PROBLEM TO BE SOLVED: To provide a compact rotating electrical machine control device that has a smaller number of terminals and wires between a CPU and a driver IC.SOLUTION: Combined signal generation sections 41, 42, 43 correspond to a U coil 11, a V coil 12 and a W coil 13, respectively, and combine first command signals and second command signals generated by a command signal generation section 31 to generate combined signals. CPU output terminals 32, 33, 34 output the combined signals. Wires 51, 52, 53 are electrically connected at ends to the CPU output terminals 32, 33, 34, respectively, and at opposite ends to IC input terminals 61, 62, 63 of a driver IC 60, respectively. Gate signal generation sections 71, 72, 73 separate the combined signals input into the IC input terminals 61, 62, 63 to generate first gate signals as gate signals for MOSs 21, 22, 23 and second gate signals as gate signals for MOSs 24, 25, 26. |
