The PROXXON hand-held Rotary Tools have a special high-revving permanent magnet motor, which offers high speeds as well as lots of torque even at low speeds. This motor is specially balanced and runs quietly and without any vibration at all. The motor is by far slimmer than a standard universal type motor, which is generally used in power tools and thus allows Proxxon to design handier and more manageable tools. The long lifetime of the motor (without the need of replacing motor-brushes) ensures hassle-free application.
This professional rotary tool by Proxxon is capable of extended continuous use without protest. The motor (100W) has full-wave electronic speed control producing continuously variable speeds between 5,000 and 20,000 rpm and is designed to be used for extended periods at a time.
