At the heart of the PEMSERTER® 3000 press is a custom built, full servo controlled, electro-mechanical actuator that provides many features for faster, cleaner and more energy efficient operation.
These features include:
- Roller screw instead of roller ball technology can carry larger loads and higher speeds more efficiently.
- Optimized coil construction reduces the physical size of the actuator, increasing motor efficiency.
- No hydraulic oil. The system is sealed and lubricated for life which eliminates environmental issues and maintenance costs.
- Dual axis actuator technology allows for ram speed optimization, high pressing forces and extremely low energy usage.
- Specialized clutch system provides smooth energy efficient transition between servo axes.
- After initial PC setup, all run logic is maintained in solid state servo controller memory. This uses much less power than normally necessary to operate total PC run systems.
- The ram is accelerated and lowered to the high force position using primarily gravity, requiring very little energy,
- Regenerative/Dynamic braking captures the inertial energy and re-applies it to deceleration and braking of the ram as it returns to the top home position. This substantially lowers the external energy requirements of the system.
- Gear reduction and short high force pressing distance require very little energy consumption.
Energy Usage Estimate Comparison to a Hydraulic Press
The PS 3000 press running at 40 strokes per minute can produce 4,992,000 insertions at a cost of approximately US $39.00 per year. Comparably, a typical 8 ton hydraulic press running at 15 strokes per minute can produce 1,404,000 insertions at a cost of approximately US $863.00. To run a hydraulic 8 ton press to produce the same amount of strokes as the PS 3000 press would cost approximately US $3,068.
PS 3000 press energy usage is based on straight line calculations derived from an independent study conducted by a reputable testing house. Below is a summary of energy usage at different force values and cycle times.

* All calculations are based on an energy cost of $.1 per kW/hour. This is a very low cost of electricity. Higher electricity costs would equate to even greater cost savings
