Electric food processor with a speed sensor for the motor shaft

摘要

A control and command device (50) for the motor (7) comprises measuring device (57) which measures the rotation speed of the rotary output shaft (23) in a contactless manner. The measuring device comprises a Hall effect sensor (58) fixed to the housing and an associated coding element (59) fixed to the motor shaft to influence the sensor. A controller controls the desired speed of the motor. The command element (51) connected to the controller controls the electrical supply to the motor according to the desired speed value and the measured speed value.
