Abstract: The present invention relates to a braking system for an electric motor, the braking system comprising: a chassis; and at least one brake supported by the chassis, the brake comprising: at least one brake disk connected via a fluted connection to a shaft driven by the motor; an armature that is movable in translation along an axis of rotation of the shaft; a plurality of armature-guiding spacers, at least one of the spacers being engaged at one end in a corresponding housing in the chassis, so as to enable the chassis to take up torque that is exerted on the brake during braking; a plurality of springs for urging the armature against the disk; and. an electromagnet which, when powered, attracts the armature and moves it away from the disk against the action of the springs.
