We are a manufacturer looking to redesign an electric motor that we currently produce. It is a 2hp 3phase squirrel cage design and we are interested in something with 3-5 HP. Can anyone recommend a good consulting service or another good first step? We have been checking with a few lamination...
We manufacture a three phase induction motor, 230VAC, 250 Hz. It operates on a VFD for variable speeds. Normal operation is about 200 Hz and 200 volts. The proper ratio for the drive is about 1:1, Hz to Volts.
I have a overseas customer asking the following question:
Are the windings strong...
Looking for a motor shaft steel that can be case hardened and will resist breaking from fatigue/vibration. We've been using 316 pre hardened stainless steel. But I'd like to get something with higher iron content. Leaning toward 1144 or 4140 any input is much appreciated
We currently manufacture a specialized, compact 2 hp, 230 VAC three phase induction motor. It is designed for variable speeds up to 250 Hz, or about 15,000 rpm. It runs at about 2.5 amps, no load at this speed and requires only about 15psi air to operate under a working load of about 5.5 amps...
We manufacture a specialty compact 2hp induction motor with variable rpms-- approx. 1800 rpm - 14,000. We need to make the motor waterproof. We have had only limited success with a lip seal and the mechanical seals I've seen are not capable of these high speeds. In fact we would like to adapt...
We manufacture a specialty elec. motor that requires the shaft to have good magnetic properties but we also need good corrosion resistance. We've been using 416 stainless steel (7/8" rod). but it is not standing up to the corrosion of the salt water environment.
Question: will 17-4 stainless be...
We build a high speed 3ph 220vac inductive motor using a rotor with copper bars and end rings (about 1.5" in diameter). Historically we have used C110 copper for the end rings but it is terrible to machine and drill. I would like to switch to c145 as it is much easier to machine. Question: is...
We are build our own custom 240 vac 3 phase inductive motor in our shop from scratch. This is a 2 hp small motor that is only about 3 1/2" diameter by 8" long. Last week we built a 480 volt version of the same exact motor, and it has drawn very amps.
We have checked and re-checked our...
After months of hard work, we tested our second prototype motor today with disappointing results. The motor amp draw is too high and the motor shaft quickly overheated. The problem was determined to be the stator laminations with a
c5 coating not providing enough insulation. We will try...
