Are there stepper motors with a wide RPM range?

Question

Are there such stepper motors, at a relatively affordable price, of a small size that are capable of having a minimum speed of 40 per minute and a maximum of up to 1000+ per minute? To work with Arduino. If so, can you give an example of several models?

Answer 1

It is correct to make up the way it is in the layout, especially if the site is not adaptive.
The fact that the customer saw the light already when the layout is ready is the customer's problem. Get paid for the work done, and then discuss a new task to finalize the layout and evaluate it according to the requirements of this very customer.
What these improvements will be and how real they are in general - it is impossible to say with the available data.

Answer 2

In the layout, in theory, the font is indicated not for 1920, but for the central block 1170. What's the difference, let your laptop be 1300, but this will not reduce the central block. In short, if reducing the font does not entail additional labor - just do it for free)) And for devices - use percentages, or rather, just look at how it's done, for example, in getskeleton.com

Answer 3

The speed of the motors is limited only by the fact that the magnetic field in the winding cannot change instantly. The effect is called the Hysteresis Loop .
Some materials have less hysteresis and high magnetic conductivity, but they are more expensive.
It is better to choose something in between and not chase the maximum.

Answer 4

Try the AccelStepper.h
library The fact is that the engine cannot immediately start at maximum speed, it needs to be accelerated..

Answer 5

To work in a wide range of revolutions, without loss of torque, as a replacement for stepper motors, servo motors can be used. This is a combination of a motor (dc, bldc) and an encoder, and sometimes a gearbox, due to which position feedback is built.
Usually, this is quite expensive if you need a resolution comparable to stepper motors. =)
In general, most small steppers up to 1000 rpm still accelerate normally, and if you don’t need a big torque, then you can make a step-up gearbox to get into the range.

Answer 6

This is in principle an achievable speed for steppers, with proper use, you can take any.
However, it should be understood that in addition to the stepper, the driver used, the motor supply voltage, as well as the motor control algorithm itself, matter.
