I tested the current consumption and here is what I found, there is between 0.2A and 0.35A of current consumed when in motion but the consumption interestingly jumps to 0.520A when at still. In general, more torque is correlated with more current. The drive mode and speed together determine the torque.

If your driver does this, then it's possible for speed to have an effect.įor stepper motors, the speed doesn't determine the current use, but rather, the drive mode does. I have no idea why they'd do that, and mine certainly doesn't (it's just an L293D that I control will a shift register), but I'm just covering my butt here.

Now, it's possible that some motor drivers will switch off all phases in between steps, regardless of drive mode. If you are programming your own logic, you can actually control this - which might help prevent overheating. The current it will draw in a holding state depends on at what stage of the drive mode the motor was held. So in half-step mode, you can expect this motor to draw 530mA at 12V on average. Half-step mode uses a bit less current, because half of the time, only one phase is one. Even when it's not moving and just in a "holding" state. In two-phase on, full-step mode (probably the most common mode), both phases are always energized regardless of speed, and at 12V, this motor draws 353mA per phase - 706mA in total - constantly. Whether one or two phases are energized and how often is based on the drive mode. When only one is energized, the motor draws 353mA. At 12V, when both coils are energized simultaneously, the motor draws 706mA. Each phase is essentially a completely separate electromagnet with 34 ohms of resistance. Stepper motors draw a fairly constant current when the coils are energized, regardless of speed. For motors, current consumption generally goes up linearly with an increase in speed, but I don't know what speed the rated current corresponds to, or if it's just an indication of the resistance of the driving coil. I'm not sure of the answer to your second question.

No extra current-dividing circuitry is necessary. As long as everything you have connected isn't drawing more than 1.5A total, your system will work fine. So you can connect your power supply to all your motors and other circuitry in parallel, and each one will only draw the power it requires at the speed/load you're running it at. 12V, but its current output will be 0A since there's nothing to draw any current.Īnything you connect to the supply that does draw current will basically use only what it needs. Without anything connected to the supply, its voltage output will be e.g. A power supply is rated by it's voltage output (which stays constant), and a maximum current capacity. Thanks to Ohm's law, current (very helpfully) doesn't work that way. If somebody knows more details about this system combination: stepper motor (ROB-09238) to easy drive (ROB-10267) or have some comments on what I wrote please let me know. I had to use the sleep mode to turn the voltage off from the motor. I would say the 330 mA rated is per phase. It gets very hot unless it is hooked to some kind of heat dissipation thing. I think that is what is going on the easydrive chip can take that current but it needs an aluminum on top to dissipate heat. Now, 12V/36 aprox 334 mA times 2 aprox 670 mA. times two I was able to read aprox 280 mA total from my power supply.

I was able to see that always both set of coil are energized when pulses are not going in the easy drive.

I was able to see how the signals change per set of coils when I send pulses from my Signal generator from low and high frequency (couple of HZ to 10Khz). I connected 2 LED back to back with 1K resistor each as one set of coils and another set of LEDs for the second set of coils. I did check the cables and I saw the pulses on my scope. Power via the power supply of the C-885.AgustinGS thank you for your answer. Can be expanded with optional digital inputs and outputs.
