The scraper USES a low-speed semi-direct drive permanentmagnet drive system, which is composed of permanent magnet fre-quency conversion control system, permanent magnet synchronous

motor and reduction device.Permanent magnet synchronous motor anoreducer are integrated; The power is directly transmitted through spline between the permanent magnet drive system andthe sprocket shaft set. The product has the following characteristics:
1. Shortened length of transmission is convenient for the hydraulic support of the transition section to efectively sup
port the head and tail of the scraper conveyor.
2.in the thin coal seam workirg face, it is more favorable for the shearer to advance alona the aoueduct toward thenose and tai direction and reduce theirarion oirrancuer coa
3.Shorened transmissiorstem operation,lower noise and improved reliability/ reduce the impact on the chain and equipment.

4.freauency conversion start

5. Good controllability, which cansolve the mut.power balance problem of the scraper.

6. Reduce the number of components, facilitate installation and reduce daily maintenance
