The heart of our MICROMOT precision tools for 230V is a comparatively more expensive direct current (DC) special motor.

In relation to its size, the permanent magnet technology makes it very powerful, quiet
and long-lasting. Due to its very high efficiency, this motor requires considerably less

power for the same power output from the socket outlet than other commonly used
motors.
Of course, when utilizing these motors our first concern is to produce small, slender tools
with high performance. The outstanding ratio of current consumption:power output also
contributes significantly to energy saving, thereby also protecting our environment !
