Re: JVN-Design Calc Question
Use the pitch diameter of the sprocket you're driving with your motor as your pulley diameter.
If you're driving the 15t sprocket with your motor, use 1.79"
If you're driving the 44t sprocket with your motor, use 5.257"
Note: Current estimates in JVN's calculator don't seem to take efficiency of the gearing into account. So for elevators that experience significant amounts of friction or binding, your current draw may be above what JVN estimates.
