Specifications:
The document outlines various gear and motor combinations, including worm gears (S 668, S 769, SC 401), spur gears (Z 8, M 7, M 10), planetary gears (PM 60, PM 80), rotary encoders (RV 20, RV 30, RI 20/RI 30), brakes (B 77), and electronics (UCE 24). It also details the dimensions and characteristics of the DC motor with a permanent magnet, including connection options, commutation, magnetic system, service life, insulation material class, system protection, and special model options.

Motor Characteristics:
The DC motor features a nominal power of 72.0 to 95 W, nominal speed of 3000 rpm, nominal torque of 23 to 30.2 Ncm, and a nominal current of 3.9 to 5 A. It has a starting torque of 130 to 160 Ncm, idling speed of 3600 to 3700 rpm, and no-load current of 0.4 A. The motor's efficiency ranges from 72.0% to 74.5%, with a terminal resistance of 0.7 Ohm and rated input power of 113 to 127 W.

Dynamics and Environmental Conditions:
The motor weighs between 2.1 to 2.2 kg, with a moment of inertia of 1325 to 1725 gcm² and a mechanical time constant of 24 to 29 ms. It operates within an ambient temperature range of -20 to +40°C, with a maximum rotor temperature of +120°C. The shaft diameter is 8 mm, with maximum axial and radial forces of 20 N and 220 N, respectively.

Gear Combinations:
The document provides detailed tables for planetary, spur, and worm gear combinations, specifying the reduction ratios, resulting speeds, and torques for each configuration. It emphasizes that all torques are calculated with a duty factor of 1 and notes that additional reduction ratios and recommended combinations are available upon request.

Additional Notes:
The document mentions that motor power must be limited if necessary to prevent exceeding the maximum load at the gear output. It also highlights the availability of special shafts and custom designs upon request.
