Abstract
The utility model relates to a heat-sinking structure for a flat sewing machine motor, comprising a directly driven servomotor (A-2), a casing (A-1) and an encloser (A-3) and also comprising a handwheel (B-1), wherein, the handwheel (B-1) is fixed on a shaft of the directly driven servomotor (A-2) and convexly arranged aside of the encloser (A-3); a fan blade (B-2) is arranged inside the handwheel (B-1). The utility model has the advantage that effective heat sink is provided for the motor under the condition that no components and power source are increased.
Description
Technical field
The utility model relates to a kind of sewing machine, relates in particular to the radiator structure of the flat electrical motor of sewing machine of direct-driving type.
Background technology
The flat sewing machine of direct-driving type is a kind of noise, the little and more energy-conservation sewing machine of vibration, and can adapt to multiple sewing work.
Motor of the prior art when work fully by the body natural heat dissipation but also be wrapped in the case air to be difficult for the circulation radiating effect very poor.Thereby motor for a long time in high temperature the work drive motor output torque can descend and can influence sewing performance, the life-span that can make motor of working in high temperature for a long time simultaneously reduces, and has influence on machine performance.
As seen from Figure 1: this machine is directly installed on directly-drive servo motor A-2 in the casing A-1 and by coupling and drives upward axle; Handwheel A-4 is for satisfying operator's manual needs, motor is wrapped up with case A-3 in order to protect motor and electric elements, but the handwheel major part protruding from outside the case.
Summary of the invention
The utility model technical issues that need to address provide a kind of radiator structure of flat electrical motor of sewing machine, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: directly-drive servo motor, casing, case; Also comprise a handwheel; Described handwheel fixed in position is on the axle of directly-drive servo motor and protrude from by the side of case; Flabellum is arranged in the handwheel;
Compared with prior art, the beneficial effects of the utility model are: provide an effective heat abstractor to motor under the situation that does not increase parts and power source.
Description of drawings
Fig. 1 is a flat electrical motor of sewing machine mounting structure schematic diagram in the prior art;
Fig. 2 is a handwheel structural representation in the utility model;
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
By Fig. 1, Fig. 2 as seen: the utility model comprises: directly-drive servo motor A-2, casing A-1, case A-3; Also comprise a handwheel B-1; Described handwheel B-1 fixed in position is on the axle of directly-drive servo motor A-2 and protrude from by the side of case A-3; Flabellum (B-2) is arranged in the handwheel (B-1);
Have the air admission hole B-3 corresponding at described handwheel B-1 edge with blade quantity.
The utility model operation principle is: by the rotation of the flabellum on the driven by motor handwheel, air is produced flow, the air admission hole B-3 that opens by the handwheel edge begins inwardly to replenish air simultaneously, can be continuously to motor cooling air.
Claims (2)
1. the radiator structure of a flat electrical motor of sewing machine comprises: directly-drive servo motor (A-2), casing (A-1), case (A-3); It is characterized in that: also comprise a handwheel (B-1); Described handwheel (B-1) fixed in position is by the side of case (A-3) is gone up and protruded to the axle of directly-drive servo motor (A-2); Flabellum (B-2) is arranged in the handwheel (B-1).
