Abstract
A surgical tool system including a handpiece with a power generating unit and a control console for supplying energization signals to the power generating unit. Based on the data in a memory associated with the handpiece, the control console supplies energization signals to the handpiece power generating unit in either a motor drive mode or a direct drive mode. In the motor drive mode the signals are supplied to windings integral with the power generating unit based on the position of a rotor also part of the power generating unit. In the direct drive mode, energizaiton signals are supplied to the power generating unit independent of rotor position.
