There are many servo driven applications that don’t require the highest precision gearhead. There are even more that can benefit from a right angle configuration for saving space and providing mounting versatility. Unfortunately there are few economical solutions for smaller servo motors. That is until now.
The Varvel servo worm is ideal for multiplying torque and reducing inertia in less dynamic applications requiring variable speed control and simple motion control profiles. They are also extremely quiet and many ratios are self locking for holding loads without brakes.
These gearheads are especially attractive when integrated with smaller servo motors, such as those with NEMA 23 and 34 frames as well as similar small metric frames. Even larger servo motors can take advantage of this design with a total of 7 gearbox sizes in the series, with center distances up to 110 mm.
The cost effectiveness of this unique solution enhances the viability of automating many applications that may not be possible with the higher cost gearheads provided by other sources.
