DC motor torque-speed chart in braking quadrant

AI Thread Summary
The torque-speed diagram in the braking quadrant of a DC motor is characterized by negative torque values as the motor operates in a regenerative braking mode. This quadrant typically shows a linear relationship similar to the motoring quadrant but reflects the motor's ability to convert kinetic energy back into electrical energy. The equation for this quadrant can be derived from the motoring equation, but with adjustments to account for the direction of torque and speed. Understanding this diagram is crucial for applications involving braking systems in electric vehicles and industrial machinery. Further research into regenerative braking principles may provide additional insights into the specific shape and characteristics of this diagram.

What is the context of the question? What reading and research have you done so far on this question?
 
All I found is the torque-speed diagram in motoring quadrant. Which follows the following equation : Torque=C1-C2*speed. I am asking what about braking quadrant?
 
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
