Aug 27 2021 During starting residual flux in the rotor body induces voltage in the stator current flows through the capacitor. Handbook Insulating materials The reason using insulating materials separate electrically the conducting equipment from
Apr 01 2000 The rotor here is like the nail in our previous example and the stator is like the horseshoe magnet. When DC power is sent through the rotor it creates a temporary electromagnetic field that interacts with the permanent magnetic field of the stator. The commutator s job is to keep the polarity of the field flipping which keeps the rotor

motor. The rotor has salient poles and a cage so that it starts like an induction motor and runs like a synchronous motor. 2. Uses soft magnet rotor that is magnetized by the application of current in the stator coils 3. The magnet is spun by a 3 phase AC motor with no rotor voltage 4.
The elastomeric stator is bonded to a tubular steel housing Figure 26 2 . The multi lobe form is helically screwed along the length of the stator. The steel rotor is produced with matching lobe profiles and a helical pitch similar to the stator but with one less lobe. This allows the rotor to be matched and inserted in the stator.

Mar 14 2020 The rotor has two or more arms lobes that hold the conductors. They are called armatures and the conductors wound around them are called rotor or armature windings. The armature windings terminate in electrical contacts that commute the current to the output terminals. That section of the rotor is called the commutator.
The permanent magnets are the stator and the rotating armature is the rotor. In the armature is an electromagnet that when powered by electricity creates a magnetic field that attracts and repels the magnets in the stator. This allows the armature to spin just 180o.
In some applications such as electric vehicles electric motors should operate in a wide torque and speed ranges.

Sep 02 2016 Rotor may be striking stator. Ensure that motor was not damaged in shipment. Frame damage may not be repairable. If you cannot see physical damage inspect the motor’s rotor and stator for strike marks. If signs of rubbing are present the motor should be replaced. Sometimes simply disassembling and reassembling motor eliminates rubbing.
