Definitions

  • the invention relates to a circuit arrangement for operating a brushless single-phase motor, in particular a hysteresis motor, on the DC network of motor vehicles of the type defined in the preamble of claim 1.
  • Hysteresis motors offer the advantage of asynchronous starting with a relatively high starting torque and synchronous running after self-synchronization with a torque, the maximum of which is determined by the hysteresis torque.
  • the two amplifiers are controlled by a resonant circuit with a constant frequency. If the DC voltage of the motor vehicle electrical system drops below a lower value in this circuit arrangement, the motor can no longer start because the motor current decreases as a result of the AC resistance. If, on the other hand, the line voltage rises above an upper value, the motor current increases inadmissibly.
  • the permissible voltage range between the upper and lower value is relatively small, so that in the case of the voltage fluctuations usually occurring in motor vehicle electrical systems, which can be between 6 V and 16 V, circuitry-intensive measures would have to be provided in order to ensure the correct operation of the hysteresis motor
  • circuit arrangement according to the invention with the characterizing features of claim 1 has the advantage that the motor start-up is reliably ensured even at the lower end of the fluctuation range of the DC network voltage of vehicle electrical systems. The speed is automatically limited at high mains voltages.
  • Push-pull operational amplifier designed, while in a unipolar motor winding with center tap and with only one permissible current direction in each winding branch, the two amplifiers according to the embodiment of the invention according to claim 5 are advantageously designed as simple power transistors.
  • a hysteresis motor operated with the circuit arrangement according to the invention is particularly suitable as a drive motor for a temperature sensor fan of regulated air conditioning systems in motor vehicles.
  • the temperature sensor of the air conditioning system is constantly ventilated with indoor air, which by means of this
  • the drawing shows a block diagram of a circuit arrangement for operating a hysteresis motor on the electrical system of a motor vehicle.
  • the hysteresis motor designated 10 in the drawing and shown only schematically, is known in its structure and mode of operation. In general, its rotor contains an annular sheet with high specific hysteresis losses.
  • the excitation or motor winding is housed in the stator. It can be bipolar or unipolar. With a bipolar motor winding, this is alternately in the opposite direction from
  • a center tap is provided, and the two winding branches formed by the center tap are always alternately flowed through by the motor current in the same direction.
  • the two ends of the motor winding are each connected to the outputs of two amplifiers 11, 12, which are designed as push-pull operational amplifiers or simple full-bridge branches in the case of the bipolar motor winding and as simple semiconductor switches, for example transistors, in the case of the unipolar motor winding.
  • the two amplifiers 11, 12 are operated in push-pull mode, so that the motor winding is alternately connected via the amplifier 11 or the amplifier 12 to the DC voltage of a motor vehicle electrical system 13.
  • the control inputs of the amplifiers 11, 12 are each connected to one of two outputs x, x of a voltage-controlled oscillator (VCO) 14.
  • VCO voltage-controlled oscillator
  • the VCO 14 delivers a control pulse sequence at the output x, the pulse repetition frequency of which is proportional to the voltage at its control input. The same pulse sequence is present at output x, but is shifted by 180 ° with respect to the pulse sequence at output x.
  • the control input of the VCO 14 is connected to the electrical system 13 of the motor vehicle via a diode network 15.
  • the diode network 15 contains at least one zener diode 16, which specifies a lower threshold voltage for driving the VCO 14. With a second Zener diode in series with the first, the maximum control voltage reaching the control input of the VCO 14 and thus the maximum frequency can be determined.
  • the hysteresis motor 10 behaves between the threshold values predetermined by the diode network 15 similarly to a conventional DC motor, i.e. the engine speed changes analogously to the applied voltage.
  • the start of the motor 10 is also ensured in the case of on-board electrical system voltages that are in the lower region of the Vehicle electrical system fluctuations, e.g. 6 V.
  • the frequency is limited so that the hysteresis motor still starts safely there.
  • the invention is not limited to the exemplary embodiment described.
  • a VCO with only one output can be used.
  • Push-pull operation of the amplifiers can then be effected by connecting the output of the VCO to the inverting input of one and to the non-inverting input of the other amplifier or by connecting the output of one to the input of the other amplifier.

Abstract

Dans un circuit pour actionner un petit moteur monophasé sans balai, notamment un moteur à hystérésis, dans le réseau à tension continue de véhicules automobiles, pourvu de deux amplificateurs (11, 12) travaillant en symétrie et dont les sorties sont reliées à l'enroulement du moteur, les amplificateurs (11, 12) reçoivent une fréquence de commande proportionnelle à la tension d'alimentation de bord afin de garantir un démarrage fiable et une limitation de la vitesse de rotation du moteur sur toute la plage de fluctuations de la tension d'alimentation de bord. Cette fréquence de commande est prélevée par un oscillateur commandé en tension (14) dont l'entrée de commande est reliée au réseau de bord (13) par l'intermédiaire d'un réseau de diodes (15).
