摘要： A variable-flux motor drive system including a permanent-magnet motor including a permanent magnet, an inverter to drive the permanent-magnet motor, and a magnetize device to pass a magnetizing current for controlling flux of the permanent magnet. The permanent magnet is a variable magnet whose flux density is variable depending on a magnetizing current from the inverter. The magnetize device passes a magnetizing current that is over a magnetization saturation zone of magnetic material of the variable magnet. This system improves a flux repeatability of the variable magnet and a torque accuracy.

摘要： A control system for a motor includes a current regulation controller for generating a terminal voltage command. The terminal voltage command is used for converting a supply voltage to a three phase voltage to power a motor. The control system also includes a terminal voltage command feedback module for controlling the terminal voltage command. The terminal voltage command feedback module compares the terminal voltage command to a determined voltage limit of the supply voltage and generates a d-axis current adjustment command in accordance with the comparison. The d-axis current adjustment command is used for reducing the terminal voltage command below the determined voltage limit. The control system also includes a summer coupled with the terminal voltage command feedback module. The summer adds the d-axis current adjustment command to a d-axis current command received from a lookup table.

摘要： When the torque command value is zero, a set point of DC current for an inverter is calculated to obtain a difference between the set point and a detected DC current so that an error in magnetic pole position may be estimated and corrected. By correcting the magnetic pole position, unwanted power running and regenerative torque of the motor can be avoided and unnecessary charge or discharge to or from a battery can be prevented.

摘要： Under a low load condition, a produced torque is small and a synthetic current command I* with respect to an armature of a servomotor is small so that a magnitude in a negative direction of a reactive current command Id* determined by Id*=−|I*|·sin θ is small. As a result, under the low load condition, the synthetic current flowing through the armature can be small, and generation of wasteful heat can be suppressed. Further, under a high load condition, because a q-axis current Iq that produces the torque is large, voltage saturation is liable to occur. However, at the same time, the overall current command I* is large under the high load condition, and Id* is large in the negative direction. Therefore, a large reactive current Id can be flowed in the negative direction, and voltage saturation under the high load condition can be effectively prevented.
摘要翻译：在低负载条件下，产生的转矩小，并且相对于伺服电动机的电枢的合成电流指令I *小，使得由Id * = - |确定的无功电流指令Id *的负方向的大小我* |·罪恶是小。结果，在低负载条件下，流过电枢的合成电流可以很小，并且可以抑制浪费热的产生。此外，在高负载条件下，由于产生转矩的q轴电流Iq大，容易发生电压饱和。然而，同时，在高负载条件下，总电流指令I *大，Id *在负方向大。因此，大的无功电流Id可以在负方向流动，并且可以有效地防止在高负载条件下的电压饱和。
