When we pulse a coil, we create a pulsing magnetic field and we can recover most of the energy in that coil using http://www.energeticforum.com/renewa...-circuits.html
We get losses based upon the resistance of the wire and this can be measured in the rise in temperature. My question is, does the magnetism cost us any energy or is it a free byproduct?
In a normal motor we get increased power draw because a motor slows and generates less BEMF. If we pulse a motor that produces BEMF we still have the problem of putting energy in to overcome the BEMF but I haven't been able to work out if the magnetism is costing us anything.
Most Info that I have found says the energy input is converted to torque in the motor and assumes no recovery, but when we recover the pulses should the torque drop?
