5-motor walker circuit
The P5 design uses only eight 74HC/AC240 chips which are all octal inverting buffers. Each 74HC/AC240 chip has two groups of four inverters each controlled by a tri-state enable pin (pin 1 and 19). The 74AC240 chips (U1-U5) are used as H-bridge style motor drivers since they have almost double the drive current compared to 74HC240 chips. These mot
Controlling Motor Starting
Motor starters generally fall into two categories: full-voltage or reduced-voltage. The choice of which type of starter to use depends on various factors, such as current-carrying capacity of plant wiring, ability of plant power supplies to absorb power transients, size of the motor, and other special control requirements. The first type to be...
Unipolar Stepper Motor Control Circuit
This circuit controls a small, four-phase, five-wire, unipolar stepper motor, commonly designated the "KP4M4-001. " This type of motor was used in many 5 1/4" floppy disk drives in older computers. Now obsolete, such disk drives are often available on the surplus market for a small fraction of the motor`s original cost. The stepper motors are easy
When trying to move things with microcontrollers, there are basically three kinds of motors that are most useful: DC motors, servomotors, and stepper motors. Most all motors work on the electrical principle of induction. When you put electric current through a wire, it generates a magnetic field around the wire. By placing a charged coil of wire...
