I just got back a 3 phase motor, European WEN motor, back from the rewinder and have a wiring question.
Based on the wiring diagram I have it says.
Speed L1 L2 L3 Typical Connection
High 6 4 5 1&2&3 JOIN 2 WYE
Low 1 2 3 4 - 5 - 6 OPEN 1 DELTA
Can I just use regular contactors to switch speeds or do I need to add a second contactor so that 1 2 3 are joined when I run in high speed? This is a constant torque connection.
Thanks
Richard
