Sir if the current decreases in the armature conductor due to back emf then the force or torque acting on the conductor will also reduce right.then armature conductor will have low magnetic field and hence low rotation. (I am confused with the rotation why doesn’t it decreases if the current in armature refuces)

@ABINASHHANDIQUE12 Жыл бұрын

Because flux is responsible for torque...flux is proportional to toque but current is indirectly proportional to torque

What is a dc motor? What is back emf? Isn't it wonderful that when we flip a switch which is wired to a ceiling fan, the fan rotates! Take a moment to visualize the force which acts on the blades to keep them rotating while we are standing on the floor far below the fan. As if it is rotating by an unseen hand! It operates based on the principle that a current-carrying conductor placed in a magnetic field experiences a force and this is what was encapsulated in the Lorentz force law. A description of load torque always accompanies a discussion on motors. The effect of its imposition on motor torque, and how this causes the motor to draw power from the power supply then follows. The phenomenon of how it is the ‘back emf’ in motors, which regulates the motor torque to match load torque completes the discussion. To understand these ideas, it would be instructive to understand Current, the conduction process and Voltage at the fundamental level. Electrostatics and circuits belong to one science not two as in the following two videos: i. kzfaq.info/get/bejne/irqkp5Vpx5fIiaM.html and ii. kzfaq.info/get/bejne/bqiBgMKp3Ji2lqM.html The "back emf" or "motional emf" is a trick nature uses which has a regulating effect in determining the amount of current the motor draws and is a natural consequence of the induced emf process when a conductor moves in a magnetic field. The fan pushes air and the molecules of air when they leave the blades produce a reaction force, a torque as the blades spin. The fan motor should generate sufficient torque to overcome this opposing “load” torque and keep the blades spinning. The "back emf" regulates the current to generate this required torque automatically! The governing relation for current in conductors is J = σE_net where σ is the conductivity of the conductors and E_net is the resultant of the applied and inducedcelectric field components in the conductor. It is not possible in this post to discuss in more detail the process of production of the back emf and its regulating effect on motor torque. The last frame References in video #1 lists textbooks 3 and 4 which discuss these topics in more detail using a unified approach and provide an intuitive understanding of the generation of an emf in generators and motors.
