Abstract
A parking brake device is suitable for being installed in a casing of an electric machine that houses a rotary shaft and at least one rolling bearing for guiding the rotary shaft. The parking brake device includes an annular support suitable for being inserted between the rolling bearing and the casing. The annular support bears a parking brake mechanism to prevent the rotation of the rotary shaft relative to the casing, and a measurement device to measure the angular position or speed of the rotary shaft relative to the casing, and/or an electrical conduction device to route the electrical current between the rotary shaft and the casing.
