    • In a method for the detection of the rotational position of the rotor of a DC motor with commutator by evaluating the time development of a rotor current signal of the DC motor, said signal comprising a periodic waviness around an average value and comprising current ripples generated by commutation which are superimposed to said waviness, the rotor current signal of a current ripple detector unit (30) is supplied for detecting the current ripples of the rotor current signal. The rotor current signal is further supplied to a waviness detector unit (34) for detecting a half or full wave of the rotor current signal. The current ripple detector unit (30) is arranged to output a current ripple pulse for each detected current ripple. The waviness detector unit (34) is arranged to output a waviness pulse for each period of the waviness. The output signals of both detector units (30,34) are supplied to a logic OR unit (38) for generating a logic signal. Within a period of the rotor current signal, at least one of the detector units (30,34) will output a pulse. Thereby, the logic signal comprises a logic pulse for each period of the rotor current signal.

    • A control circuit is proposed, which can be used for the phase-shift control of an electric motor in an a.c. voltage supply line. The ground connector of the control circuit, together with the cathode of a semiconductor switch (triac), is directly connected with load current circuit. Because of this, it is possible to do without potential-separating means when it is intended to feed signals at the load current circuit directly into the control circuit. An auxiliary voltage source is connected between the synchronization input and the ground connector to maintain the function of the synchronization input.

    • A magnetic tachometer sensor for a motor control circuit having a motor driven interrupter wheel in proximity thereto supplies a motor speed signal to a frequency to voltage converter. The frequency to voltage converter produces a DC signal proportional to the speed of the interrupter wheel. The DC signal is compared to a user selected reference voltage in an error amplifier, thereby producing an error signal. The error signal is supplied to an output comparator which also receives a sawtooth timing reference signal in synchronism with power supply alternating current. The output comparator switches to trigger a triac into conduction when the sawtooth signal voltage exceeds the error voltage, thereby providing highly accurate timing of the switching point of the triac. The triac is arranged to provide a phase angle speed control for an electric motor used in a household appliance.
