摘要： The present application is concerned with a motor unit having a motor having a stator and an armature, the armature being arranged for relative driven motion with respect to the stator, and a motor control unit having a supply circuit for providing a supply voltage at the motor to provide a set power level to the motor for driving the armature into motion, and a measurement circuit for measuring a value of a physical variable that is indicative of a current flow through the motor, wherein the motor control unit is arranged to interrupt the provision of the supply voltage by the supply circuit and to dynamically brake the motor during a braking time interval and further to measure the value of the physical variable during the braking time interval, wherein the motor control unit is further arranged to compare the measured value of the physical variable with a target value, which target value depends on the supplied power level and on an intended motion amplitude of the armature, to determine a new set power level in dependence on the comparison result and to subsequently provide the new set power level to the motor.

摘要： The invention relates to a method for controlling an oscillating electric motor of a small electrical appliance, according to which electricity is at least temporarily fed to a coil (5) in order to create a magnetic field that originates from a first motor component (1) and acts on a second motor component (2) such that the second motor component (2) is moved in an oscillating manner relative to the first motor component (1). At least one electrical parameter of the coil (5), which correlates with a movement-related parameter of the first or second motor component (1, 2), is determined for a moment in time during which electricity is fed to the coil (5). Electricity is henceforth supplied to the coil (5) according to the determined parameter.

摘要： The invention relates to a circuit arrangement for controlling an oscillating electric motor (1) of an electric small-scale unit which is operated by means of a voltage source (4) embodied as an accumulator or a battery. Said circuit arrangement comprises four switching elements (7, 8, 9, 10) which respectively authorise a current conduction, in a switched on state, and block the current conduction in a switched off state. Said switching elements (7, 8, 9, 10) are arranged in a full bridge circuit, according to which each switching element (7, 8, 9, 10) is connected between a first pole (5) of the voltage source (4) and a first connection (2) of the electric motor (1), between the first pole (5) of the voltage source (4) and a second connection (3) of the electric motor (1), between a second pole (6) of the voltage source (4) and the first connection (2) of the electric motor (1), and between the second pole (6) of the voltage source (4) and the second connection (3) of the electric motor (1). IN the switched on state, at least two of the switching elements (7, 8, 9, 10) authorise a current conduction for both current directions.

摘要： The invention relates to a circuit arrangement for controlling an electrical consumer (M), said arrangement being provided with a bridge circuit which comprises four electronic switches (V1, V2, V3, V4) and the consumer (M) which is arranged in the transversal leg of the bridge circuit, and a control circuit (uC) comprising control terminals for the four electronic switches. The control terminal for the first electronic switch (V1) is connected to the control terminal for the fourth electronic switch (V4) by means of a series connection consisting of a first capacitor (C1) and a first resistance (R1), and the control terminal for the third electronic switch (V3) is connected to the control terminal for the second electronic switch (V2) by means of a series connection consisting of a second capacitor (C2) and a second resistance (R2). The invention also relates to a method for switching an electronic switch by means of a control circuit (uC) comprising a control terminal for controlling the electronic switch which can either be switched ('tristate') as an input ('high impedance') or as an output ('low' or 'high'). The switching of the electronic switch from the conductive state to the non-conductive state and/or vice versa is carried out in two steps, namely the control terminal is switched from 'low' via 'high impedance' to 'high' or from 'high' via 'high impedance' to 'low'.

摘要： Described is a circuit for indicating the nearly discharged state of a battery (B) which comprises an inductive load (M), a controllable switch (T) and an indication element (LED), wherein, on the one hand, the battery (B), the inductive load (M) and the controllable switch (T) are connected in series and, on the other hand, the battery (B), the inductive load (M) and the indication element (LED) are connected in series. The controllable switch (T) is opened if the voltage of the battery (B) is smaller than a specified first threshold value, and is closed again only if the voltage of the battery (B) is larger than a specified second threshold value. The circuit is intended for small battery-operated electrical appliances with an electric motor having a higher current consumption than the indication element (LED), with the indication element (LED) requiring a higher voltage than the battery (B) in the nearly discharged state, for example electric shavers or electric toothbrushes, and having a battery (B) with only one cell and a light-emitting diode (LED), which is intended to indicate to a user the nearly discharged state of the battery (B).
