INTRODUCTION

2.1

General

A6 VEC is one of the main components in the A6 system. A range of motor speeds
and gearbox ratios makes it possible to regulate the speed range.
A6 VEC is available with or without free--wheeling gears.
A6 VEC motor with gearbox is a permanent magnet DC motor with combined
toothed gears and worm gears. It can be configured for 42 or 75 V DC operation
and is designed for use with the ESAB regulators PEG1 (42 V DC), PEH (42 V DC),
PEF (75 V DC) and PTF (75 V DC).
