why it is used wound rotor motor in cement mills

What makes thewound rotor motora unique induction machine is itsrotor. Instead of a series ofrotorbars, a set of insulatedrotorcoils isusedto accept external impedances. Therotorwindings are similar to those found on a DC armature, with the coils connected together to a set of rings that make contact with carbon-composite brushes.

Aug 02, 2018· Brushed DCmotorsare generally available in two types, depending on the construction of the stator: permanent magnet orwoundfield. Bothmotortypesusecurrent and windings to produce a magnetic field in therotor, but they differ in how the stator magnetic field is produced: via permanent magnets inside the stator or with electromagnetic windings.

What is aWound Rotor Motorand How Does it Work?

Aug 13, 2020· Inwound rotor motors, therotoris “wound” with wire similar to the stator, with their terminal ends connected to 3 slip rings on the output shaft. These slip rings are attached to brushes and variable power resistor banks, where operators can change the speed of themotorby varying the resistance through therotorcoils.
