May 14 2016 I was wondering if there is a motor/generator design where the rotor moves gradually in and out of the stator along the axis of rotation or the stator moves over the rotor. If so I d like some mechanical engineering electrical

Mar 20 2013 The field winding of DC motor are made with field coils copper wire wound over the slots of the pole shoes in such a manner that when field current flows through it then adjacent poles have opposite polarity are produced. The field winding basically form an electromagnet that produces field flux within which the rotor armature of the DC motor rotates and results in the

Aug 17 2020 The working of AC car alternator is quite simple and less complex. It contains two windings such as a stator stationary outside winding and a rotor rotating inner winding . The voltage regulator supplied voltage to the rotor winding which energizes and turns it into a magnet. Via a pulley the rotor is rotated by the engine through a drive belt.
The rotating part or rotor is the armature. The stationary part or stator is the armature. The stationary part or stator is the surrounding magnetic field. The generated output current is taken from the stator. The generated output current is taken from the rotor. The output voltage of Alternator is always higher then Generator.

However simply changing from an outer rotor type to an inner one does not make it faster by itself. In addition the rotor diameter was decreased to control the moment of inertia the stator side coil thickened to increase current the number of windings increased and the air gap between the stator and rotor made as small as possible.

Use steel wool penetrating oil and some 500 grit sandpaper to clean the pins and the inner holes on the caliper. Clean the entire unit. Then apply a generous brushing of anti seize compound onto each pin and tap them with the bolt and hammer back into the holes. Reassemble center armature and put spring back on.
Aug 02 2018 Note that those four pieces the stator the rotor the regulator and the rectifier can be packaged together or separately. The stator and rotor are usually cheek by jowl because of the need for one to rotate ‘round the other. Note that collectively a stator and a rotor make up an alternator which is a type of generator.

The outer tube carries the rotor driven by electrostatic electrodes rotating around an inner tube which acts as a supporting shaft. By applying voltage pulses of up to 5 Volts between the rotor plate and stators the position speed and direction of rotation of the rotor can be controlled.

The air gap is the space among the stator and the rotor. The effect of the air gap mainly depends on the gap. It is the major source for the low power factor of the motor. Once the air gap increases between the stator rotor then magnetizing current also increases. Because of this reason the air gap should be less. Windings

The stator then is the stationary part of the AC motor. The rotor is the rotating electrical component. It also consists of a group of electro magnets arranged around a cylinder with the poles facing toward the stator poles. The rotor is located inside the stator and is mounted on the AC motor s shaft. The term rotor is derived from the word
