摘要： An electric motor (10) has: a stator (12) and a rotor (14) having a shaft (87). The rotor (14) has a sensor magnet (82) having a number SP of sensor poles (71, 72, 73, 74) for generating a predetermined distribution of the magnetic flux density, such that SP=2, 4, 6, 8, etc. The motor also has at least two rotor position sensors (450, 455, 460, 465) for generating rotor position signals (B_S1, B_S2) characterizing the magnetic flux density, the rotor position sensors (450, 455, 460, 465) being arranged in the region (30) of the circumference of the sensor magnet (82). The motor also has an evaluation apparatus (32) that ascertains, from the rotor position signals (B_S1, B_S2), an absolute value (phi_el, phi_mech) for the rotational position of the rotor (14). A method of generating an absolute value for the rotational position of an electric motor is likewise described.

摘要： An arrangement (100) for specifying the pressure (64), produced by a pump (30) driven by an electric motor (31), includes a processor (116) which derives a target pressure value (64, 118) from an internal torque value (114) and a loss torque (108). The arrangement (100) further derives (112) the internal torque value (114) from a motor current value (110) and a motor constant ke.
