    AC Synchronous Motor Question

    I have a 3755HP 6600V AC Synchronous Motor and I was wondering if it is ok to run this motor at a stator voltage of 4160V continuously? Are there side effects of operating a synch motor at lower than rated stator voltage? The excitation requirements for this machine is taken care of fully so...

    Questions for Mechanical engineer technologist

    Why don't you go and get your MSME? I have a ABET accredited BSEET and I was accepted and graduated 2 years ago with my MSEE without taking any extra classes.

    Motor-Generator Set Bolted Fault

    The source of excitation is a brushless exciter. Unfortunately the name plate on the generator just states that and for Field Voltage and Field Current it states N/A. Thanks for all your help.

    Motor-Generator Set Bolted Fault

    Hi, I have a 30hp 39A @ 440V 3 phase AC induction motor turning a 20kVA 58A @ 200V synchronous generator. My question is how could I calculate the line current into the AC motor if a fault was to occur on the generator output? I have asked the manufacturer of this M-G set for this information...

    DC Link Inductor Calculation

    I am interested in wondering how to determine the inductance of a DC Link Inductor I am using in my system. I have a 12 pulse source bridge, two 6 pulses in series with each 6 pulse receiving 230VAC. A wye transformer for one 6 pulse and a delta transformer for the other. The DC link inductor...

    Used AC Synchronous Motor

    My application is a smaller version of a full size 4160V 3 phase ac generator. I am using a 12 pulse LCI to power this motor. We have at our company a 240V 3 phase AC synchronous motor but the transformer we have for the 12 pulse LCI is for a 460V AC synchronous motor. It needs to be synchronous...

    Used AC Synchronous Motor

    Hello, Does anyone know of a company that sells used motors? I am in the market for a 15-25hp 460V AC Synchronous Motor. Any help is appreciated. Thanks, Joe

    Company paying off student loans

    4K/month after taxes, 401k and medical coverage deductions? That would mean you would be getting ~70-75K annual salary, right out of college with a BSME????? I have a MSEE with some experience and I am no where near that. Make sure you have your calculations right before you start buying...

    LED Lightbulb

    How does a LED lightblub that screws into a standard lightbulb socket work? Is there a brige rectifier that changes the 120VAC to some DC voltage and then the LED's are connected in series for an appropriate voltage drop? Following Link is an example of the product I am discussing...

    Residential Power

    There seems to be some controversy on the internet wherever I check on how 240 volts is brought into your house. Some sources say that the electrical output of the transformer on the power pole is a 3 wire single phase, or others say it is 2 single phase 120V that have 180 deg of phase...

    Turn my BSEET into a MSEE

    There are schools out there that allow BSEET degree holders obtain a MSEE. I know because I have my BSEET and am currently 3 classes away from my MSEE. It is going to be difficult though to find a school that will be able to work with your schedule. Most graduate schools hold classes at...
