Web6 mei 2024 · If you stall a motor there is no back EMF so typically very large currents flow as there is only the winding resistance to limit it. However there is no easy way to measure back EMF as the voltage at the terminals is the sum of this EMF and the voltage drop across the resistance of the windings. Web27 okt. 2011 · As the motor is loaded, the back EMF shifts such that it will be more in line with the driving voltage/current for that phase.
