Typical areas of application of three-phase AC motors
Use of the following sections
The following sections 2.5.1 to 2.5.5 summarize the typical characteristic
values. They provide an overview of the performance capabilities of the
various motor types. Selection of the motors, dependent on application, is
presented in sections 3.3 to 3.6.
Motor type
Working
principle
Application
Standard three-phase
AC motor
asynchronous
In all industrial sectors. Around 10-15% of all
motors are speed-adjustable by way of inver-
ters.
Synchronous motor synchronous
In the textile industry for: Spoolers, viscose
pumps, galette drives, 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 or roller motors, 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.
