Also, rather than let the tail wag the dog, lets start with some actual objective requirements. 1) what is the mass of the load 2) what is the friction of the load 3) how quickly does the gate need to open? ie 1 second, 3 seconds, 5 seconds 10 seconds?? 4) can you determine the end stops BEFORE they are hit (ie limit sensors or a hard crash landing for the gate) what are the "end stops" of the load like, ie (hard, or soft) 5) How often does the gate need to be opened in any given time period (worst case) Then, calculate the starting force required (which is effectively your stall torque of your driving system) allowing perhaps 50 to 100% over range to cope with "sticky" gates due to wear or a lack of maintenance etc calculate the peak power for the driver (force x velocity) and the average power during the opening, and then calculate the average power during worst case useage (ie opening as often as is likely) Once you've done all that, none of which is difficult to do, THEN look at what the best way of driving the gate actually is....... :box: |
