TPMA HIGH TORQUE Rotary Servo Actuators Compact AC servo gearhead systems The most compact, most dynamic servo actuators in the world! Provide high dynamic performance in an extremely compact package. Ideal for high cyclic applications in compact machine designs. TPMA overview Precision WITTENSTEIN alpha gearhead, servomotor and feedback integrated into one compact package 62% shorter overall length and much lower weight than conventional servomotor-gearhead designs higher acceleration rates for quicker cycle times high stiffness and low inertia eliminate need for flanges and couplings - utilizes large dual tapered roller bearings, eliminating the need for additional support bearings in the customer's application high positioning accuracy with < 3 arc-minutes of backlash standard; reduced backlash version < 1 arc-minute low torque ripple for extremely smooth operation allow for direct mounting of turntables and loads ideal for indexing applications, i.e., turntables, tool changers and robots Can be operated with most brushless servo controllers on the market low noise level maintenance free Specifications TPMA - Available in 3 models, providing 480-2600     Nm acceleration torque 2.5 times more torque/volume than conventional     solutions TPMA - 3-stage: ratios 110/220 backlash standard -- < 3 arcmin; reduced < 1     arcmin efficiency > 93% resolver or single- or multi-turn absolute encoder Options mechanical holding brake single- or multi-turn absolute encoder - eliminates     the need for homing on start-up pre-assembled pinion, plus complete rack &     pinion solution available View 31 page TPMA brochure
