stepper driver

Hello everyone, I read all sort of different things about setting the correct current to drive a stepper motor, so now I'm a bit confusioed. 1. The value for current that is usually given in specs is RMS? 2. To calucate the current to drive the motor we start from the RMS current? And what...

I’m creating a Kicad PCB design to replace a breadboard circuit I’ve built that helps drive three stepper motors controlled by an ESP32, TMC2208 controllers and a 4x4 keypad. The breadboard setup works well. I’m now on to designing the ground fill zone and reading tutorials etc I’m become...

Hi, I'm currently trying to get a 3.3V microcontroller (Freenove ESP32 WROOM) to work with a stepper motor controller that requires 5V control signals (DM542T) and I am trying to use Sparkfun's Bi-Directional Logic Level Converter which has a design based on 4 BSS138 N Channel mosfets. When I...

Hello everyone, I am using the Analog Devices TMC5240 to drive a Sanyo Denki Sanmotion SM2564C20B41P bipolar stepper motor specs 2A/phase, 2.1 Ω/phase & 11mH/phase. I will be powering the stepper with 24Vdc @ approx. 2A. The data sheet (attached) for the Analog Devices TMC5240 stepper driver...

Greetings! Stupid question. I'm using a stepper motor to drive a teeter-totter for a Halloween decoration. My wife wants it to start up on motion. The driver I have returns to "off" on re-energization, so I'm planning on leaving the driver on and set to speed and using a motion detector to...

Hi, This probably isn't super complicated but I have to control 3 stepper motors simultaneously with an esp32 for part of a robotic arm. These are the nema 23 stepper motors I am using, they are normal open loop 4 wire stepper motors. These are the motor drivers I am using. One pin tells...

In the datasheet of the TMC5130 (and that of other driver ICs), Trinamic recommends to use a low ESR filter capacitor of 100uF for filtering the power supply in order to cope with the current ripple caused by chopper operation. Can the capacity be scaled down (when space is limited) when using a...

Hi! After producing multiple different PCB designs of a board for controlling a stepper motor, I noticed something that I cannot explain. The boards are in general powered through 12 volts, then a voltage regulator brings the voltage from 12 to 5 V and another one from 5 to 3.3 V. Stepper...
