Abstract
A motor may include a coil bobbin having a drum part around which a winding is provided, a terminal block formed on an outer periphery of the coil bobbin, at least a pair of terminal pins which are protruded from a first wall face of the terminal block, and a groove part formed in the first wall face of the terminal block and is opened to a second wall face of the terminal block that is perpendicular to the first wall face. Both ends of the winding are respectively bound to a pair of the terminal pins from the second wall face side through the groove part of the terminal block. A stator core may be utilized instead of the coil bobbin. In this case, the terminal block may be fitted to the stator core.
Claims12
A motor comprising:
- a coil bobbin which includes a drum part around which a winding having a first end and a second end is provided;
- a terminal block which is formed on an outer periphery of the coil bobbin comprising:
- a first wall face for attaching at least a pair of terminal pins;
- a second wall face which is formed to be extended from the drum part and perpendicular to the first wall face;
- a groove part which is formed in the first wall face and is opened to the second wall face;
- and
- a chamfered part which is formed on an edge part formed by the groove part and the first wall face over a portion of a passage for the first end and the second end of the winding;
- at least a pair of the terminal pins which are protruded from the first wall face of the terminal block;
- and
- wherein the first end and the second end of the winding are gradually approached to the pair of terminal pins from the second wall face side through the groove part and the chamfered part between the groove part and the first wall face of the terminal block to be respectively bound to the pair of terminal pins.
A motor comprising:
- a stator core which includes a plurality of pole teeth around which a winding having a first end and a second end is provided;
- a terminal block which is provided on an outer peripheral side of the stator core comprising:
- a first wall face for attaching at least a pair of terminal pins;
- a second wall face which is formed to be extended from the drum part and perpendicular to the first wall face;
- a groove part which is formed in the first wall face and is opened to the second wall face;
- and
- a chamfered part which is formed on an edge part formed by the groove part and the first wall face over a portion of a passage for the first end and the second end of the winding;
- at least a pair of the terminal pins which are protruded from the first wall face of the terminal block;
- and
- wherein the first end and the second end of the winding are gradually approached to the pair of terminal pins from the second wall face side through the groove part and the chamfered part between the groove part and the first wall face of the terminal block to be respectively bound to the pair of terminal pins.
