Nice 390 dc motor, the size fits right. The prototype test has passed, with the mass production of the product next, we will be buying more.

I bought it as a high torque dc motor for my own simple milling machine, mainly for processing plastics. Also, since it works normally even at 12V or less, it moves comfortably even at 20000 rpm or less. Nothing else to say fast delivery and too good and powerful I am satisfied with this engine thank you!
