WebFeb 25, 2015 · Due to floating neutral, the phase to phase voltages keep on changing with different loads. If the neutral is solidly grounded and any of the phases get earthed say Y ph (ie at 0- potential) the voltage of healthy Phase to neutral shall remain as it … WebAs described in theory the Back EMF of floating phase ant any instant should ramp up or down but why there is a huge spike? How to reduce the spike? It is demagnetization of the phase winding, as low side fet is off and high side diode is conducting. My second question is at lower rpm why there are so much noise in back EMF?

Floating grounds can be dangerous if they are caused by failure to properly ground equipment that was designed to require grounding, because the chassis can be at a very different potential from that of any nearby organisms, who then get an electric shock upon touching it. Live chassis TVs, where the set's ground is derived by rectifying live mains, were common until the 1990s. Exposed live grounds are dangerous. They are live, and can electrocute end users if touched.
