Abstract
A split-phase starter for an electric motor having a casing made up of a casing body and a lid secured to the casing body, the casing body having a first casing and a second casing, a relay contact mechanism being arranged in the casing body, and a positive temperature coefficient thermistor being arranged in the second casing.
Claims7
A split-phase starter for an electric motor having a main winding and an auxiliary winding, the split-phase starter comprising:
- a starting relay including a relay coil and an associated relay contact means, the relay coil electrically connected with the main winding, and the relay contact means electrically connected with the auxiliary winding;
- a positive temperature coefficient thermistor connected in series with the relay contact means to form a series circuit;
- a casing body including a first casing and a second casing, the relay contact means being positioned in the casing body, and the positive temperature coefficient thermistor being positioned in the second casing;
- a lid secured to the casing body;
- the lid having a recess and a protrusion, the protrusion having a hole located in the center of the protrusion;
- a terminal board having a first end portion and a second end portion having a hole, the first end portion being secured to the second casing and fitted into the recess in the lid, the second end portion being secured between the second casing and the lid, the protrusion of the lid extending through the hole in the second portion of the terminal board;
- and
- a screw engaging the hole in the protrusion of the lid to secure the lid to the casing body.
A split-phase starter for an electric motor having a main winding and an auxiliary winding, the split-phase starter comprising:
- a starting relay including a relay coil and an associated relay contact means, the relay coil electrically connected with the main winding, and the relay contact means electrically connected with the auxiliary winding;
- a positive temperature coefficient thermistor connected in series with the relay contact means to form a series circuit;
- a casing body including a first casing and a second casing, the relay contact means being positioned in the casing body, and the positive temperature coefficient thermistor being positioned in the second casing;
- a lid secured to the casing body;
- the first casing is in the form of a cylinder having a hole defined by the walls of the cylinder;
- the casing body further including,
- a flange located at one end of the first casing, the flange having a recess and an end face;
- and
- a protrusion extending at the end of the casing body opposite the one end;
- and
- the second casing being integral with the flange.
