With sending one pulse into a motor, does that make it move a step?

Does changing the amplitude or width of these pulses do anything?

I'm trying to figure out how to increase a motors speed!

Thanks in advance!

A single short voltage pulse, applied to a DC motor, will cause it to advance slightly.

The area of the pulse is voltage * time which does not represent power, except in a resistor.
A motor is partly inductive so the current pulse will lag the voltage pulse. The power applied to the motor is the integral of (the instantaneous voltage multiplied by the instantaneous current).

Changing pulse amplitude or width will change the power delivered. But because of the inductive lag there will not be a simple relationship between amplitude, width and motor advance.

If you mean a stepper motor and controller it's based on pulse speed and the number of pulses.

you didn't specify what type of motor, stepper, DC or AC. Stepper is a set of pulses with pulse patterns for the next step. DC is a similar process. AC motors speed can be increased with the use of a Variable speed drive. VFD, this type utilizes pulse width modulation which is a simulated AC current via digital pulses. Then amplitude and timing of the PWM signals can then be used to control the rotations of the AC motor.

edit: just noticed the title specifying step

check the specifications on your particular motor, however it will have similar patterns as per this article

I can provide some insight into the concept of pulse control in motors. Sending one pulse into a motor will not necessarily make it move a step. The motor's movement is dependent on various factors such as the type of motor, its design, and the amount of force required to move the load attached to it. One pulse may not provide enough force to overcome the load and initiate movement.

However, changing the amplitude or width of the pulses can have an impact on the motor's speed. The amplitude of the pulse refers to the strength or intensity of the signal, while the width refers to the duration of the pulse. By adjusting these parameters, you can control the amount of force and the duration of the force being applied to the motor, which can affect its speed.

To increase a motor's speed, you may need to adjust the pulse parameters to provide enough force to overcome the load. It is also important to consider other factors such as the motor's voltage, current, and torque capabilities.

I would recommend conducting further research and experimentation to determine the most effective pulse control for your specific motor and desired speed. There may also be other methods, such as using a motor controller or changing the gear ratio, that can help increase the motor's speed. I hope this information helps in your quest to increase the motor's speed.
