Hi all!

Who help me to understand how to carry out conection of Baldor electric motor (see attached)? There are six leads. Its marked two T1, two T2, two T3.

Let me know what should I do to conect motor with star run?

Hello Dimitry,

if connection to be done directly, your nameplate would look the like of:

Attachment 39353

Baldor SuperE is an energy efficient motor execution = good value, so why not contact Baldor directly at

This would be the correct way to do, if you do not have any manuals.

Dear Dmitry,

Probably the motor windings are arranged as follows:;

winding-1 between T1 and T1

winding-2 between T2 and T2

winding-3 between T3 and T3

Check this with an Ohm-meter.

Then, you can connect the phases as Roland indicated.

DELTA:

phase 1 to T1+T3

phase 2 to T2+T1

phase 3 to T3+T2

STAR:

phase 1 to T1

phase 2 to T2

phase 3 to T3

and

T1 + T2 +T3

Then check with the Ohm-meter whether you have 3 equal impedances between the supply connections.

If that is the case, the windings should be correctly circuited.

In case of running in the wrong direction, switch 2 phases.

The motor can be combined with an inverter for constant torque operation between 5 – 50 Hz (approx. 150 – 1490 rpm)

Strong advice

If you are not familiar with electric motors (as your question suggests), leave this to an electrician with expertise and experience and consult with the manufacturer from the motor as well with the inverter supplier.

TAKE CARE
