Electric treatment system

A treatment tool for performing a treatment for a curative procedure with ultrasonic waves, high frequency current and so on is provided with an identifier formed of a resistor or the like for indicating the type of the treatment tool. A medical instrument such as an ultrasonic wave output apparatus discriminates the type of a treatment tool connected thereto from the identifier to automatically set operating parameters such as an output value suitable for the treatment tool and to associatively operate an ancillary medical instrument such as a perfusion / aspiration apparatus depending on the treatment tool, thereby reducing extra work such as manual setting to allow for a smooth treatment.

Brushless, three phase motor drive

A control method for a sensor-less, brushless, three-phase DC motor. A pulse-width modulation (PWM) duty cycle may be calculated. A voltage induced by rotation of a rotor may be sampled at a first expected zero crossing value to produce a first sampled voltage value. An average of a plurality of sampled voltage values, including voltage values sampled at a plurality of prior expected zero crossing values and the first sampled voltage value, may be calculated. The first sampled voltage value may be subtracted from the calculated average to produce a delta zero crossing error. The delta zero crossing error may be multiplied by a first constant representing electromechanical properties of the motor to produce a representation of an angular velocity. One or more time values may be generated based on the representation of the angular velocity. Operation of the motor may be controlled based on the one or more time values and the PWM duty cycle.
