Product catalog summary

Specifications:
The document provides detailed specifications for three-phase asynchronous motors, including dimensions, nominal power, speed, torque, and efficiency. The motors are designed for a 400 V / 50 Hz three-phase system, with optional designs for other voltages and frequencies. They feature a standard connection using K22 type plug-in connectors and have a service life of 20,000 hours under S1 duty. The insulation material class is B, with an optional upgrade to F, and the system protection is IP 44, with an option to increase to IP 65.

Procedures:
The document outlines the procedures for selecting gear combinations, including worm, spur, and planetary gears. It provides detailed tables with gear ratios, speeds, and torques for different motor types (D 842, D 862, D 882, D 844, D 864, D 884).

Norms and Standards:
The motors comply with standard connection and protection norms, with options for customization to meet specific requirements, such as thermal protection, special shafts, and stainless steel construction.

Recommendations:
Recommended gear combinations are provided for optimal performance. The document advises on additional reductions and combinations upon request, emphasizing that all torques are calculated with a duty factor of 1. It also notes that motor power must be limited if necessary to prevent overloading the gear output.

Key Data from Tables:
The tables provide critical data on gear ratios, speeds (rpm), and torques (Nm) for various gear types and motor models. For example, worm gear ratios range from i=2.5 to i=100, with corresponding speed and torque values. Spur and planetary gear data are similarly detailed, allowing for precise selection based on application needs.
