Neat 3 Phase High Voltage Motor Wiring
As in if you have a 230460v motor the high voltage connection is for 460v incoming service.
3 phase high voltage motor wiring. The first step is to figure out the voltage of your phases. Motor wiring diagram 12 lead single voltage wye start delta run or part winding start revised. A 9 wire motor can only be connected.
If you have 230 volt three phase you have to wire the motor in the lower voltage configuration. It also shows the difference between delta and star connecti. L1 to t1 l2 to t2 l3 to t3 t4 to t7 t5 to t8 and t6 to t9.
If i have a question that asks how to wire up a motor that has available leads of 208 volt 3 phase. That being said there is a wide range of different motors and what you have on hand can be completely different. But this is a wye system so i assume its.
The other 9 wires would be connected as in a 9 wire motor note in a 9 wire motor the equivalent of t10 t11 and t12 are internally connected together. 1 8 nidec motor corporation. In a delta configuration the outlet of one winding is connected to the inlet of the.
208 is low voltage correct. Three phase see below single voltage. Smiths line of century motors.
Sometimes you apparently need to rewire a 3 phase motor for low voltage 230v as opposed to 460v in order to connect the motor to a vfd. Smith uses cx to identify its. Anyone whose job involves servicing electric motors has encountered the problem of a missing nameplate.
