That means there are 4 poles for EACH phase, or 12 sets of windings on the motor. Each phase goes to 4 windings in series. (You might call this a 12-pole motor, but electrical engineers group these together and call it a 4-pole motor.) If you apply current to one phase, the motor will "stick" in two positions.

It contains a definitive record of application performance, security threats, fraudulent activity, and more. Splunk takes this data and makes sense of it. IT sense.
