KD 6

Product catalog summary

Specifications:
The document provides detailed specifications for various motor types, including KD 642, KD 662, KD 644, and KD 664. It outlines dimensions, recommended gear combinations, and properties such as connection requirements, service life, insulation class, and system protection levels. The motors are reversible asynchronous types with options for thermal protection and custom designs.

Procedures:
The document specifies connection procedures for the motors, which can be connected to a 230 V / 50 Hz system with a running capacitor or a 400 V / 50 Hz three-phase system using K4 terminal boxes.

Norms and Standards:
The motors have a service life of 20,000 hours under S1 duty and are protected under IP 44, with optional upgrades to IP 65. Insulation material class is B, with an option for class F.

Recommendations:
Recommended gear combinations include worm gears (S 567, S 668), spur gears (Z 8, Z 6, M 7), and planetary gears (PM 50). The document also suggests additional reductions and combinations upon request.

Performance Parameters:
Nominal power ranges from 11 W to 42 W, with nominal speeds of 1250 rpm and 2650 rpm. Nominal torque varies from 7.0 Ncm to 15.4 Ncm, and starting torque ranges from 3.5 Ncm to 27.0 Ncm. Nominal efficiency is between 27.5% and 60.5%.

Limitations:
Maximum ambient temperature is -20 to +40°C, and maximum stator temperature is +120°C. Maximum axial and radial forces are 20 N and 220 N, respectively.

Additional Information:
The document includes tables with detailed gear unit combinations and performance metrics for different gear ratios. It also notes that all torques are calculated with a duty factor of 1, and motor power may need to be limited for maximum load at the gear output.
