Dear Vertical Axis Readers: Controls don't have to be expensive. Microstar Laboratories www.mstarlabs.com makes some excellent PID controls via their real time data acquistion co-processors. Today's ghtz speed microprocessors now allow for PC based control systesm with data acqusition processors from the likes of Microstar Labs and others at a fraction of the cost of more traditional control systems. All you need to do is several things:
1)How channels you need to control. 2)What is the sampling speed per second per channel? SOme call this the bandwidth. 3)What resolution do you need (16 bit, 14 bit?) 4) What type of processing? In this case, the rotational angular velocity can be controlled via a analog to digital encoder. I have some buddies at Microstar Labs and you can send your questions to their Application Engineers at [EMAIL PROTECTED] Other - Lubrication Since I am a mamber of the Society of Tribologists and Lubrication Engineers, I will ask my Lubricant Engineering associates for their opinion on the proper lubrication for worm gears and other gears in rotational torque movements.
