Abstract
Improvements introduced in a control circuit for a brushless dc motor with automatic start, which has a permanent magnet rotor and a stator winding, with a construction element that depends on the magnetic field and is exposed to the field of the motor. Rotor for picking up the position of the angle of rotation, and with an electronic controllable element that is connected in series with the winding of the stator to the direct current source, which regulates the passage of the flow through the stator winding depending on the position of the angle of rotation of the rotor, the parametric variation can be transformed as a function of the magnetic field of the construction element depending on the same magnetic field, in a control signal for the regulating element, characterized by the fact that the control circuit (19, 20, 24, 29, 34) has an oscillator (19) with an oscillation circuit lc, whose in ductivity is formed by the construction element that depends on the magnetic field executed as sensor coil (10) with core, because the oscillation of the oscillator (19) is modulated as a function of the induction caused by the rotor field in the sensor coil (10). ), because the control signal for the regulating element: (4) can be derived from the modulated oscillation of the oscillator, and because the frequency thereof is considerably higher than the rotational speed of the rotor.
