Linear motor, actuator - Contamination??? Magnetic Particles
Linear motor, actuator - Contamination??? Magnetic Particles
(OP)
I am specing out a linear motor.
there is going to be a lot of fine ferrous metal particles and i am concerned with the magnetic properties of some of the drives, that the motor will be a huge magnetic science experiment.
Has anyone had experience with this?
Thanks in advance

i'll look that up
i am worried that unless i choose a timing belt driver or ball screw style linear actuator, i'll have a major collection point for debris, i do however like the cleaner lines of the magnetic driven actuator

reciprocating motion
almost like a long stroke jack hammer
duty cycle of 50%
repeatability to within 5 thou
(and i would rather not get into a hydraulic pump, etc.)
the heat generated and seal life at high repeated speeds would have maintenance issues

You might want to look at www.powerjacks.co.uk if you fancy the electric solution. Failing that, www.rexa.com have some nice self-contained hydraulic packs to which you supply power and a 4-20 mA demand signal. The oily bits are not something you need to get too involved with. Moog have something similar but their sales guy in the UK pissed me off so bad that I can't be bothered with them even though I like the build quality of their products.

The bell crank needs to have total adjustability in terms of stroke length and stroke position (over 42"), for this application, i dont think something like that will work
