Help with motor control. Thread starter joshua17ss2 Start date Mar 8, I am wondering if anyone could shed some light on this.
I have an old F11 electric wheelchair, i was originally trying to modifiy the joystick that controlled the motor controller. F1010 will load pictures of the motor controller when i get on a high speed internet thanks.

HIB where you find the datasheet can datasheeg post a link. Sceadwian Banned Mar 9, Pictures would really be needed, I don’t see why you couldn’t tap into the existing motor controller as long as you’re sure it still works, it should be pretty simple, though I’m guessing you’ll need at least a basic external driver circuit from a PIC to drive it, if nothing else to adjust voltage levels.
When you take pictures f10100n sure you get good shots of all the IC’s on the board or label the picture somehow and type the chip numbers out in text with the post. Datasheer post a link to the PDF. I will try and post some pictures tomorrow, just gotta get to a high speed connection. The motor controller had a daughter board attached the ran everything, it accepted the serial commands and converted them in to the driving singals.
Why do you need to get to a high speed connection?

Open them in “paint” and save as jpg’s. Pictures of the motor controller top and bottom, i labeled the back view picture, you need to zoom to see the labels came out alittle smaller then i was thinking but there are very clear when zoomed. The 16 transistors, are FN, the 2 motor control chips are HIPIB, there f1010b a single transistor that serves as a 12 volt regulator.
I daatasheet hooked my rc reciever directly to the pwm lines for the motor controller but only registered a change of 1 or 2 volts datazheet my Multimeter. Mabye i connected the Reciever wrong, i grounded the grnd in to the ground shared by the rest of the circuit, and then i connected the signal line to the pwm input on the chip.
I will toss together a pic chip tonight and try feeding it a pwm signal from that see if i get any results. Are you using the same pwm for bolh BLl and ALl you have to invert one of them I drawled it out for you. Can anyone help me solve my problem? Sceadwian Banned Mar 14, r1010n Apparently your motor is not bidirectional.
Does it have a gear head on it? Some motors with built in gear datasheey aren’t reversable. You can do it with this http: Sceadwian Banned Mar 25, Use a logic inverter? You can make one easy but it takes 4 transistors to make what he needs.
