Direct Drives vs Worm-Gear Driven Rotary Stages
- How they are driven
- Comparing two example products to highlight typical differences between them
- Dimensions
- Roughly the same size
- The direct drive in this case is taller
- Loading capability
- The worm-gear driven one can handle higher loads
- Precision
- The direct drive is higher precision
- Speed & torque
- The worm-gear rotary stage produces more torque
- The direct drive rotary stage has a higher velocity rating
- Inertia matching
- The worm-gear stage has more mechanical advantage
- Can handle a much higher inertial load
- The worm-gear stage has more mechanical advantage
- Summary
- Worm-Gear driven
- More industrial
- Larger payloads
- Lower velocities
- Lower precision
- Less costly
- Direct Drive
- Better performance
- Higher velocities
- Higher precision
- Not much more $
- Worm-Gear driven
