General stepping motor phase current 3 phase induction motor is the current (or resistance), is the current value of each group of coil (or resistance), if two phase six diesel generator wire stepper motor using the first connection, equivalent to two sets of coil together, so each phase resistance increased, the water pump price rated working current is reduced, even if the drive is set to the nominal current also rated output value of every phase. So when choosing drive and stepper motor current matching problems. Accurate method is should set drive output current to stepping motor phase current of 0.7 times the rated (also not often assume that a series of current in half). For example, such as A two phase stepper motor with A center tap, nominal current is 3 A, drive current should be set to 3 * 0.7 = 2.1 A.
