[PSUBS-MAILIST] electric manipulator

 Alan,It is rock solid when it stops, with no creeping.  I think the load is so small that the motor coasts to a stop.  I will try a load on it and make a little video.Hank

 Hank,I haven't experienced any of my actuators doing that. I am talking about3 different types & 6 all together. I also have a person hoist with two actuatorson it & it is pretty solid! I have run them without controllers, justhooking them up to + & - terminals. Would have thought the gearing wouldbe enough to stop the motor dead once the power was off. Are yourunning it off the Lenco controller or just wiring it straight from the batterieswith a switch in between?Could it have anything to do with the ball bearing system? Have you gotsomething wrong in the reassembly? In it's application on a boat it should be rock solid for positioning the trim tab against a fare amount of force.Alan

Alan,Is there way to electronically stop the motor in my actuators?  My mitre saw has a brake, just wondering what thats all about.  I have two functions done on the new arm and the actuator coasts to a stop  witch makes it difficult to control.  The arm is not under load in these early tests.  Maybe when the arm is under load it will be better.  I could put a speed control on the power feed line and the actuators would still be powerful enough.  The actuator is a bit fast but as I said with no load.  I think I will do some weight lifting tests tomorrow.Hank
