Here α (alpha) is the angle between the plane of the armature turn and the plane of reference or the initial position of the armature which is here along the direction ofmagnetic field. The presence of the term cosα in the torque equation very well signifies that unlike force the torque...
The working of the AC motor (Induction motorandSynchronous Motor) is different from theDC motor. A Simple 2 Pole DC Motor There is no basic difference in theconstruction of a DC generator and a DC motor. In fact, the same DC machine can be used interchangeably as a generator or as a ...
The working principle of a DC generator is to convert the alternating electromotive force induced in the armature coil into a direct current electromotive force when it is led out from the brush end through the commutator and the commutation action of the brush. The direction of the induced elec...
2. The excitation winding of a parallel excited DC motor is parallel to the armature winding, and the wiring is shown in Figure (b). As a parallel excitation generator, the terminal voltage generated by the motor itself supplies power to the excitation winding; As a parallel excited motor, ...
Working principle of DC motor:- A magnetic field arises in the air gap when the field coil of the DC motor is energised. The created magnetic field is in the direction of the radii of the armature. The magnetic field enters the armature from the...
What is the working principle of the spectrometer? What is the principle involved in the Sonometer experiment? What exactly is the superposition principle? What is an electric motor? State its principle. What is the principle of an electromagnet?
What is the working principle of a dc generator? It is the alternating electromotive force that induces in the armature coil, so that it can be changed from the brush end to the direct current electromotive force. The direction of the induced electromotive force is determined according to the ...
the permanent magnet is rotating whereas the windings are part of the stator and can be energized without requiring a commutator-and-brush system. The commutation of the brushless DC motor is made electronically and can be done either by looking at the back-EMF of the motor or by using a ...
An alternator operates on the same fundamental principle of electromagnetic induction as a DC generator. The working of an alternator is based on the principle that when the flux linking a conductor changes, an emf is induced in the conductor. ...
aIts working principle is to power frequency alternating current (ac) by rectifying equipment transformation into direct current (dc), through the inverter the dc into frequency adjustable alternating current (ac), which changes the mechanical speed of the motor. 它的工作原理是通过矫正设备 (变革) ...
