BMM Compact Orbit Hydraulic Motor
The smallest envelope in the THOTH orbital family — fits where no other hydraulic motor can, with the highest speed capability in the BM range.
BMM is the entry point of the THOTH orbital motor range — a gerotor cycloid motor with a ductile cast iron shell, designed for lighter loads and intermittent operation. The TMM variant uses a geroler gear set for smoother running.
Its defining strength is size: the smallest footprint in the family, with speed capability up to 1,950 r/min — ideal for compact drive modules where a gearbox would add cost and envelope.
Widely applied in agriculture, forestry, plastics machinery, machine tools, and light material handling.
