Breadboard view of an SDSPIN220 stepper motor driver on a breadboard, powered by 3.3V from an Arduino Nano 33 IoT. It would be good to see a diagram of exactly what you measured between what wires. Brush A against ground briefly. Thank you for hosting this awesome site. Then brush C against ground briefly. Finally, they are mechanically secured with plastic cable ties. Can you help me to test it? For this experiment, we need a multimeter (a device for measuring electrical resistance). This is a 4-pole unipolar motor. If the problem seems to be electrical, use an ohmmeter to check resistance value. The stepper motor is a DC motor that can be stepped by a microcontroller.

Check Affiliate Disclosure, By By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. So, we need to keep the multimeter function in DC voltage. Learn more about Stack Overflow the company, and our products. Get a cheap voltmeter. Did this satellite streak past the Hubble Space Telescope so close that it was out of focus? When checking the ohms of other stepper rotators, it is essential not to mix up cables. you can run your stepper motor by adding only one capacitor! Can archive.org's Wayback Machine ignore some query terms? Learn more about Stack Overflow the company, and our products. (2) If there is resistance measurable between windings provide a resistance map. The motor should snap to a fixed position and it will be hard to turn it away from that position. We don't want that. If you do not know the voltage set the meter to the auto range function or to the highest range and work your way down. By using our site, you agree to our. Now proceed and attach the red probe to the green wire, and then close the switch by attaching the yellow wire to the black probe. As shown below, the indicated terminal matrix ( blue lines) shows the way the windings of a 3 phase motor should be tested with an Ohmmeter: The first thing to do before testing the windings of the motor is to remove the links linking terminals W2U2V2 and the disconnect the motor from supply (L1, L2, L3). Check that the brush springs still have enough tension to hold them securely to the commutator. Electrical Engineering Stack Exchange is a question and answer site for electronics and electrical engineering professionals, students, and enthusiasts. To answer this question, let's take a closer look at what a dc motor is actually. A Pocket Sundial From a Broken Pocket Watch! A multimeter is similar to an ohmmeter, and either of them will work for this test. To measure the resistance, disconnect the motor at the connectors (see Figure 1). 2H-422 STEPPER MOTOR DRIVER. Method 1 Checking the Motor with a Multimeter 1 Set your multimeter to a DCV setting. The voltage should be at least 12 volts. Next, Attach one end of your probes to each coil by placing it into their respective colored ports on top (green for Red Probe; yellow becomes black). Or, check the capacitor electrically with an ohmmeter. Hi my name is Rakesh Mondal , my friends call me ron vist my website for more stuffs like my post h. Share it with us! The multimeter will not beep in this case because you are using a different combination of wires for each coil, which can produce a reading if they were both attached at one point on their respective sensors (like when fishing). BUT it is more likely that you are using a voltage that is far too small. I rarely vote for anything involving 3D printing but seeing your sketches for circuits was kinda nice. Ground A and B. When the wires are twisted together, the larger the motor is, the greater the force required to rotate it. To test the wires that are part of the same coil, attach the red wire from the stepper rotator to the red probe. If you do this correctly, the multimeter will not beep or register any readings; your stepper needs fixing. You should only get ohms readings across two consecutive pins when taking your probe and attaching it to the third or fourth pin. Making sure to take note of any differences in resistance between each stepper rotator, you may proceed and verify the ohms values. This is the process for Circuit Tester A. I placed the input capacitors together with the linear regulator and heatsink on the left side. What is the correct way to screw wall and ceiling drywalls? Now turn on switch 3. Easy Identify leads on a 4 wire stepper motor with MultimeterStepper motors comes with different winding configurations. (R an arbitrary value) Can I tell police to wait and call a lawyer when served with a search warrant? It is annoying to spend much time and give a complete answer and then have do something else instead but SAY that they did what was asked. But what frequency to choose? If the motor hums but the belt doesn't move, the motor control board is the problem. Set a Digital Volt Ohm Meter (DVOM) to the ohm setting and test the motor while the power is shut off. My electric chainsaw motor still runs, but sparks and heat are coming from the brushes and commutator. Difference Between a Voltmeter and a Multimeter, What Does Negative Voltage Mean on a Multimeter, How to Test Cell Phone Battery with Multimeter, How to Identify Neutral Wire with a Multimeter, How to Test Air Fuel Ratio Sensor with Multimeter, How to Test a TP Sensor with a Multimeter, How to Test Dishwasher Circulation Pump with Multimeter, How to Test a Halogen Bulb with a Multimeter, How to Test a Subwoofer with a Multimeter, How to Test 30 Amp RV Outlet with Multimeter, How to Check Wiring Harness with Multimeter, How to Test a Headlight Bulb with a Multimeter, How to Test Solar Panels with a Multimeter, What is the Meaning of the Multimeter Ampere Symbol, How to Test a Stepper Motor with a Multimeter. All tester functions work as required. Good answer if you are ok with it moving very very slow. I have divided the circuitry into four parts and started testing it on a breadboard. The stepper has 2 or 3 coils. Were committed to providing the world with free how-to resources, and even $1 helps us in our mission.
