With an electric screwdriver, you can sustainably save over 3,000 m3 of air consumption per year. With an average consumption of approx. 6.5 kWh/year, you reduce your costs with the same screwdriving performance.
Example calculation:
Screws per day | Pure screwdriving time per day | Working days per year | Air consumption m3 / year | Electricity consumption kWh / year | Costs € / kWh | Costs € / year | |
Pneumatic screwdrivers | 4,800 | 2 hours | 225 | 3,240 | 356.40 | 0.15 € | 53.46 € |
Electric screwdrivers | 4,800 | 2 hours | 225 | -- | 6.5 | 0.15 € | 0.98 € |
A brushless motor is an electric motor without carbon brushes, that is, without sliding contacts. In brushless motors, there is no electrical contact between the moving rotor and the stationary stator.
A brushless electric screwdriver is necessary:
- When used in cleanrooms
- When assembling sensitive or electrical components
- In ESD environments
- For > 500,000 screwings per year
Other arguments in favor of brushless technology:
- Brushed technology is no longer being further developed in screwdriving technology
- Less downtime due to time-consuming maintenance work
- Almost no price difference between brushed and brushless technology
Maintenance costs brushed | Maintenance costs brushless | Screwings | Explanation | |
1st year | -- | -- | 500,000 | First pair of carbon brushes included with each screwdriver |
2nd year | approx. 375.00 € | -- | 1,000.000 | New motor with new coals required |
3rd year | approx. 18.75 € | -- | 1,500,000 | New carbon brushes required |
4th year | approx. 375.00 € | -- | 2,000,000 | Next motor change necessary |
Lever start system:
The electric screwdriver is started by pressing the start button by hand.
Push start system:
The electric screwdriver starts by pressing the screw on the screw head.
