One word "Chopper" Nearly every commercial stepper motor driver I have ever seen uses a chopper circuit. This is because torque is related to current (actually its related to magnetic flux but that's related to current :-). The operation of a (...)

Francis, Thanks for the info! I'm not an expert, but doesn't PIC stand for "Peripheral Interface Controller"? Well, I guess it's all just semantics, they both could be correct... Just wondering, John Wynne (...) (26 years ago, 12-Apr-00, to lugnet.robotics.handyboard)

Is there an easy way to get more torque out of a stepper motor? Upping the voltage is not an option at this time. I've already decreased the width of the pulses enough (so that it has enough torque to start on its own without a push) that it goes (...) (26 years ago, 12-Apr-00, to lugnet.robotics.handyboard)

Dear Francois A du Toit: PIC stands for Programmable Integrated Circuit. Generally it is what we call a microcontroller. You write a program in Assembler, burn that program into the PICs EPROM or EEPROM. Then when you put the PIC in its circuit, it (...) (26 years ago, 12-Apr-00, to lugnet.robotics.handyboard)
