For specific Leeson Motor Connections go to their website and input the Leeson catalog # in the "review" box, you will find connection data, dimensions, name plate data, etc. Or will this method ONLY identify the wires … Electric motor wire marking connections. How to correctly wire an Elektrim Motors 12-lead ac industrial electric motor for 230V 60Hz. Speed: Single Phase: 3 Typical Voltage: Dual 230/460 Winding: "Y" Start: "Delta" Run Special Feature: 12 Leads To put it simple, you are applying a lower voltage (wye or "Y") across the motor to start it. First identify combinations. A 12-lead Wye Start/Delta Run Motor has the ability to meet several starting criteria, such as: Across the Line Starting - On the Delta Run connection where the full winding is energized at either high or low voltage. Figure 5.57 is the two-delta connection, which has the lowest voltage rating. 7 Systems Operation Section 6 Lead Delta Connection Illustration 4 g00700323 4 Lead Wye Connection Illustration 5 g00700333. Wire a three phase motor in either a wye configuration or a delta configuration in high or low voltage using a nine lead set up. If the motor … Connecting the soft starter to a wye motor inserts the SCRs directly in the line wiring, referred to as "In Line" wiring. The only time you have to connect a twelve lead motor in both configs is when a wye/delta contactor config is present. Index Of Postpic 2013 02. Arc Flash. Both 9-wire and 12-wire motors can be connected for high- or low-voltage operation. Label the combination of three 7, 8, and 9. October 19, 2018 , 11:40 am , Motor Control, Videos; If you have ever tried to wire up a motor only to find that the motor winding leads in the motor have lost their identification number markings, you know how frustrating that can be. RE: Advantages of 12 lead 460V,60Hz WYE-DELTA Motor over 6 lead 460V motor waross (Electrical) 15 Sep 11 10:04 Most 460V 60Hz motors are suitable for use on 380V 50Hz with no change in connection. But that's OK, because a twenty-four volt motor draws half the current of a twelve volt motor at any given speed. 12 Lead, Wye and Delta Connection Illustration 1 g00700302. ... Its not all that strange to have a single voltage 12 lead motor that ends up being wired as a double Y start or double delta run in the higher hp range. Wye Delta Motor on drive 12 leads only labelled 1-6. Nov 12, 2020. If you find 12 terminals, you need to read the motor name details or specifications to get more info. This is an oversimplification. Friday, January 6, 2017 For induction motors if you run the motor at a high flux level the winding flux magnetizing current has a significant third harmonic content that can flow around the Delta winding without appearing in the lines to the VFD. A twelve lead motor cannot operate in the wye config for any application except for starting. Delta Wye Motor Connection Diagram. Shock & Electrocution. 1.
