Document Overview

This technical document from Dipl.-Ing. Wilhelm Winkelmann GmbH & Co. KG provides a detailed comparison of electric motor construction types according to standards EN 60034-7: 2001 (Code I and Code II) and the older DIN 42950. It includes designations, mounting types, and terminal box positions for various motor configurations.

Main Sections

1. Type of Construction Comparison

The document compares motor construction types across three standards: EN 60034-7 Code I, Code II, and DIN 42950. It lists corresponding designations and descriptions for each motor mounting style.

Key Mounting Types and Corresponding Codes

• IM B3 / IM 1001 / B3: Foot-mounted motor with horizontal shaft.
• IM V5 / IM 1011 / V5: Foot-mounted motor with vertical shaft.
• IM B5 / IM 3001 / B5: Motor without feet, equipped with a FF flange.
• IM V1 / IM 3011 / V1: Motor without feet, with FF flange (vertical shaft).
• IM B35 / IM 2001 / B3/B5: Foot-mounted motor with FF flange.
• IM V15 / IM 2011 / V1/V5: Foot-mounted motor with FF flange (vertical shaft).
• IM B14 / IM 3601 / B14: Motor without feet, with FT flange.
• IM V6 / IM 1031 / V6: Foot-mounted motor (vertical shaft).
• IM B34 / IM 2101 / B3/B14: Foot-mounted motor with FT flange.
• IM V3 / IM 3031 / V3: Motor with FF flange (vertical shaft).
• IM B6 / IM 1051 / B6: Foot-mounted (left) and wall-mounted motor.
• IM V35 / IM 2031 / V3/V6: Foot-mounted motor with FF flange (vertical shaft).
• IM B7 / IM 1061 / B7: Foot-mounted (right) and wall-mounted motor.
• IM V18 / IM 3611 / V18: Motor without feet, with FT flange (vertical shaft).
• IM B8 / IM 1071 / B8: Foot-mounted motor with ceiling mounting.
• IM V17 / IM 2111 / V5/V18: Foot-mounted motor with FT flange (vertical shaft).
• IM V19 / IM 3631 / V19: Motor without feet, with FT flange (vertical shaft).
• IM V37 / IM 2131 / V6/V19: Foot-mounted motor with FT flange (vertical shaft).

2. Terminal Box Position Codes

The document defines terminal box positions relative to the drive end of the motor, using clock-face notation:

• R (Right): 3 o'clock position
• B (Bottom): 6 o'clock position
• L (Left): 9 o'clock position
• T (Top): 12 o'clock position
• Without specification: Terminal box position not specified

Critical Information and Recommendations

• The document serves as a reference for selecting motor mounting types according to international and older German standards, facilitating compatibility and standardization.
• Understanding the terminal box position codes is essential for installation and maintenance planning.
• The comparison aids in identifying equivalent motor designs across different standards, which is critical for replacement, repair, or specification purposes.

Summary

This document is a technical reference for electric motor construction types, providing a clear mapping between EN 60034-7 Codes I and II and DIN 42950 standards. It details mounting configurations, flange types, shaft orientations, and terminal box positions, supporting engineers and technicians in motor selection, installation, and standard compliance.
