BD/EPRM Hydraulic motor
The BD/EPRM hydraulic motor from LöSi® combines the proven Geroller Gerotor technology of the EPRM series with an integrated multi-disc brake to provide drive and holding functions in a compact unit. With displacement ranges from approx. 80 cm³/rev to 397 cm³/rev and static holding torques in the range of hundreds of Newton metres, this motor offers a reliable solution for applications with high torque requirements AND as a holding or parking brake. Choose the BD/EPRM hydraulic motor – if you want drive power and safety in one module.
What is a BD/EPRM Hydraulic Motor?
The BD/EPRM hydraulic motor is a further development of classic orbital motors. It combines the proven Geroler technology of the EPRM series with a firmly integrated, hydraulically released multi-disc brake in a single housing.
This construction is the answer to space constraints in modern machines. Instead of mounting and piping motor and brake separately, you receive a compact unit that seamlessly combines drive and holding function (safety).
Advantages of the BD/EPRM Series
The main advantage of the BD/EPRM lies in the reduction of complexity. Fewer components mean less installation effort and fewer potential leakage points. Technically, the series impresses with:
- Geroler Technology: By using rollers in the planetary gear set, sliding friction is minimized. This improves start-up behavior and increases service life compared to simple motors.
- Integrated Brake: The hydraulically released multi-disc brake ensures safety at standstill (holding function).
- Simple Integration: Reduced piping effort, as the brake is part of the motor unit.
Typical Areas of Application for the BD/EPRM Hydraulic Motor
The BD/EPRM demonstrates its strengths wherever loads must be held securely and installation space is limited:
- Lifting Technology & Winches: Reliable holding of the load at motor standstill.
- Conveyor Technology: As a backstop on inclined conveyor belts.
- Mobile Machinery: Wheel drives in construction machinery that require a parking brake.
- Plastics Machinery: Precise positioning of tools.
Variants, Selection & Technical Data
The BD/EPRM series offers flexibility for diverse applications. The displacements range from approx. 80 cm³/rev to 397 cm³/rev.
A concrete performance example is the model BD/EPRM 400 C D (397 cm³/rev).
Pay particular attention to the brake parameters during design:
- Static Holding Torque: Offers e.g., 400 Nm safety reserve (depending on model).
- Opening Pressure: The brake releases from approx. 21 bar. Your system must ensure this pressure in the supply line.
- Connections: Check the position of the leakage oil and brake release ports for clean routing.
