摘要： The disclosure relates to a method for adjusting an operational performance of an electric machine (12). The electric machine (12) comprises a stator (14) and a rotor (16), wherein the stator (14) comprises a set of N phase windings (U, V, W, X, Y). Each of the N phase windings (U, V, W, X, Y) forms p poles around the circumference of the stator (14) and, each pole is formed by at least one winding sector (18). The method comprises deactivating a first sub-set of winding sectors (18), wherein the first sub-set of winding sectors (18) comprises at least one winding sector (18), and triggering an AC drive signal for a second sub-set of winding sectors (18) such that the rotor (16) is rotated using the winding sectors (18) of the second sub-set. Furthermore, the disclosure is directed to a corresponding data processing device (24), a corresponding computer program (32) and a corresponding computer-readable storage medium (30). Moreover, an electric drive system (10) is presented.

摘要： A permanent magnet generator voltage regulation system (10) controls the output voltage of a permanent magnet generator (14). The output voltage of the permanent magnet generator is controlled by configuring the electrical connection of the stator coils. A monitoring device (18) monitors the output voltage generated by the PMG, and a controller (20) selectively configures the stator coil configuration based on the monitored output voltage. A switch array (22) having a number of switches is connected to the stator coils, the switches being controlled by the controller to configure the electrical connection of the stator coils. For instance, to maximize output voltage generated by the PMG, the controller causes the switch array to connect the stator coils in series with one another. To reduce the output voltage, the controller causes the switch array to connect at least some of the stator coils in parallel with one another. In this way, the output voltage of the permanent magnet generator can be coarsely controlled.

摘要翻译：永磁发电机电压调节系统（10）控制永磁发电机（14）的输出电压。通过配置定子线圈的电气连接来控制永磁发电机的输出电压。监视装置（18）监视由PMG产生的输出电压，并且控制器（20）基于所监视的输出电压选择性地配置定子线圈配置。具有多个开关的开关阵列（22）连接到定子线圈，开关由控制器控制以构成定子线圈的电连接。例如，为了使PMG产生的输出电压最大化，控制器使开关阵列将定子线圈彼此串联连接。为了降低输出电压，控制器使开关阵列彼此并联连接至少一些定子线圈。以这种方式，可以粗略地控制永磁发电机的输出电压。

摘要： Disclosed is a magnetic gear apparatus including a rotational magnetic force generator configured to generate rotational magnetic force, a magnetic path creator having a hollow shape so as to be provided at an outer circumferential surface of the rotational magnetic force generator, the magnetic path creator being configured to create a magnetic path of the rotational magnetic force generated from the rotational magnetic force generator, and a rotor provided at an outer circumferential surface of the magnetic path creator, the rotor including permanent magnets provided at an inner circumferential surface thereof and being rotatable by the rotational magnetic force. The rotational magnetic force generator includes one or more pairs of alternately arranged N-pole units and S-pole units. A torque of the rotor may vary as the number of the N-pole units and the S-pole units is adjusted.
