Hello All,
We manufacture the dc motors. And for attaching the end frames and the shell, we plan to replace the bolt & nut assembly with the self-threading screws (thread forming).
We use 2pcs of 1/4-20 'thread forming' screw to drive it into a blind hole in the casting. (The thread-forling...

Hello,
I am a mechanical engineer... and I am not very familiar with the MatLab. This is a very urgent project... and I very much need your help...
Question: While working with GUI, I am trying to read a jpg or jpeg file.
All I have to do is...
If I click a push button, I need to display a...
Hello All,
We make dc motors... and for a new application, we need to assemble the blower wheel to our motor shaft and have them dynamically balanced.
The config will look something similar to this...

A quick question to all the pundits out here...
what exactly is it about the larger self-aligning spherical bearing that makes it better than the smaller self-aligning spherical bearing? I've heard a few people here and there mention its superiority, but what I want to know is why.
Is there...
Hello all,
We make dc motors... and as you know, bearing is a part of the motor system. We use 608 ball bearings. Mostly, in the field... the bearings would take the radial (side) load... and a little axial load, depending on the application in which they are used. Right now, we are trying to...
Hello all,
My company makes permanant magnet dc motors... and we are in the process of buying a FEA software.
For CAD modeling, we use SolidWorks... so we prefer to buy the FEA program that is compatable with the SolidWorks. We enquired about Cosmos and MSC... and I am confused on which is...
Could anyone help me to understand how the capacitors aid in the RFI suppression?
reference of notes, technical papers or websites would be very helpful.
Thanks in advance.

Hello all,
In one of our applications, we attach the "metal-graphite brushes" to the "brass terminals" by ultrasonically welding the brush shunts (or pig tail - made of copper braided strands) to the terminals.
This is being a bottle neck operation, because we are having...
Hello all,
We make dc motors. Our customer's requirement is that we pass a 10 G vibration test at 24-1000 Hz frequency ~ the motors being excited along the axis of the motors for 6 hours.
We manufacture shorter stack motors whose armature mass is 1.3 lbs and the larger stack motors whose...
Hello,
Our motors call for a 10-24 tapped hole on the endframes, and a 10-24 screw is driven into it to mount the motors into the unit.Accidentaly, we used a 10-32 screw instead of a 10-24 screw. (Because the torque wrench was powerful enough, this was not inspected during the assembly...

In a nutshell...
We manufacture permanant magnet dc motors... and our motor need to pass the 10G vibration test w/ the shaker table excited at 24 - 1000 Hz.
We have the magnets, attached to the shell using adhesive tape and a clip (clip, as a secondary retention)... which is our only area of...

Hello,
We are manufacturing dc motors... and we are planning to buy a new FEA software to do limited stress & thermal analysis on the endframes.
We use SolidWorks for modeling. So kindly guide me in choosing a proper FEA tool that's compatable with SolidWorks.
Thanks in advance for your help...

Hello, we have an assembly drawing of a motor. One of the subassemblies have wire that we created using the pipe feature. The problem we are having is that in the drafting mode, the centerlines of the pipes show up no matter what the view state is. We have not been able to find a way of...
Hello,
I am a design Engineer at MPOC, and we manufacture "permanent magnet DC Brush motors".
I am trying to come out with an equation to calculate the total heat that is being generated due to the various losses like 1)Winding losses 2)Iron losses 3)Friction losses 4)Brush losses...
