摘要： A drive apparatus for a washing machine includes an electric motor, a drive shaft connected to the electric motor for rotary drive, a fan for cooling the electric motor and electronics for controlling operation of the electric motor. In order to achieve a compact construction, the electric motor and the electronics are integrated in a common unit, such as a motor housing. In order to protect the electronics and at the same time ensure that the electronics are sufficiently cooled, the common unit has a dividing wall, with the electric motor and a printed circuit board of the electronics disposed on opposite sides of the dividing wall. The dividing wall has at least one aperture. The electronics include power components protruding at least partially through the aperture and being in contact with the dividing wall and/or with a cooling air stream generated by the fan.

摘要： A method is specified for controlling a polyphase brushless electric motor, wherein the motor phase currents which are associated with the phases are produced by clocked variation of the respectively applied electrical potential. In this case, the motor phase currents flow back from the electric motor via a common return line with the peak current value in the return line being detected and being included in a controlled variable. Furthermore, a circuit configuration is specified, which is provided in a corresponding manner in order to carry out the control method. The control method and the circuit configuration allow the motor phase currents to be taken into account in the control of the electric motor in a simple and cost-effective manner.

摘要： An internal unit of a washing machine or spin-dryer normally includes a washing container, which has a laundry drum mounted in the container such that it can rotate, and an electric motor for driving the laundry drum via a reduction gear, a transmission, or direct drive. The internal unit is suspended in a machine housing such that it can vibrate and constitutes an overall system which can vibrate in a damped manner and which is subject to unbalance-dependent resonance phenomena in specific regions of the rotational speed of the laundry drum. The causes of these resonance phenomena are vibratory movements due to momentary unbalances in the load in the laundry drum. To reduce these unbalance-dependent resonance phenomena, the internal unit is provided with a vibration sensor which is rigidly or substantially rigidly coupled to the internal unit.

摘要： A method is specified for controlling a multiphase motor that is commutated by an inverter-side bridge circuit, in the course of which a particularly precise and technically simple detection of a control-relevant variable of a considered motor phase, in particular of a motor phase current and/or a back EMF voltage and/or a variable derived therefrom, takes place. It is provided here to determine the control-relevant variable with the aid of the current state of a freewheeling diode that is disposed in a phase half bridge, assigned to the respective motor phase, of the bridge circuit, the current state being detected during an on time in which a power switch, connected in parallel with the freewheeling diode, of the phase half bridge exhibits a conducting state, and a power switch connected in series with the freewheeling diode exhibits a blocking state.

摘要： A method for operating an electric motor with at least two motor terminals that are driven by a control device contains the steps of short-circuiting of at least two of the motor terminals of the electric motor by the control device; measurement of the motor phase currents at the short-circuited motor terminals; and identification of a standstill of the electric motor if a magnitude and/or a frequency of the motor phase currents measured lies below a predefined limit value. In the case of such a reliable identification of the standstill of the electric motor, an enable signal can then advantageously be generated in order, by way of example, to enable access to an apparatus driven by the electric motor.

摘要： Before a washing machine is switched over to a very high spin speed in the spin program of the washing machine, the existing imbalance due to irregular distribution of laundry in the drum should be checked. If the imbalance is too strong, the spin program should be interrupted if there is a threat of excessively high bearing forces to be expected. The fluctuation in rotary speed, which may have a high frequency due to the drum speed, and of the power consumption of the washing machine motor measured downstream of the direct current intermediate circuit prior to the feed thereof into the inverter for producing the rotary field in the motor. There, the vector product of the current and the voltage for imbalance measurement by determining power is blocked off from mains network interference effects by the high capacitance of the direct current intermediate circuit.

摘要： A circuit configuration for driving an electric motor, in particular of a washing machine, includes power switches connected to connection terminals of the electric motor and to a voltage intermediate circuit. A driver circuit is connected to the voltage intermediate circuit and to the power switches. A control unit, in particular a micro controller, is connected to the driver circuit. The control unit generates control signals for controlling at least one rotation speed of the electric motor. The driver circuit generates short-circuit control signals for driving the power switches, which bring about a short circuit of the connection terminals connected to the power switches, independently of the control signals from the control unit. The driver circuit generates the short-circuit control signals as a function of a detection of an overvoltage of the voltage intermediate circuit over a desired voltage range. A method for controlling an electric motor is also provided.
