Application
Standard three-phase 
AC motor
asynchronous
In all industrial sectors. Around 10-15% of all 
motors are speed-adjustable by way of invert-
ers.
Synchronous motor synchronous
In the textile industry for: Spoolers, viscose 
pumps, galette drives or roller drives etc.
Further areas of application are in the glass 
and paper industry as winding drives, etc.
Reluctance motor
asynchronous/
synchronous
In the textile industry for: Spoolers, viscose 
pumps, galette drives or roller drives etc.
Further areas of application are in drafting 
equipment and for synchronous running of two 
axles.
High-frequency motor asynchronous
In the timber processing industry as the main 
drive. Further areas of application are grinding 
and milling spindles, centrifuges, vacuum 
pumps and winders.
Asynchronous 
servomotor
asynchronous
In the packaging and food industries as a clock 
and positioning drive. Further applications as 
the main drive for machine tools.
Displacement-type 
armature motor
asynchronous 
with motor brake
In conveyor systems as a traction and lifting 
motor.
