BMR orbital hydraulic motors from the Rolltorq brand are crafted for low-speed operations under low to medium loads. The BMR series boasts maximum speeds ranging from 160 to 775 rpm and power outputs of up to 10 kW.
Specifications
- 5 to 775 rpm of rotational speed range
- Up to 140 bar of continuous pressure
The BMR orbital motors are medium-sized units fitted with a gerotor set that includes rollers. This setup offers high starting torque, low starting pressure, and the ability to handle high allowable pressures, albeit at a lower maximum rotational speed. The cardan shaft spins the distributor valve and transfers mechanical energy from the gerotor set to the output shaft. The valve is equipped with hydrodynamic bearings, guaranteeing virtually infinite life as long as load ratings aren't surpassed. Additionally, these motors boast shaft bearings that greatly enhance their longevity.
BMR motors are generally interchangeable with motors from series such as OMR, MR, OMZR, and SMR. However, durability, efficiency, and parameter stability can vary between different manufacturers' series.
