The minimum possible speed is zero. First you have to tell us what kind of stepper motor you are using two poles or four poles, the hardware is different and the program too. Tue Apr 27 , The program assumes a unipolar stepper motor. This helps because the jitter is not as great when the step period is long compared to the cycle time.

A half-stepping or micro-stepping controller would approximate the ideal sine waves more closely, but this is good enough.

Note that this introduces phase noise or, equivalently, jitter on the motion of the stepper motor. So there's three wires per winding, so this is a six-wire stepper. The minimum possible speed is zero. Amigo obrigado por responder eu utilizo um motor de 4 polos.

A rising edge on Xfaster increases the stepper speed by one unit, and a rising edge on Xslower decreases it by one unit. Xfaster and Xslower determine the speed, and could go to pushbuttons. This is a motor where each of the two windings is center-tapped. If you're ramping the motor to run faster than the pull-in speed i. Xforward and Xreverse determine the direction of the motion.

This helps because the jitter is not as great when the step period is long compared to the cycle time. In some cases, the manufacturer will tie the two center taps together, and call it a five-wire stepper; but that doesn't change anything for us.

Tue Apr 27 I wonder how to increase and reduce the speed of a stepper motor. Fomo stepper motor has two windings, spaced ninety degrees apart. Such a system is often called a "direct digital synthesizer", or a DDS, and they all generate phase noise in varying amounts. Every cycle, an accumulator is incremented by the speed. In fact, a typical stepper motor requires many steps to make a full revolution, so there is some integer scale factor between electrical and mechanical phase.

This is a quadrature sequence, or a 2-bit Gray code. Sat May 1 The program assumes a unipolar stepper motor.

Or they would be, if the stepper motor made one revolution per step. The same program could be used with bipolar no center tap on the windings motors; it would just be necessary to acelwrar those output signals drive whatever H-bridge you were using. Hello Marcio, will be difficult to find a response in Portuguese but if I can help Then by grounding the left side of the coil, we can make current flow one way, and by grounding the right side, we can make current flow the other way.

If both are false or both are true then the motor is stopped. The program accepts cmoo sets of inputs. O motor de passo foi um exemplo que utilizei. If the accumulator is greater than 20, then we take a step in the requested direction.

I chose arbitrarily to represent the maximum speed as 20, and the minimum as 0. See the attached example. We apply aceleerar positive voltage rail to the center taps of the coils.

First you have to tell us what kind of stepper motor you are using two poles or four poles, the hardware is different and the program too. Gostaria de saber como aumentar e reduzir a velocidade de um motor de passo.

    I apologise, but, in my opinion, you are mistaken. Write to me in PM, we will talk.
