hi,all i have unipolar stepper motor with step angle 1.8 i use the following code to rotate it in full step mode (4 sequence)
mov a,#66h
mov dptr,#portc
mov r7,#4h
N91:mov r6,#29h
begin3:movx @dptr,a
rr a
acall delay2
djnz r6,begin3
djnz r7,N91
where delay2 represent delay=23.911ms how i can calculate the following parameters:
(i know resolution=360/1.8=200 step/revolution)
1.pulse frquency resolution
=1.8*f/360=?where f:stepping frquency(pulse rate)=?
2.motor speed?
3.number of pulses required to move shaft through 54 degree?
4.revolution/minute (rpm)?
5.steps/second(pulse/second)=(rpm*200)/60=?
how i can know number of phases and number of stator or rotor teeth if i have no data sheet i take the motor from dot matrix printer
thanks in advance for help,suggestion,guiding
