SPM+ / TPM+ endurance

  • SPM+ endurance: Water-cooled servo actuators for maximum efficiency, high power density and minimum cycle times

Stronger – shorter – cooler

Actuators with water cooling for maximum efficiency, high power density and minimum cycle times. Thanks to a flexible modular system, various gearheads can be integrated in a manner tailored to the motors. The highly compact design opens up numerous possibilities in terms of construction: smaller machinery thanks to maximum power density.

  • Technical data
  • Options

Highly compact motor/transmission unit with water cooling thanks to innovative stainless steel cooling technology consisting of a precision planetary gearhead and permanent-magnet-excited synchronous servo motor with resolver

Two versions:

  • SPM+ endurance, servo actuator with one or two-stage gearhead and output shaft
  • TPM+ endurance, servo actuator with one, two or three-stage gearhead and output flange

Increased energy efficiency
Low torsional backlash plus high rigidity provide for smaller motors and reduced energy consumption and investments.

Increased productivity
An actuator with a low moment of inertia and an extremely rigid drive train provide for maximum precision and power.

Increased availability
Especially when used in open cooling circuits, the stainless steel cooling system provides for a durable and low-maintenance drive solution.

SPM+ endurance:

  • Five sizes
  • Max. output speed of 1655 to 1125 RPMs
  • Max. output torque of 260 to 4,500 Nm
  • Max. Motor capacity of 5.9 to 152 kW

TPM+ endurance:

  • Five sizes
  • Max. output speed 35 to 1500 RPMs
  • Max. output torque 275 to 10,000 Nm
  • Max. motor capacity of 5.9 to 152 kW

You can choose from:
