Part Number: DRV8825 The figure below shows the VM current waveform when the motor stops. (Measurement condition: VM=24 V, Motor current: 1.7 A) DRV8825 is shown on the left and another company's product is shown on the right. In other companies' products…
Part Number: DRV8825 Hi support team.
My customer is having problems with the motor rotating.
When the motor is rotating at a constant rate, the current step changes suddenly. As a result, the HOME position will shift.
Even when I measure the rotational…
Part Number: DRV8825 Other Parts Discussed in Thread: DRV8462 , DRV8962 hi,
Questions:
1。How do different decay modes affect the accuracy of the stepper motor's moving distance?
2.Is there any detailed theory to explain that in fast Decay mode, the…
Part Number: DRV8825 I'm using the DRV8825 driver and having trouble with (unloaded) stepper motors 'stalling' at some speeds.
In this application I need the motor to spin at at max of 1000 RPM. I'm using a quadrature encoder knob and small…
Part Number: DRV8825 Other Parts Discussed in Thread: DRV8434 , Dear Team,
Our customer would like to estimate the thermal risk in their board.
As you know, Thermal information is in datasheet.
However, They don't know how to estimate the loss wattage…
Part Number: DRV8825 Dear all,
Based on the datasheet DRV 8825, the theory of calculating of maximum current limit is Vref / (5x Rsense)
If my Vref = 1V, then theoretically, my limit current shall be 2Apeak. Can I assume that I should be…
Part Number: DRV8825 I have a doubt for this IC, Its working good,but i connect my stepper with the kit the chip (DRV8825) starts heating up.
Please how to avoid this issue.

Part Number: DRV8825 Hello,
I need the meaning of the distortion of the current with the driver DRV8825.
The simplified schematic of my board is as follow:
0670-00.pdf
When I start the motor I see that the current is distorted. In these point (current…
