电动机控制装置
摘要：
一种用于控制电动机(2)的操作的电动机控制装置(3)具有操作温度估计器(31，33)和操作控制器(31，32)。操作温度估计器估计电动机的估计温度。操作控制器(31，32)在估计温度处于预定操作启动禁止范围(B)内时禁止启动电动机的操作，而在估计温度增加至操作启动禁止范围(B)中时允许继续电动机的操作。
摘要（英）：

A motor control apparatus 3 for controlling an operation of an electric motor 2 has an operational temperature estimator 31, 33 and an operation controller 31, 32. The operational temperature estimator estimates an estimated temperature of the electric motor. The operation controller 31, 32 disables to start the operation of the electric motor while the estimated temperature is within a predetermined operation start disable range B, and enables to continue the operation of the electric motor when the estimated temperature increases into the operation start disable range B.
