Removing Electromagnetic Brake

Asking for compatibility between motor brake and variable frequency drive I got some conflicting answers. The manufacturer mailed the motor was designed to work but its retailer said it needed to be replaced. Facing that tricky situation I made the decision of taking the motor to pieces then photographed each part asking for help on the internet. The underlying thought was I just would have to reassemble if I didn't find out the right way about brake.

Of course I was aware that making such modification would lead to lose the CEE approval of the machine and that another user wouldn't be able to see the modifications from outside. My only reasonable possibility was to apply reversible removals as well as stapling an appended description to the technical manual. Eventually disabling the brake just needed to take off three pieces that I could quickly put back. In fact the tricky part was to take care of the ball bearings.

Some times later I knew I didn't have to remove that electromagnetic brake. The deceleration parameter of the variable frequency drive had just to be disabled, leaving the brake act by itself. Nevertheless I don't regret anything because the brake control of the variable frequency drive is far better (frictionless) than the hardware without lacking about safety. Actually the variable frequency drive controls the motor brake even if the supply power breaks. I experienced that amazing function more than once over the past years. However replacing origin brake needs some previous checks about safety as described in this document.
