The M hydraulic motors are bent axis design motors. They are characterized by high power and significant rotationalspeeds. The bent axis design hydraulic motors guarantee high global efficiency and high operating pressure. They are designed for use in continuous work in heavy duty applications. These motors are used for direct drive or through gearing, depending on the application.
Rotational speed range: from 200 through 8000 rpm; maximum continuous pressure: up to 400 bar.
All motors of M series are based on bent axis design, which ensure wide range of rotational speed and reduced size envelope. They combine high performance and extremelyhigh global efficiency. High pressure oil injection on piston heads reduces friction, heat and wear. All structural components are made from similar materials resulting in consistent thermal expansion and exeptional reliability. The M hydraulic motors have ATEX certificate and they are classifiedin group IIcategory 2DT4 (standard). On requestthe motors can be supplied withdifferentlevels ofcertification-eg. group IIcategory 2G.
The M63 hydraulic motors are available with four types of shafts: two splined W1 and W2 and two keyed D1 and D2. There are seven options of oil ports: L0, M0, N0, N1, P0, Q0, Q1; flushing valve VBS 091180 is available for N1 and Q1 (M32-108 motors).
Features:
- Displacement: 12 – 126 cm3/rev;
- Rotational speed range: 200 – 8000 rpm;
- Maximum pressure: 400/450 bar (continuous/peak);
- Maximum power: 63 – 284 kW.
Advantages:
- Reinforced seals;
- Piston heads engaged into barrel assure of no risk of piston – plate separation;
- Motor barrel and valve plate are automatically alligned what guarantees long service life because of no radial mechanical stress;
- Excellent rotating smoothness;
- Constant torque;
- Low noise level.
Applications
The M motors are used in excavators, bulldozers, crushers, conveyors, large fans, injection molding machines etc. These motors are also used in mining, e.g. drills and winchers, and in shipbuilding, e.g. winchers, cranes, drives etc.
