  "textContent": "A motor control device including a PWM control part is provided. The PWM control part has a two-phase complementary PWM control part, and when driving opening and closing of an opening/closing body, PWM-controls upper switching elements and lower switching elements of three phases in a three-phase inverter circuit based on an energization mode that sequentially switches among energized phases, which are two of the three phases, and a non-energized phase, which is a remaining one phase. The two-phase complementary PWM control part, in one of the energized phases, controls one of the upper switching element and the lower switching element by a PWM signal, and controls the other by a complementary PWM signal having a polarity opposite to the PWM signal, and, in the non-energized phase, controls one of the upper switching element and the lower switching element to be off, and controls the other by the complementary PWM signal.",
