BMM Series orbital hydraulic motor

HBOETH BOLE HYDRAULIC BMM20 orbital hydraulic motor

The BMM/OMM series represents a micro-type shaft-port distribution hydraulic motor designed for space-constrained installations. Featuring a monolithic rotary stator assembly with 4/5-tooth configuration, this motor combines ultra-compact dimensions, lightweight construction, and industry-leading power density.

Key Advantages:

Monolithic rotary stator manufactured through globally patented precision machining processes, optimizing compactness, energy conversion efficiency (>92%), maximum rotational speeds (up to 3000 RPM), and 20,000-hour service life.
Multi-stage pressure-rated shaft seals (up to 250 bar) enabling flexible series/parallel circuit arrangements.
Innovative power-to-weight ratio architecture achieving power densities exceeding 0.5 kW/kg.
Dual-circuit compatibility design supporting bidirectional operation in closed-loop systems.
