Concept

 

The ROBA®-alphastop® is a safety brake, installed between the servo motor and a bell housing (see Figs. 1 and 2). The brake gear hub is combined with smartflex®, a backlash-free metal bellows coupling. Frictionally locked clamping rings ensure backlash-free torque transmission between motor and the ball screw spindle. Both sizes of the ROBA®-alphastop® are suitable for Fanuc servo motors, sizes 6 to 30, or for other motors with the same frame size. The brake is delivered with a connecting plug and a bushing. The standard coil voltages are 24 VDC and 90 VDC. Other voltages are available on request. The brake can easily be installed into pre-existing designs. Different coupling sizes and a special adaptor kit (see Fig. 1 centre and page 5)

help to fit the device to the varying shaft distances.

 

Design

Installation into pre-existing designs between the servo motor and the bell housing is simple and possible without alterations. However, altering the bell housing can optimize the length of the drive, and therefore, on vertical axes, the machine height
