    I want to see real evidence that this setup can do serious work. Any positive comments from Chris should be read in conjunction with his initial enthusiasm for the defective setup.

    This issue of the total inability of the 'controller' to maintain some semblance of speed control under varying load is more than 8 months old.

    'sensored'. Is this a new word?.

    'Censored' is what this excuse for a motor control system should be.

    These motors have revolution feedback only, there is no way they have any timing sense.

    I disagree, this controller lacks PID control at any speed. This is what I posted last November. I am not aware of any change. Zhang did not answer my email request for an update.

    My Interact has a Kennametal QC collet holder spindle without a drawbar. I suppose they were all like this.

    An induction motor runs at a full load slip speed of about 3-5%, any further load and it will stall. A BLDC motor has no inherent speed or torque control, it is done by the controller. The Sangmutan...

    Interact 1 mk2 spindle motor
