Supreme 12 Lead Motor Across The Line

They are generally held to a standard.

12 lead motor across the line. Wye connection single voltage. Units rated for single voltage may have 12 leads and be suitable for wye delta or part winding starts. If he has any questions.

12 lead dual voltage wye start delta run both voltages or 6 lead single voltage wye start delta run. The final connection of the motor is ultimately the responsibility of the installing electrician. Damage will occur if the motor is operated with load for more than 30 seconds on the wye without transition to.

Wye start delta run or pws connection 12 lead dual voltage. Although this increases the time required to test every possible combination. If leads are numbered 1 to 12 the motor is typically rated for two voltages and could be used with a wye delta starter at either voltage or a part winding starter for low voltage only.

Delta connection single voltage. Wye connected 12 lead motors differ from 9 lead three phase dual voltage motors in that none of the coils is permanently connected and therefore all can be tested separately. Star config for one voltage and delta for the other.

As long as your wires are numbered you are all good. This is a 12 lead motor not a 9 lead motor. The only time you should use the wye connection is a wye delta starter.

Motors designed by us motors for wye start delta run may also be used for across the line starting using only the delta connection. If used on a standard across the line starter soft start or variable frequency drive these motors should be wired in the delta run connection for either high voltage 480v or low voltage 240v. If a multimeter shows continuity between leads 7 8 and 9 the machine is wye connected see fig.
