The Versatile MHA Series Motor

  • High torques at low speeds:
    Direct coupled drives to 20 Nm/Bar
    (1,000 lb ft/1,000 psi).
    Speed reducer drives to 2000 Nm/Bar
    (100,000 lb ft/1,000 psi).
  • Simple but rugged design makes for an efficient and reliable power source.
  • Very few working parts mean reduced long term maintenance costs.
  • High power-to-weight ratio.
  • Can be run in extreme environmental conditions e.g. Low/high ambient temperatures. Hazardous explosive atmospheres.Totally immersed. (Consult PSS).
  • Subject to certain performance derating, may be operated with all fire resistant fluids such as High Water Based Fluid and Phosphate Ester.
    (Special seals are required for Phosphate Ester).
  • Low rotational inertia allows fast response of speed changes.
  • Rapid response to reversals.
  • Smooth rotation down to 1 r.p.m. depending on nature of drive.
  • Operate at full stall torque without damage.
  • Extra large taper roller bearings that enable substantial radial and axial shaft loading.
  • True mechanical free-wheel.
  • Optional integral spring applied pressure released safety brake.
  • Optional flange mounted valves for load control, pressure relief and servo speed and directional control.
  • Interchangeability with other well-known makes of radial piston motor.
  • Design and manufacture of bespoke motors to customer requirements.
