Doublecheck Drivetrain Calcs

Unread postAuthor: VH_man » Fri Dec 04, 2009 10:40 pm

some of you may remember my Electric bike project.... Since that time I have learned such a wealth of knowledge it is unbelievable.

Well, I have decided to revisit it, Except this time I am making a 4 wheeled skateboard like device, using 4 inch Diameter Kick-scooter wheels as my drive wheels (although I might move to larger wheels)

Basically, I have an Excel spreadsheet I would like someone who knows their stuff to look over and tell me If I am doing things correctly. Right now, I am basing this drive-train on the "robotics" drive-train method, which is that the wheels will slip before the motor reaches the maximum allowable current. I am not including efficiency predictions, ect ect, I am simply "playing it safe", and leaving a relatively large buffer between my maximum allowable current.

My motor of Choice is a large FIRST CIM motor, which is about 300 watts and easily capable of providing the power necessary to move me. The specs on my Spreadsheet are for that motor.

Thanks in Advance.

That motor is slow start? It doesn't run max RPM from the start?
