At least at times during the braking process, a brake current fed back on the basis of an electrical brake voltage induced by the drive motor is conducted to an ohmic heat resistance, namely by closing an electrical switch. A temperature of the drive motor is detected, and a threshold value for the temperature is set. The electrical switch is controlled during the braking process such that the temperature of the drive motor remains below the specified limit.
  • a current flow is thus controlled via the Ohms Wderstand during the braking process such that the temperature of the drive motor does not exceed a predetermined limit.
  • the control of the flow of current through the resistor or the control of the electrical switch preferably includes that the average current strength of the braking current and / or a time duration of the current flow and / or a time at which the electrical switch is closed during the braking process, depending on the determined temperature of the drive motor is / are set.
  • the limit value for the temperature of the drive motor can be set, for example, in a development process of the drive motor and stored in a control device.
  • the method according to the invention has the advantage that the drive motor can be braked rapidly by passing the braking current to the heat resistance without exceeding the limit value for the temperature.
  • the drive motor had to be designed for the most unfavorable operating conditions (worst case) in order to be able to withstand temperature peaks occurring during the braking process.
  • the drive motor had to be designed for the maximum ambient temperature of the washing machine, for maximum loading of the washing drum and for the longest washing program of the washing machine.
  • the method according to the invention makes it possible for the drive motor to be designed for operation at lower temperatures and thus produced more cost-effectively. Namely, the limit value for the temperature can be set so that the drive motor is operated at moderate temperatures and thus is not overheated.
  • the washing machine preferably has a belt drive, so that the laundry drum is driven by the drive motor via a belt.
  • the drive motor is subjected to little thermal load during deceleration, and it can be braked quickly at the predetermined limit for the temperature without being thermally overloaded.
  • the ohmic Wderstand is formed by a phase strand of a stator of the drive motor, so that the braking current is passed through the electrical switch back to the phase strand.
  • the electrical energy delivered by the drive motor during the braking process is converted directly into heat on the drive motor, so that it is unnecessary to use an additional braking resistor - as used in the object according to EP 1 512 785 A1 parallel to the DC link capacitor.
  • the drive motor also has a significantly higher heat capacity than a braking resistor and can thus absorb significantly more heat. It can thus be decelerated significantly faster.
  • the drive motor is a multi-phase permanent magnet excited motor, for example a permanent magnet synchronous motor or a brushless DC motor
  • the phase strands can be short-circuited in pairs or all at least temporarily during the braking process of the stator and the braking current can be passed to the phase strands. It is advantageous if electrical switches already present in an inverter or inverter are used to couple the phase strings together.

  • Predetermining the course of the rotational speed may be, for example, setting a mean deceleration and / or a time profile of the deceleration of the drive motor.
  • the delay of the drive motor can be predetermined at least for the beginning of the braking process depending on the determined temperature.
  • the course of the rotational speed can also be controlled continuously during the braking process as a function of the instantaneous temperature of the drive motor. For example, with a relatively fast rising temperature approaching the limit, the drive motor's speed would be significantly reduced. In contrast, the delay can be increased according to the situation at a relatively moderately rising temperature of the drive motor.
  • the continuous control of the course of the speed as a function of the instantaneous temperature of the drive motor has the advantage that it is continuously monitored during the braking process, whether the temperature of the drive motor is below the specified limit. By appropriate control of the electrical switch and an associated control of the braking current thus also the respective instantaneous temperature of the drive motor can be controlled.
  • the temperature of the drive motor for the braking operation is estimated and the electrical switch is driven depending on the estimated temperature.
  • a maximum value of the temperature for the braking process can be estimated before initiating the braking process.
  • time course of the rotational speed of the drive motor for the braking operation prior to its initiation depending on the estimated temperature in particular depending on the estimated maximum value, predetermined.
  • such a temperature of the drive motor can be determined before the initiation of the braking process, which could presumably occur during the braking process.
  • the time profile of the rotational speed or deceleration of the drive motor can be reliably predetermined even before the initiation of the braking process, without the specified limit value for the temperature is exceeded.
  • Temperature values for different courses of the rotational speed or different deceleration values for the braking operation can also be predicted and compared with one another before the braking process is initiated. Then, such a course of the rotational speed or such a course of the deceleration for the braking operation can be predetermined, which ensures a maximum possible deceleration of the drive motor without its temperature exceeding the specified limit.
  • Such an approach has the advantage that the drive motor on the one hand slowed down quickly and on the other hand is not thermally overloaded.
  • the electrical switch is controlled during the braking process such that, taking into account the limit value for the temperature, the drive motor is braked with a maximum possible delay. In this way, the duration of the braking operation is reduced to a minimum, without the limit value for the temperature of the drive motor is exceeded.
  • the braking operation can be carried out between two consecutive spin cycles of the drive motor. Then, a period of time between the spin cycles can be set as a function of the ascertaining temperature of the drive motor-determined in particular during the braking process.
  • the time period between the spin cycles is set in particular in such a way that the temperature of the drive motor does not exceed the limit value during the subsequent spin cycle or during a braking process subsequent to the later spin cycle. So the time is set so that after the previous spin the temperature of the drive motor can recover enough.
  • the drive motor can be accelerated to a predetermined spin speed, for example, and then decelerated again, without the Limit for the temperature is exceeded.
  • the duration between the spin cycles can also be longer than the actual braking operation, that is, the drive motor can first be braked to a desired speed - in particular completely to zero rpm - and the later spin cycle can be initiated only after the drive motor has been decelerated.
  • the temperature of the drive motor is determined before initiating the braking process-for example, at a spin speed of the drive motor-a time of initiation of the braking operation can be determined as a function of this temperature.
  • the duration of a spin cycle can be varied depending on the instantaneous temperature of the drive motor, namely such that the limit value for the temperature of the drive motor is not exceeded during either the spin cycle or during the braking process.
  • the braking operation can be initiated when the temperature of the drive motor in spin operation exceeds a threshold value smaller than the limit value. This threshold value can be selected such that a maximum temperature occurring during the braking process is less than the specified limit value.
  • the temperature of the drive motor can be measured with a sensor.
  • the temperature of the drive motor is determined by means of a control device, by which the electrical switch and the drive motor are controlled by means of a map stored in the control device and / or by means of a stored in the control device mathematical formula is calculated.
  • the washing machine thus comes without an additional temperature sensor.
  • the temperature of the drive motor may be dependent on its known parameters, such as a resistance of the stator winding or the resistance of the phase strand at a fixed temperature and / or a pole pair number.

