Would there be any problems in feeding a common DC bus via mutiple AC sources, each with its own bridge rectifier. The AC sources would be of approximatley the same voltage (115VAC). For instance utility and UPS AC power sources feeding a common DC bus which in turn powers a DC/DC switching...

Thanks Budt, knowing that device is a pilot operated check valve explains how the circuit works.

EE trying to understand hydraulic circuit, I understand the 2-way valves but the rest is a guess. Energize solenoid A and fluid flows through check-valve on left and out A to actuator. I cannot see how fluid flows out of B circuit? What is that solid black triangle symbol in a rectangle above...

Hello: I have an application where there is a 40 HP submersible pump that is properly installed for cooling flow. The pump is used to pump water from a lake up to a reservoir. The induction motor is a 2-pole Franklin Electric, 575 Volt, 3-phase. The motor is rated at 42.8 FLA with a service...

Hi, I have a problem. I have a pump house at the end of a electric utility line out in the sticks. The utility drops the 14.4 kV single phase (only) to 240 v for distribution. We have a 50 kVA Xfmr to step up the voltage to 480 V. This is feed to a 75 HP Mitsubishi VFD which drives a 40 HP...

I think my windings may be in the wrong direction, should they parallel the axis of the magnet, or radially as shown in pdf?

I am building a turbo prop and I would like to incorporate a permanent magnet machine that could act as a starter and an alternator. I am an electrical engineer, but more on the control side. The best idea I could come up with, remembering that this is a “home built” project, is at this link...

Does stainless ever become magnetized? I am using bearings in a turbine and worry than the 80,000 RPM will magnetize the races. Thanks

What material would work best as core material in a high frequency (>250 KHz) 3-phase, permanent magnet alternator? Thanks!

Thanks for the info! I just discovered "eng-tips" and it is great, I am sure it will save lots of research time. I am a home build aviator interested in building a small turboprop engine (~ 50 kW). The fuel will be jet fuel/diesel and I plan on modulating the air flow to a maximum temperature...

I am intrested in making a burner for turbine. Is there an alloy that has a higher intermittent operating temperature tha 310 stainless?
