Puddle of electrons collects at bottom of motor, this is caused by gravity.
Put motor horizontal. Or decrease mass of electrons. |

I would think that the unbalance would be caused by unequal phase voltages or unequal motor phase characteristics such as resistance or shorted/damaged windings. How bad is the imbalance? (% motor FLA)
The electrons puddling in the bottom of the motor would pretty much distribute equally causing no imbalance. OTOH a horizontal shaft motor would have the electrons settle to the bottom part of the stator causing a slight imbalance until the motor spun up to speed and the electrons redistributed due to centripetal force. I would think that would happen within a few microseconds of achieving synchronous speeed. |
