The speed of the rotors rotation in a stepper motor may be controlled in a variety of ways. Three such possibilities are through a series resistance, gearbox and voltage regulation. Each type has advantages over each other, and a methods implementation depends on the motor application and functionality.
How do you change the speed of a stepper motor?
There are two ways you can control the speed of your stepper motor. You can either decrease the delay time between each step or you can adjust the size of the step the motor takes. Decreasing the delay time is straightforward, just lower the delayMicroseconds and the stepper motor will have an increased step rate.
Can you control a stepper motor?
Coding the Stepper Motor
In the case of stepper motors, we can easily control them with the stepper library and there is no need to code each step. The next step (which is optional but recommended), is to define the number of steps you want the motor to rotate in one complete revolution.
What limits the speed of a stepper motor?
A stepper motor’s low-speed torque varies directly with current. How quickly the torque falls off at higher speeds depends on a number of factors such as the winding inductance and drive circuitry including the drive voltage. Setting a velocity limit will prevent the stepper motor from stalling.
How do you control the rpm on a stepper motor?
A third method for stepper motor speed control is voltage regulation. By utilizing an LM555 timer, the current supplied will become a square wave. The “high” time of the signal will be when the rotor rotates. These three methods allow for the speed to be controlled in any number of applications.
How can a stepper motor be controlled without a library?

How fast can a NEMA 17 stepper motor go?
The Nema17 stepper motor is a stepper motor with an end face size of 1.7 inches x 1.7 inches. Available in single and dual shaft, 1.8° step angle and 0.9° step angle, round and cut shafts, and can be customized. The driving voltage is 12-24V. The maximum speed can be as high as 2000 rpm.
What is a stepper motor controller?
This pattern is what energizes the phases, in the proper order, to drive the motor one step at a time in one direction or the other. A schematic of a simple stepper motor driver. Source: electronics-diy.com.
Does microstepping reduce speed?
Microstepping has two principal benefits: it provides increased resolution without a sacrifice in top speed, and it provides smoother low speed motion. … A shaft speed of 40 revolutions per second results in a linear velocity of only 40 mm per second.
