AUMA SA10.1-13A Electric Motor Actuators (2 of 4)

If the drive shaft is to be positioned at a certain angle to the output drive shaft or if the direction is to be displaced by 90°, combinations of the multi-turn actuators SA ... with AUMA spur gearboxes GST or bevel gearboxes GK are used. In both cases, the output torque can be increased many times.

  • Torque range from 120 Nm to 16, 000 Nm
  • Handwheel for manual operation
  • High enclosure protection
  • High quality corrosion protection
  • Wide ambient temperature ranges
  • Electrical connection via AUMA plug/ socket connector (optionally terminals)
  • Plug cover with threads for cable glands
  • Output drive types according to ISO and DIN standard

The applications for linear motors and linear actuators overlap, so maybe you can use a linear actuator
The latest issue of the catalog from American Science and Surplus, also found at , has a few linear actuators, but they are 12 volt, and cheap.
Similar, more expensive, units are found at the surplus giant Herbach and Rademan who have an online catalog
Personally, I would order by mail, rather than drive anywhere in S.F.
good luck

Your grid tie inverter

2006-11-07 17:40:58 by solarmandotorg

From what i gathered from google, your inverter probably does use MPPT (maximum power point tracking).. read your manual and make sure though.
like i said, seasonal tilt makes a huge difference. you have about 3 times the panels i do. i leave mine in place but i can move them in about 10 minutes and that includes dragging the ladder out.
you could even set up some linear actuators to move them up and down. these are the things that swung the huge satellite dishes back in the 70' and 80s.. little moter with a long bolt that spins a nut up and down a pipe.. a tiny motor can really move something like that
