cheers Hero999, im glad i didnt just start making this one up, frying a ton of hall's. i have very limited knowledge of electronics, the control system im using at the mo is a 6v suppy hall effect and power pnp transistor set up which woks fine.
I need to up scale the whole motor as i want to use it to drive my bicycle. a normal pulse motor is great but no real usable torque, the design i have uses 3 air coils pushing against 3 N52 neo magnets. even with 6v through the coils i am getting enough torque to get movment, but not much. i did try a reed switch set up and with 36v the torque is massive and the motor has no problem pushing me along a about 15mph.
I just dont want to use reed switches anymore. i am lost on the liner reg you mentioned and would have to spend a ton of time getting my head round it...is there any other way i can pulse the coils at 36v and still have a hall's + transistor / MOSFET system. a basic circuit would be good. I did think of having the hall powered by a seperate 6v supply with just the out going to the gate of the MOSFET, i just need to get the MOSFET to switch and allow the 36v to flow through the coil?????
any help would be good, cheers all
