Title: Coils for a linear motor actuator
Post by: jasonhead on May 17, 2015, 04:56:06 PM
I'm exploring an idea for a linear motor actuator, with step control.
If I want to buy the individual electromagnet coils for each control section, what would be best to search for?
The idea is that each coil could be operated separately, and lock the core in place, or be used in sequence to move the core.

What types of inexpensive coils on the market would fit best to build this? Say from ebay etc.

buy magnet wire and wind your own coils

 8) cool concept! n 8)

Your request...

That request is multifaceted in many respects. I do not know where to start..........
To summarize, you want to build a series of electromagnetic cores that work together to
secure movement in a linear fashion to do work.(?)

This type of device is called a solenoid. Now, sequencing multiple solenoids, use phase control,
to multiply work; I have not seen. I have not seen phase control on a solenoid. :o VERY INTERESTING!
Phase control can produce "hotter" power than regular "clean" power.
You could experiment with a solenoid, using a DC drive; The DC drive could be programmed for
any number of phase controls which may result in your desired power control. That would
produce an advantage I have not seen before.(it may already exist, though)
To be more efficient, you could use a PIC controller to produce the desired DC/AC Phase control,
condensing the size of the solenoid. If this works, it could be used to have more power in
robotic hands.(more electronics though!) Interesting; Good Luck!!!!  ;D ;D ;D
