4.5 Drive and Stirrer
Stirring is carried out from below using magnetic drives. Stepper
motors and speed monitoring are used to ensure compliance with
the specified stirrer speeds.
For speed ranges, see the chapter "Technical Data".
The power is transferred via ring magnets. Two are located on the
drive shaft and two on the encapsulated motor shaft below the cul-
ture vessel in the basic unit.
