Specifications:
The document outlines the specifications for various gear combinations and DC motors. It includes worm gear GS 3, spur gear Z 6 Z 8 M 7, and planetary gear PM 50. Rotary encoders and brakes are available upon request. Dimensions for types PC 6325 and PC 6355 are 93.5 mm and 123.5 mm, respectively.

DC Motor Features:
The DC motor comes with an integrated CANopen interface, featuring an integrated speed controller. It can be controlled via analog nominal value or CAN bus (CANopen, Drive Profile DSP-402). The motor uses mechanical commutation with a 12-part commutator and a 2-pole permanent ferrite magnet. It has a service life of 3,000 hours under S1 duty and an insulation material class of B, with an optional upgrade to F. The system protection is IP 40, with an optional upgrade to IP 54. Special models are available for short-time operation with high performance.

Performance Parameters:
The nominal power is 44 W and 85 W, with a nominal speed of 3000 rpm for both. Nominal torque is 14 Ncm and 27 Ncm, with starting torque at 30 Ncm and 60 Ncm. Nominal current is 2.6 A and 4.7 A. The nominal efficiency is 67% and 71%.

Mechanical and Thermal Characteristics:
The motor weighs 1.1 kg and 1.6 kg, with a moment of inertia of 563 gcm² and 1020 gcm². The mechanical time constant is 27 ms and 20 ms. The admissible ambient temperature ranges from -20°C to +40°C, with a maximum rotor temperature of +120°C. The shaft diameter is 8 mm, with a maximum axial force of 20 N and a maximum radial force of 220 N.

Gear Combinations:
The document provides detailed tables for planetary gear PM/P 50, spur gear Z 6, and worm gear GS 3, with various stages and corresponding rpm and Nm values. All torques are calculated with a duty factor of 1, and additional reduction ratios are available upon request.

Additional Information:
The document mentions that motor power must be limited if necessary to prevent overload at the gear output. The nominal voltage for types PC 6325 and PC 6355 is 24 Volt DC.
