Abstract: In order to reduce the cabling complexity of an electric motor having an encoder, an electric motor which can be connected to a control unit in order to receive an actuating signal from the control unit has an encoder port which is designed to receive an encoder signal from an encoder. Furthermore, the electric motor has a signal port which is designed to transmit the encoder signal to the control unit.

Abstract: To utilize and protect a mechanical load torque range of a servo drive in combination with a pump, a control unit is given a target system pressure as a reference variable and an actual system pressure as a control variable. An electric motor torque acting on a pump of the servo drive is specified by the control unit to an electric motor of the servo drive, a volume flow at the hydraulic load is generated by the pump, by which a mechanical load torque sets it at the electric motor and the actual system pressure is produced in the hydraulic load via the volume flow. A dynamic system variable of the hydraulic system is transmitted to the limiting unit. The limiting unit limits the motor torque transmitted by the control unit to the electric motor as a function of the value of the system variable.

Abstract: The different electrical components and cables arranged in the B flange of an electric motor can be installed only with difficulties and are complicated and time-consuming due to the restricted space conditions in the B flange. In order to improve this, it is proposed to recess the B flange's 3 front side 10 facing away from the electric motor 1 at least in sections with respect to an imaginary surface normal to the longitudinal axis 15 of the electric motor 1 in the direction toward the motor housing 2, and to shape the B flange cover's 9 front face resting against the B flange 3 in a mirror-inverted manner to thereby improve the accessibility to the inside of the B flange 3.
