In the success one book,they said:"a.c motor continously produces a back_emf limits with the dc motor - the current goes thru the coil. at the beginning the coil If the motor is not driving a load, then the generated back emf will almost balance the input voltage and very little current will flow in the coil of the motor. AC motors are electromagnetic devices that have an alternating current as a power source. Their function is to convert mechanical energy into electrical energy that Electronics Forums > General Electronics Chat Hi, I am trying to understand what effect the induced EMF in a DC and AC motor has on The back EMF is only For AC motors, sine reference means sine output (with control circuit), also back EMF is sine, so the motor purs, but efficiency is low. For BLDC, motor’s back emf waveform on a scope (when driving the motor by some external means) and measuring that waveform, the value for KE can be determined. What is Back emf of DC motor? The backing EMF of a DC motor is the voltage produced in a conductor that tends to neutralize. Why you need back emf in dc motor? Hi, I have a question here. How do I measure Back EMF from a three-phase AC motor? What hardware can I use from National Instruments? &nb

With two coils you can use the Back EMF as AC Voltage. I think 4 coils at 45 degrees then every 90 degrees will give the most AC Voltage back.
