Although the motor is driven by DRV8818EVM, vibration and heat of a motor are large.
Although it seems that the elegance of the other company does not have most vibration, is this the feature of DRV88 series?
A customer's spec. is written to below.
---------------------------------
- 24VM/1.5A
- A motor is an oriental motor :P K243DA
* There is likely to be no mistake in connection.
- Ichop:1.5A
- Slow decay
- Full step
⇒1/8 step is used, vibration will decrease, but it remains.
- Even if it makes speed quick and makes it late, it vibrates.
(Vibration has little quicker one)
- Even if it makes current small, vibrate.
-A circuit uses DRV8818EVM as it is.
[DRV8818EVM specification]
- Start speed:128
- Target speed:200
- Sync Recirculation is check
- Accel rate:50
* Although he would like to set Ichop to 1.5A, Vref is then set to 1.7V.
Is it reasonable although the formula of a datasheet is differed from?

Thank you for your consideration.
