ABSTRACT:
Electric motor with a system for speed monitoring, especially for ventilators, fans, blowers and compressors, where the speed is monitored with the help of a speed-proportional signal, consisting of a stator and a rotor which can rotate in the stator, where the system for speed monitoring consists of a permanent magnet (16) which is mounted in the front end (14) of the rotor (2) which faces the stator (3) and a detector (12) which can be triggered by the magnetic field of the permanent magnet and is located on a circle with its midpoint in the axis (4) of rotation of the rotor (2) and with a radius corresponding to the radius of the circular path of the permanent magnet (16).
