No brushes, no sparks, no overheating: the technology that transforms professional tooling and sits at the heart of every Sept Tools machine.
Measured across the Sept Tools brushless range, vs 95 dB(A) on brushed tooling.
Far below the 5 m/s² ELV in EU directive 2002/44/EC: a full day with no MSD risk.
Total protection against dust and projections: compliance for demanding sites.
4,000 to 6,000 brushless hours versus 600 hours on traditional brushed motors.
Constant brushless torque across the full speed range, no stalling.
Electronic variation at constant torque: stripping to polishing on a single machine.
Brushed tooling: 95 to 105 dB(A), pain threshold, neighbours and occupied sites become impossible.
60 dB(A) with Sept Tools: acoustic comfort, sensitive sites and inhabited buildings stay accessible.
Brushed hammer drills and sanders: 8 to 12 m/s², HSE and EU 2002/44/EC limit exposure to 1 hour per day.
0.35 m/s² measured brushless: a full working day without exceeding the regulatory ELV.
Brushes worn out in 200 to 600 hours, costly replacement, machines scrapped prematurely.
4,000 to 6,000 hours without intervention: x10 service life, measured failure rate < 0.8% over 5 years.
Brushed motors that heat up under load: power loss, safety shutdowns, downgraded productivity.
Smart brushless cooling: constant torque under load, no overheating and no cut-out.
Brushes that constantly spark: forbidden in ATEX, ESD and controlled nuclear zones.
Spark-free brushless: compliant with sensitive industrial and nuclear environments.
On brushed motors, dropping to 500 rpm divides torque by 3: the machine stalls as soon as you apply pressure.
Constant brushless torque from 500 to 4800 rpm: variation < 5% under identical load.
No brushes, no carbons, no mechanical friction. Everything is driven by dedicated power electronics.
The rotor carries very high energy neodymium magnets, with no brushes and no carbons.
Three Hall sensors read the rotor position in real time, 60,000 times per minute.
The controller calculates the energising sequence of the stator windings based on the position read.
When resistance increases, the controller raises the current to preserve nominal torque.
No mechanical contact between rotor and stator: 4,000 to 6,000 hours of service life.

Measured variation < 5% under identical load. Stripping and polishing on the same machine.
Compliant with non-explosive ATEX zones, ESD and controlled nuclear environments.
4,000 to 6,000 hours without intervention. Failure rate < 0.8% over 5 years of intensive use.
Total dust and water sealing: high pressure cleaning accepted.
Vibration 0.35 m/s², 60 dB(A), controlled weight: engineered to reduce MSDs.
Designed, assembled and tested in France. National aftersales, spare parts in stock.
