To provide revolving electric motor equipment capable of quickly stopping even a revolving body having a relatively large inertia force at the halt hour of a revolving electric motor.
A hydraulic motor 11 connected to the driving shank of a revolving electric motor 10 revolvingly driving a rotor and a pair of relief valves 14a, 14b mutually reversely connected to each other are connected between a pair of ports of the hydraulic motor 11. A pair of check valves 15a, 15b reversely connected mutually are parallelly connected to a pair of relief valves 14a, 14b and respective reverse connection points 16a, 16b are connected to a hydraulic fluid source 17 respectively, the hydraulic fluid from the source 17 is supplied to one side vacuum port in the hydraulic motor 11 by especially the inertial rotation of the rotor at the time of the rotation stop by the revolving electric motor 10 and the other port in the overpressure is provided with a brake circuit 13 controlling the relief valves 14a, 14b under these preset pressure.
