The strange thing which is different from the first picture which @MotorWinder showed (4 pole, Delta connected, Part winding, Adjacent Pole, 2 Circuit), is that there are connections with 3 leads. ... Part-winding motors don't do well with only one set of windings energized for more than a few seconds and even worse with the other set shorted as they would be … It can be connected two wye to start and two delta for run (operating on the two-delta voltage). This type of motor requires no connection diagram because the electrician simply connects the three motor leads (which may be labeled T1, T2 and T3) to the respective starter terminals, which connect to power supply lines, L1, L2 and L3. It can also be connected one-wye start and one-delta run (operating on the one-delta voltage). Pumping is the most common application for a part winding start. Feb 27, A lead Wye Start/Delta Run Motor has the ability to meet several starting Wye Delta Starter or by a series of contactors in a control circuit.Motor Wiring Diagram 12 Lead, Dual Voltage, Wte
