Abstract
A servo motor assembly having a cylindrical motor casing with connector terminals extending axially from one end and a driving shaft from the opposite end. An annular slotted ring has the connector terminals received therethrough and the ring is axially pressed into a housing having a connector receptacle for connection to a power source. The ring has projections on the outer periphery to frictionally retain the motor and ring in the housing and compress the ring to frictionally engage the motor casing and absorb any inertial reaction torque therebetween. Electrical leads are connected from the motor terminals to the receptacle on the housing.
Claims12
A servo motor assembly comprising:
- (a) a motor having an outer casing with at least one motor electrical terminal thereon and including a rotating shaft for driving connection to a load;
- (b) a housing having a mounting surface on the interior thereof and including at least one housing electrical terminal thereon adapted for external electrical connection thereto;
- (c) an annular mounting member having first surfaces disposed on the inner periphery thereof and second surfaces on the outer periphery thereof, wherein said annular member is radially compressed by contact of said second surfaces with said housing mounting surface, thereby causing said first surfaces to frictionally engage said casing and said second surfaces to frictionally engage said mounting surface for preventing relative rotation between said motor and said housing;
- and,
- (d) upon assembly of said annular member and said casing in said housing, said at least one motor electrical terminal is connected to said at least one housing electrical terminal.
