    摘要： A first inverter and a second inverter supply two coil sets forming a three-phase motor with AC voltages, which are the same in amplitude but shifted by 30° in phase. Current detectors detect phase currents supplied from the inverters to the coil sets. Temperature estimation sections estimate temperatures of the inverters or the coil sets based on an integration value of the phase current detection values. A current command value limitation section limits upper limits of current command values of both coil sets based on the estimated temperatures Tm1 and Tm2. Thus, the inverters and the coils sets are protected from overheating without increasing torque ripple.

    摘要： A system and method for preventing thermal damage to an electric motor in a vehicle includes arrangements for monitoring the motor and detecting a cycle of the motor. If the cycle occurred within a predetermined increment time, a cycle count is incremented. If no cycle occurs for a predetermined decrement time, the cycle count is decremented if the cycle count is greater than zero. If the cycle count is at least equal to a cycle limit, power operation of the motor is deactivated for at least the decrement time. The method may include continuously calculating energy consumed by the motor and, if the energy consumed exceeds one or more allowable energy thresholds, setting the cycle count equal to the cycle limit. The method may further include detecting a failure condition and setting the cycle count equal to the cycle limit when the failure condition is detected.

    摘要翻译： 用于防止对车辆中的电动机的热损伤的系统和方法包括用于监测电动机和检测电动机的循环的装置。 如果循环发生在预定的增量时间内，则循环计数增加。 如果在预定的减量时间内没有发生循环，则如果循环计数大于零，则循环计数递减。 如果循环计数至少等于循环限制，则电机的功率运行至少在减少时间内停用。 该方法可以包括连续计算电动机消耗的能量，并且如果消耗的能量超过一个或多个允许的能量阈值，则将循环计数设定为等于循环极限。 该方法还可以包括当检测到故障条件时检测故障条件并将周期计数设置为等于循环限制。
