摘要： The control circuit of an electric motor, which has at least one phase (2) supplied with high voltage and has a defined high-voltage zone (zone HV), is provided with a controller for the supply current of the phase with a nominal-value current, and has means for measurement (22, 24) of the supply current, which means produces a first analog signal (l
M ), whose value corresponds to the measured current, wherein an electronic control unit (6A) is arranged in a low-voltage zone (zone LV), and having an analog/digital converter (36) for conversion of the first analog signal or of some other analog signal, which acts as the first analog signal, to an equivalent digital signal (ΔΙ*), which is supplied to the electronic control unit. The control circuit is characterized in that the means for measurement is formed by an output resistor (22), which is arranged in series with the phase, and by a differential amplifier (24), the two inputs of which are respectively connected to two contacts of the output resistor; in that the analog/digital converter (36) is arranged in the high-voltage zone, a conductive disconnecting element (38) is arranged between the analog/digital converter and the electronic control unit, and in that the control circuit has, inter alia, a voltage converter (40) which produces a floating low voltage (LVFL) in the high-voltage zone, which floating low voltage (LVFL) supplies the analog/digital converter.

摘要： The invention relates to a parallel robot (2) of the SCARA type with a base or a body (4), attached to which are two articulated elements (12, 14), which are respectively formed by an arm (16, 18) and a lower arm (17, 19), which are connected by a joint and are attached in such a way as to be rotatable about one and the same geometrical axis (26).  This robot is characterized in that the two articulated elements are respectively attached to two annular segments (22, 24), which respectively form two movable parts of a circular motor, the stator (6) of which at least partially forms the body, wherein these two movable parts are assigned to one and the same circular path (8) of the stator.  The two movable parts are preferably guided by one and the same guide (42), in order to ensure that these two movable parts rotate very precisely about the same geometrical axis.
