A rotary electrical machine control apparatus is provided which controls drive of a rotary electrical machine having a plurality of winding sets. The apparatus includes inverters that are provided so as to respectively correspond to the winding sets, a temperature detection element that detects a base element that is used as a base for estimation of inverter temperatures, which are temperatures of the inverters, and a control section that has a temperature estimation section that estimates the inverter temperatures based on the base temperature and a temperature change amount generated due to current application to the inverters. On-resistance of the switching elements of the first inverter is smaller than on-resistance of the switching elements of the second inverter. The temperature detection element is disposed in an area, a distance between the area and the first inverter being shorter than a distance between the area and the second inverter.
