efficiency, simpler and more compact structure, and smooth operation with low maintenance costs. Can be applied in fields such as belt conveyors, cranes, food processing oil presses, etc.

1) Cancel mechanisms such as reducers and couplings, and directly connect the motor rotor to the load, resulting in a shorter transmission chain and higher transmission efficiency;

2) The frequency converter is integrated with the drum to reduce the occupancy rate of chamber equipment;

3) Good energy-saving effect;

4) The motor adopts permanent magnet excitation, which does not require reactive excitation current and has a high power factor;

5) Efficient work with a wide range, and can approach rated efficiency even under light loads;

6) Compact structure, small volume, and light weight;

7) The system has low vibration, low noise, and high operational stability; Low operation and maintenance costs, basically achieving maintenance free operation.
