i need big time help on this one please :!:
design a stepper motor controller using a simple digital circuit. it is supposed to activate the phases one by one in cyclic order. the speed of rotation(rev/sec)= no.of steps activated / sec * step angle/360
step angle=1.5 deg
stepper motor current/phase=80mA
design the circuit using johnson ring counter. design the transistor switches using BC557 to drive stepper motor phases.
how do i calculate frequency of the clock signal that will cause the motor to rotate at given speed.
