Stator Ring Connection Question

I am constructing a steel stator ring with 6-coils powered by 3-Phase AC power. However, I am unsure as to how to connect the three wires of the interconnected 6 coils to the AC power source to get a rotating magnetic field. Is there a certain automated switch that will change the AC coming out of a

Stator Field Coil Windings

I am trying to find a program or formula that will help me figure out how many windings, turns of coil, are needed per coil on a 6 coil steel stator ring powered by 3-phase AC power to get a certain magnetic field strength, about 1.3T. Is there any way that you could help me find out how many windin

Solar Panel Spacing

Greetings All,

I'm trying to build a 1.5Mw solar farm, PV, fixed ground mount, and the engineers say that as a rule of thumb they just space the rows 2-3 times the max height of the panel (because of the shadow). I did the math and found I could space them 7 feet apart without causing shading,

Heat Exchange

Question for anyone,

When dealing with water supply and return for induction coil boxes, does piping and hose size matter and what is the normal procedure for such an application? Let me know if more information is needed.

316 or 316L Dual Certification

Hi Friends,

We require SS 316L material for some vessel welded internals due to H2S Service.

Shall I go for SS 316 material for internal bolt item which may not require welding.

Is there any requirement to go for dual certified bolts (SS 316 / SS 316L)...

Is it required?
