Hi David,Hi everyone,
I have been given a couple of electric motors, an hydraulic pump and a contactor. This stuff is used on hydraulic tail lifts on trucks. I'm planning on using them on a kart for my ealdest kid and the bigger one on a motorcycle or moped(what ever possible). I do have some questions though as I am new to the the world of EV's.
1) Can somebody tell me what kind of motors these are (series/ PM or whatever...?) by looking at de specs?
Due to the fact that they have fixing screws at 90° around the middle of the frame, I'm guessing they are wound field motors, and almost certainly series motors.
Sure. But you run the risk of burning the comm and brushes and breaking mechanical stuff unless you have a current limiting speed controller. And on the other end of the acceleration sequence, the higher voltage may cause overspeed, especially if lightly loaded.2) Is it possible to up the voltage (ex. de 3 kw 24V to 48V)? If so what steps to take?
Yes.3) Both motors turn clockwise, if I cut the Hydraulic pump an inch or so, I can get both shafts to stick out en add a sprocket(cut one down to housing size of course), can I use the pump without the oil or do you think the shafts will eventually wear down?
edit...I mean you need oil.
They do look like nice little motors
