Outrageous Dual Voltage 3 Phase Motor

220 240 vac 3 phase.

Dual voltage 3 phase motor. It s not that complicated. This video will walk you through the standard winding terminal designations proper wiring connections and expected winding voltages for a dual voltage 3 phas. I am trying to understand how the different wiring is changing the way the windings get current.

Many 3 phase motors allow for two possible line voltages for example 230 460. Typically the motor has three six nine or twelve external leads depending on what the motor was designed for. Bryan is back with more of his knowledge this time about dual voltage and part start 3 phase m.

For three phase induction motors the windings are connected in either a wye or a delta configuration. A common connection for this type of motor contains two run windings and one start winding figure 11 17. Three 3 phase electric motor dual voltage.

These motors are designed to be connected to 120 or 240 volts. Don t get overwhelmed with 3 phase. This video will walk you through one of the methods used to determine the wire numbers on the 9 leads of a dual voltage three phase motor when for some reas.

The start winding is labeled t5 and t6. In the circuit shown in figure 11. In a three lead motor only three terminal leads are brought out of the motor.

The run windings are labeled t1 t2 and t3 t4. If you want to chip in. I have received several requests to cover this topic.
