The laboratory micromotor is the dental technician's usual working tool.
The SR 450 'Twister' micromotor was developed by us due to the increasing request for a light but powerful and reliable tool that could be used in any work in the dental laboratory, but especially for the processing of hard metals (chrome/cobalt alloys) and ceramics.
The laboratory micromotor consists of 2 parts: the Handpiece and the feeder.
The handpiece is equipped with a low-voltage (Brush-less) electric induction motor (32 V AC) which makes the spindle rotate through a transmission coupling.
The spindle is equipped with a chuck that can clamp a tool (cutter) with a shank diameter of 2.35 mm.
The brush-less motor allows high rotation speeds (3000 to 40000 rpm) while maintaining a high working torque.
The feeder consists of a transformer and an electronic control that feed the motor with a low alternating voltage at a variable frequency that allows it to adjust the operating speed and to regulate and compensate the working torque, so that it can work efficiently even at low speeds
VERSIONS
