A single-motor surgical system for operating a set of different surgical devices having different operational limits, consisting of a handpiece containing the motor and adapted to alternately receive a proximal portion of each of the surgical devices, each device having an indicator on its proximal portion that denotes its operational limit, the handpiece including an automatic sensor for sensing the indicator, and controls responsive to the sensor to automatically establish the operational limit of the motor in accordance with the respective surgical device received by the handpiece. In preferred embodiments, the system includes an arthroscopic handpiece as above and has a plurality of surgical devices adapted to receive different removable rotary tips that have different operational limits of rotation, each of the plurality of devices having a vacuum passage connectible at one end to a vacuum passage of the respective rotary tip and adjacent the other end, to a vacuum passage associated with the handpiece, whereby tissue severed by the rotary tip can be removed from the surgical site, the surgical device indicating to the sensor the rotational limits of the tips which the devices are adapted to receive.
