CMP Series Hydraulic Motors - Frequently Asked Questions
What are the main features and specifications of CMP hydraulic motors?
CMP hydraulic motors are spool valve Gerotor motors for medium to light-duty applications with the following features:
- Displacement: 49.5 cm³/rev to 396 cm³/rev
- Max. speed: up to 1100 rpm (CMP 100)
- Min. speed: down to 5 rpm (depending on model)
- Max. torque: 12.6 daNm (continuous) up to 52.0 daNm (peak load)
- Max. output power: 40.0 kW
- Temperature range: -40 to 140 °C
- Optimal viscosity: 20–75 mm²/s
- Recommended filtration: ISO 20/16 (min. 25 µm)
In which typical applications are CMP hydraulic motors used?
CMP hydraulic motors are versatile and are used in, among others:
- Conveyor systems
- Feed mechanisms for robots and manipulators
- Metalworking machines
- Textile machinery
- Agricultural machinery
- Food processing industry
- Lawn mowers
What types of shaft options are available for CMP motors and what are their torque limits?
- C-shaft (Ø25 mm straight): Key A8x7x32 DIN 6885 – max. 34 daNm
- CO-shaft (Ø1" straight): Key ¼"x¼"x1¼" BS46 – max. 34 daNm
- SH-shaft (splined, SAE 6B): BS 2059 – max. 40 daNm
These variants allow adaptation to different mechanical requirements.
What fluid requirements and recommendations apply for operation?
- Mineral oil-based Type HM (ISO 6743/4) or HLP (DIN 51524)
- Optimal viscosity: 20–75 mm²/s
- Minimum viscosity: 13 mm²/s at 50 °C
- Max. operating temperature: 82 °C
- Filtration: ISO 20/16 (min. 25 µm)
- For synthetic fluids: consult manufacturer for alternative seal options
What is meant by "Continuous operation", "Intermittent operation" and "Peak load"?
- Continuous: Operation without interruption
- Intermittent: Max. 10% per minute, speed and pressure drop not simultaneous
- Peak load: Max. 1% per minute, short-term maximum values
These specifications are important for correct sizing and long service life of the motor.
What are the typical connection types and dimensions?
- Flange mounting with side ports
- Main ports: G 1/2 (depth 16 mm)
- Case drain port: G 1/4 (depth 12 mm)
- Pilot diameter: Ø82.5 mm
- Length Lmax: 135.5 mm (CMP 50) to 182.0 mm (CMP 400)
How is the permissible radial shaft load calculated?
The permissible radial load depends on speed (n, RPM) and distance L. Formula:
Prad = 800 / (n / 15000 + (L / 95)) × x (x from diagram values)
Limits:
- Max. 150 daN (continuous)
- Max. 200 daN (intermittent)
The limits from the diagrams must not be exceeded to avoid shaft and seal damage.
