- How do I control a stepper motor with a 0-10Vdc input?
The stepper motor drives the valve in one direction from 0 - 100% open and then I will need to drive it 100 - 0% by reversing the direction In other words, if the input is 5vdc, it needs to drive the motor in the open direction for half of the time it takes to drive the valve 100% open which will be 50% open
- NEMA 17 Stepper motor torque output calculation - Adafruit Industries
Stepper motor torque is directly proportional to the steady state winding current, so if you double the steady state current, the torque will double With a current limiting driver like the one you are using, use an oscilloscope to characterize the current waveform and calculate an average, which should give similar results to the steady state
- Slip Ring with Flange mounting to stepper motor - Adafruit Industries
Can your slip rings be used to transmit stepper motor pulsed signals at 200 rpm without creating spikes noise that could cause precision performance problems? The data sheet says electric noise is smaller than 0 01Ω and the motor's phase coil are 0 9Ω, so i guess it should be ok

Re: 24V Stepper Motor Driver Post by BURevisfan » Sat Jan 01, 2022 9:32 pm I wish I could find a link to the specs, I’ve been very unsuccessful at finding any so far
- Controlling a Stepper motor for antenna tuner - adafruit industries
The Ardiuno and stepper driver board should also be in the shielded compartment I would also add a number of TVS to all lines connected to the Ardiuno to clamp any transients and RF Your first task is to determine how much torque is required from the stepper motor to turn the tuning cap
- MCP23017 with Stepper Motor? - adafruit industries
Hi, I'm trying to use an MCP23017 port expander to control a 28byj-48 stepper motor with a ULN2003 driver Right now, I'm just trying to get the one to work, but the eventual end goal is to connect three MCP23017s and use them to drive six stepper motors (each with their own driver board), in response to a sensor
- Stepper Motor Issues when Running at Lower Frequency
Im using the stepper motor class from the adafruit motor library using blinka to operate the library on the rpi (because its not a microcontroller) When running around 1000 hz, the motor runs smoothly and seems great, but at anything only a couple hundred hz less or more than that, it has a very strange behavior
- Reducing Stepper motor (acoustic) noise - adafruit industries
Stepper noise is mostly due to vibrations induced by the discrete steps This can excite vibrations in the structure that the motor is attached to Stepper vibration can be softened by using interleaved or microstep stepping modes It can also be damped with things like rubber washers on the motor mounts