  • the control device 39 takes into account the loading of the laundry drum 3 or the weight of the laundry items 4, as well as the instantaneous speed n of the drive motor 5. From this, the control device 39, namely the mechanical energy or the torque of the drive motor 5, from the mechanical Energy, the electrical energy and from the electrical energy, taking into account the Ohms Wderstands the phase strands 7, 8, 9 determines the temperature T of the drive motor 5.
  • the controller 39 controls the control device 39 in the braking operation of the drive motor 5, the electrical switches 31, 34, 37 at.
  • the controller 39 first charge the DC link capacitor 22 with the energy supplied by the drive motor 5.
  • the electrical switches 30, 33, 36 are activated, while the switches 31, 34, 37 remain open. If the DC link capacitor 22 charged, the switches 30, 33, 36 are opened and the switches 31, 34, 37 - as described above - driven.
  • the duty cycle of the control of the switches 31, 34, 37 and thus the course of the rotational speed n of the drive motor 5 can be continuously controlled during the respective braking operation, namely depending on the respective instantaneous temperature T of the drive motor 5.
  • Temperature T can be taken dependent on the situation that the temperature T does not exceed the threshold value T G.
  • the drive motor 5 is turned off; it is then waited that the temperature T falls below the threshold T G again. Then the drive motor 5 is put into operation again.
  • a separate braking resistor can be used in the circuit arrangement 6. Such a braking resistor can then be connected as needed depending on the DC link capacitor 22, namely via an electrical switch. Then the energy supplied by the drive motor 5 can first be stored in the DC link capacitor 22 and then converted into heat at the braking resistor. The electrical switch, via which the braking current I B is led to the separate braking resistor, is then activated according to the method described above, namely such that the temperature T of the drive motor 5 does not exceed the limit value T G.

Abstract

L'invention concerne un procédé pour commander un processus de freinage d'un moteur d'entraînement (5) qui entraîne un tambour à linge (3) d'un lave-linge (1). Pendant le processus de freinage, un courant de freinage IB renvoyé en raison d'une tension de freinage électrique induite par le moteur d'entraînement (5) est guidé au moins temporairement dans une résistance ohmique par fermeture d'un commutateur électrique (31, 34, 37). Une température T du moteur d'entraînement est déterminée et une valeur limite TG est définie pour la température T. Le commutateur électrique (31, 34, 37) est commandé pendant le processus de freinage de sorte que la température T du moteur d'entraînement (5) demeure inférieure à la valeur limite TG définie. La résistance ohmique vers laquelle est guidé le courant de freinage IB, est de préférence formée par une résistance ohmique d'un conducteur de phase (7, 8, 9) d'un stator du moteur d'entraînement (5). L'invention concerne également un dispositif d'entraînement (2) et un lave-linge (1).
