    • A motor driving control device that achieves as high as possible phase coil energization level while preventing thermal destruction of the power switching element by using precise thermal detection of a portion of the power switching element inside a switching module of the control device. An electric power loss Lt at the switching element is used for calculating a saturation temperature Tjgoal. On the basis of the saturation temperature, Tjgoal, and a time constant &tgr; of temperature rise, an instant junction temperature Tjnow is calculated. A difference Error between the instant junction temperature Tjnow and an upper temperature limit value Tjmax is calculated. In a motor locked condition, a coefficient Kt is calculated for the target torque, the target torque being equal to the required torque multiplied by Kt. Kt is based on the Error for calculating the target torque. If Error is greater than or equal to a predetermined value, K3, Kt is set to be 1, even if Kt is in excess of 1. If Error is less than or equal to 0 , Kt is set to be zero.
    • 一种电动机驱动控制装置,其通过对控制装置的开关模块内部的电力开关元件的一部分进行精确的热检测来防止电力开关元件的热破坏,从而实现尽可能高的相线圈励磁电平。 开关元件的功率损耗Lt用于计算饱和温度Tjgoal。 在饱和温度Tjgoal和时间常数tgr的基础上, 的温度上升,计算即时结温Tjnow。 计算出瞬时结温Tjnow与上限温度限值Tjmax之间的误差。 在电动机锁定状态下,针对目标转矩计算系数Kt,目标转矩等于所需扭矩乘以Kt。 Kt是基于计算目标扭矩的误差。 如果误差大于或等于预定值,则K3,Kt设置为1,即使Kt超过1.如果误差小于或等于0,Kt设置为零。
