DC 48V 500W ER11 Brushless Spindle Motor Driver Speed Controller For CNC Machine
A part of the review has been auto-translated.
good quality aluminium clamp which was a pleasure to weld. Works great on my 3020cnc.
Package arrived with all components in good health. I was surprised how heavy it was for such a small motor. Pros: It has just a little (very bearable) noise when running at about 13000 rpm. The driver works as it should and the speeds is adjustable with a potentiometer or software Cons: when lowering the RPM the power also drops somewhat. When setting the RPM to about 4000 rpm (or lower) with the potentiometer the motor starts to have some jitter. Constructive: The bolts for the clamp could have been be a little bit longer. (now about 8mm longer then the clamps) The switch has been connected wrong: the switch off setting turns it on. Will try this on my table CNC and see how good and strong it is. (possibly will add some extra review about this)
