Abstract

See full text

A sealed actuator including stacked motor modules. Each motor module has a motor module housing, a motor stator attached to a respective motor module housing, a motor rotor in communication with a respective motor stator, and a stator seal disposed between the motor stator and motor rotor, surrounding the motor rotor and having a sealing surface interface, that interfaces with a respective sealing housing surface of the motor module housing, facing the motor rotor to seal the motor stator from the motor rotor. The motor module housings are stacked against each other and the sealing housing surface interfaced, at the sealing surface interface facing the rotors, to the respective stacked stator seals of the motor module housings forms a substantially continuous seal interface of the stacked motor modules sealed by the stacked stator seals to form a continuous barrier seal between the motor rotors and the motor stators.
