Abstract
A driving control device of a brushless motor includes an inverter circuit having: first arm-side switching elements that are connected between respective phases of respective armature coils of the brushless motor and one terminal of a power supply; and second arm-side switching elements that are connected between respective phases of the respective armature coils and the other terminal of the power supply, and a control unit, wherein, in a short-circuit braking according to a short-circuit braking signal, the control unit outputs a signal of turning off all the first arm-side switching element and outputs a signal of controlling the at least one of the second arm-side switching elements to perform a switching operation and turning on the other second arm-side switching elements.
