Sirona Seriotorque Brushless electric handpiece motors have been graded one of the best by users. Very light which translates to quicker transition from air driven handpieces. Also, see the Sirona Electric page for attachments to accompany these.

Brushless, compact and extremely powerful!
The SIROTorque L+ is the perfect electronic unit for the BL and BL ISO brushless micromotors. This compact table top can be quickly and easily integrated into any treatment unit with air and water supply. The SIROTorque L+ provides continuous, quiet and smooth operation through the entire motor speed range of 90 to 40,000 rpm, even with quick changes in motor speed. This allows you to operate in a working range of 4 to 200,000 rpm without any unpleasant noise!

Easy installation and operation!
Unlike competitors’ products, which often initially require time-consuming calibration to the unit, the SIROTorque L+ is calibrated automatically. Treatment can begin immediately and without any delay. You also have full control when operating the system during treatment: the whole range of motor speeds are monitored and shown on the clear display. This is also the case with handsfree operation using the foot control. The display keeps you well informed and ensures optimum reliability during treatment!
