Unipolar stepper motor in proteus

[raul260291]

Can anybody post the sequence used to rotate the stepper motor in clockwise and anti clockwise rotation in proteus.

I am trying rotate a stepper motor using serial interface.
well when i am sending the sequence it is not rotating but when i ground one of the phase it is rotating without giving the sequence

the sequence is
01100110
00110011
10011001
11001100

for clockwise rotation
and

01100110
11001100
10011001
00110011

for anti clockwise rotation

what is the difference between full step, half step and wave drive

 

[alexan_e]

In full step two of the coils turn on in each step, this gives the highest torque, the rotor is positioned between the two active coils
In wave drive only one coil is active, the rotor is positioned on that coil
The half step is a compilation of the above, it alternates driving two coils and one coil

Hi alexan,
THanks for ur reply but mYstepper motor is rotating ROTATING VERY SLOWLY .
HOW TO INCREASE THE SPEED OF IT?

 

[alexan_e]

The rotating speed increases with the step sequence speed, if you apply faster steps then the motor will turn faster.
If you are already applying fast steps then maybe your motor is geared and is not supposed to be turning fast as you expect.
