KD 8

Product catalog summary

Specifications:
The document provides detailed specifications for KD 842 and KD 862 motor types, including dimensions, recommended gear combinations, and motor properties. The motors are reversible asynchronous types with connections available for 230 V / 50 Hz or 400 V / 50 Hz systems. They require a running capacitor and have a service life of 20,000 hours under S1 duty. Insulation material class is B, with an optional upgrade to F, and the system protection is IP 44, optionally up to IP 65.

Performance Parameters:
Nominal power ranges from 43 W to 65 W, with nominal speeds at 2650 rpm and nominal torque between 15.5 Ncm and 23.5 Ncm. Starting torque varies from 11.5 Ncm to 66.5 Ncm. The motors have a nominal efficiency ranging from 57% to 65.5%.

Gear Combinations:
Recommended gear combinations include worm gear S 668, spur gear Z 8, and planetary gear PM 60. The document provides detailed tables of gear ratios (i) and corresponding output speeds (rpm) and torques (Nm) for each gear type.

Additional Features:
Options for thermal protection, special shafts, and custom designs are available. The motors can be designed for short-time duty with high performance. The document also lists additional recommended gear combinations and reductions upon request.

Environmental and Mechanical Limits:
The motors operate within an ambient temperature range of -20°C to +40°C, with a maximum stator temperature of +120°C. They have a shaft diameter of 8 mm, with maximum axial and radial forces of 20 N and 220 N, respectively.

System Technology:
The document includes tables for system technology, detailing nominal voltages and gear unit combinations for different motor types. All torques are calculated with a duty factor of 1, and additional reductions are available upon request.
