12 Lead Motor Across The Line

The only time you have to connect a twelve lead motor in both configs is when a wyedelta contactor config is present. I chose a coil as 1 and 2 and hooked one wire to on a 12v battery.

With across the line starting and drives you always use the run delta connection.

12 lead motor across the line. A 12 lead wye startdelta run motor has the ability to meet several starting criteria such as. Startdelta run motor however most motor manufactures have stan dardized with dual voltage motors 230460 which requires the 12 leads to accommodate wye startdelta run on both high and low voltage. Electrical motors 12 lead dual voltage wye startdelta run both voltages or 6 lead single voltage wye startdelta run motors designed by us motors for wye start delta run may also be used for across the line starting using only the delta connection.

Another type of 12 leads wiring configuration which is a distinguished counterpart to the star wye motor connection is the delta configuration. Figure 4 sample motor nameplate diagrams. A twelve lead motor cannot operate in the wye config for any application except for starting.

The standard delta motor has nine leads that are marked t 1 through t 9. Across the line starting on. Figure 4 shows two common connection diagrams for both a six lead single voltage wye delta motor and a 12 lead dual voltage wye delta motor.

I would like to hook the motor up and test but have no idea what coil is what. 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. The 12 lead motor is a very versatile motor and can be connected in numerous ways.

Motor wiring diagram us. The only time you should use the wye connection is a wye delta starter. If you are interested start a discussion page and i.

I ohmd the wires and separated my coils 1 to 6. Wyedelta starting is the most common. The advantage of 12 leads is important due to the motor could run at two diferent voltages 230 v 460 v and could be started in star delta for both voltagesif the rated connection is delta if you will use the motor only for 460 v and will be started with a soft starter or across the line then use a 3 leads motor.

It is a dual speed motor and can be wired as star delta. Nidec motor corporation trademarks followed by the symbol are registered with the us. I have a 12 lead motor here with un marked leads.
