I would like to know if all H-Bridge four quadrant Dc motor driver can regenerate power in braking quadrant.

Hello, I would like to know if the motor efficiency is changing with respect to applied voltage or it doesn't change. What I do mean. The efficiency=(V*I)/(Torque*velocity) and the power...

All textbooks refer to the speed-torque curve for permanent magnet DC motor as a line in first quadrant as in the figure I am asking about what about the curve...

Hello, What do you mean by drooping curve? Could you explain more? Best wishes, Mohammed

Hello, What will be the shape of torque-speed curve in braking quadrant for DC motor? Will it be similar to this curve? Many thanks

What do you mean by "If the voltage is open circuit voltage and the current delivered is limited the battery may not be affected."? Is it possible to charge a...

Many thanks, for those useful information. I have another question what will happen if I charged 12V battery by 40V source or generator. Does the battery charge faster or it...

What do you mean by "What is worse, you may even drain the battery further if a lower voltage source is connected"? Moreover, during charging process do I connect battery...

Does it mean that I could charge 12V rechargeable battery at 5V for example? And, it will charge, but it might takes long time for charging. Is that true? Moreover,...

Many thanks for your help. I would like to know if the varying in charging current has any effect on battery life time. I mean it is better to get...
