Brushless Direct Current Actuator with Clip for Retaining Bobbins

An actuator comprising:

• a housing defining a cavity;
• a motor mounted in the cavity in the housing, the motor including a rotor including a rotor shaft and a stator including at least one bobbin;
• a plate in the cavity in the housing and seated against the bobbin and secured to the stator for retaining the bobbin on the stator;
• a gear assembly located in the cavity in the housing and coupled to the rotor shaft;
• and
• an output shaft extending into the cavity in the housing and coupled to the gear assembly.

A clip for retaining a plurality of bobbins on a stator comprising:

• a ring plate seated against the stator and the plurality of bobbins, the ring plate being undulated and defining a plurality of curved regions overlying the plurality of bobbins respectively;
• a plurality of spaced-apart alignment fingers extending outwardly from an exterior face of the ring plate and adapted to be fitted in respective slots defined on the respective bobbins;
• and
• a plurality of first through-holes defined in the plate adapted to receive respective screws for securing the ring plate to the stator.
