CPMH Series Hydraulic Motors – Frequently Asked Questions

What are the core features of the CPMH hydraulic motors?

The CPMH hydraulic motors feature a spool valve with Geroler technology, offer low starting torque, and deliver high efficiency. They are designed for flange mounting, include an internal check valve, and are available in various special configurations.

Which models of the CPMH hydraulic motors are available, and what are their main differences?

Five main models are available: CPMH 200, CPMH 250, CPMH 315, CPMH 400, and CPMH 500. The primary distinguishing factor is the displacement, ranging from 203.2 cm³/rev (CPMH 200) to 489.2 cm³/rev (CPMH 500). This directly affects the maximum possible speed, torque, power output, and permissible pressure drop.

What operating modes are defined for the CPMH motors, and what do they mean?

  • Continuous (Cont.): Normal, uninterrupted operation.
  • Intermittent (Int.): Up to max. 6 s per minute; higher performance values than in continuous operation.
  • Peak: Very short-term operation up to max. 0.6 s per minute; highest permissible performance values.

What output shaft options are available for the CPMH motors, and how do they differ?

  • C: Ø 32 mm cylindrical with keyway – max. 77 daNm
  • CB: Ø 35 mm cylindrical with keyway – max. 95 daNm
  • Co: Ø 31.75 mm (1¼") cylindrical with keyway – max. 77 daNm
  • SH: Splined shaft (SAE 6B) – max. 40 daNm
  • SB: Ø 31.75 mm splined, 14 teeth, DP 12/24 – max. 95 daNm
  • S: Ø 31.75 mm (1¼") splined, 14 teeth, DP 12/24 – max. 95 daNm
  • K: Tapered 1:10 with keyway – max. 95 daNm

How is the standard rotation direction of a CPMH motor determined?

By default, the motor rotates clockwise when port “A” is pressurized. When port “B” is pressurized, the motor rotates counterclockwise. A reversed standard rotation direction can be ordered upon request.

What is the meaning of the case drain and case drain pressure, and what are the benefits of a case drain line?

The case drain is the internal space of the motor where leakage oil collects; the case drain pressure is the pressure present there. Routing this oil away (case drain line) offers several benefits: flushing of the system, cooling of the motor, and extended seal life.

What calculations are important when applying CPMH motors in vehicle drives?

  • Motor speed (n): Derived from vehicle speed, rolling radius, and gear ratio.
  • Rolling resistance (rr): Depends on total weight and rolling resistance coefficient.
  • Gradient resistance (Gr): Force required to overcome slopes (weight, angle, friction).
  • Inertia force (Fa): Force required to accelerate to target speed within the given time.
  • Drawbar pull (dP): Additional force for trailer operation.
  • Total tractive effort (TE): Sum of all forces plus approx. 10 % for air resistance.
  • Motor torque (M): Required torque per motor based on TE, rolling radius, number of motors, gear ratio, and gearbox efficiency.
  • Wheel adhesion (MW): Maximum transferable friction force to avoid slip (MW > M).
  • Radial motor load (Prad): Total load on the motor shaft with directly mounted wheels.
