Abstract:
1. A method for assessing sealing of a housing of a servomotor, the servomotor comprising a motor unit producing movement of a mechanical component, a position-detecting unit detecting position of the mechanical component, which is removably connected to a first connector and a mechanical unit, which is removably connected to a second connector, and a manual control system, the mechanical unit comprising a communication space between the housing, the second connector, and the motor unit, the communication space being isolated and sealed relative to the mechanical unit, the method being implemented with the first and second connectors connected to respective cables to test sealing of the motor unit, the position-detecting unit, and the first and second connectors, wherein the method comprises: lowering pressure inside the housing, from an initial pressure to a set pressure, by operation of fluid suction means connected to the servomotor through an opening in the housing sealable by a plug, when the pressure inside housing is equal to the set pressure, determining pressure variation inside the housing over time, for a predetermined time interval, the fluid suction means being inoperative during the predetermined time interval, the fluid suction means being connected to the housing through a check device preventing any fluid exchange between the fluid suction means and the housing in a direction opposite a fluid suction direction; and assessing the sealing of the housing of the servomotor according to the pressure variation determined.
