CV Series Vertical Gear Motor – Flange-Mounted Models, Shaft Sizes,
Ratios & Power Guide
The CV series is a vertical (flange-mounted) helical geared motor designed for applications where floor
space is limited or where the driven equipment requires a vertical shaft orientation. This guide covers all
standard models, shaft diameters, ratios, and power ratings.
