BM4 series motors have the following structural features:
1. The embedded column stator and rotor design has higher oil distribution accuracy and mechanical efficiency.
2. Double rolling bearings at both ends are designed to have large lateral bearing capacity.
3. Reliable shaft seal design can withstand higher back pressure and can be used in series and parallel.
4. The forward and reverse conversion is convenient and the rotation speed is stable.
5. Various installation forms of connecting flanges, output shafts and oil ports.
6. It is widely used in petroleum, coal machinery, small cranes and other construction machinery.
