Abstract
A brushless rotary actuator comprises a housing including a motor housing defining a cavity for a motor assembly and a cover defining a cavity for a gear assembly. The motor assembly includes a rotor and a stator with a plurality of bobbins. A clip in the form of a ring plate is seated against the bobbins for retaining the bobbins on the stator. Fingers formed on the ring plate are fitted into respective slots defined by respective bobbin terminals. A circuit board is seated in the housing against an interior shoulder of the motor housing. A plate is seated in the housing against a peripheral rim of the motor housing in a spaced relationship above the circuit board.
