Abstract
The utility model relates to a brushless motor used in an industrial sewing machine. The brushless motor adopts an outer rotor type brushless motor including a stator, a motor rotating shaft and an outer rotor, wherein the outer rotor is in interference linkage with the motor rotating shaft; the motor rotating shaft is connected with the main shaft of the sewing machine through a coupler; and the stator is arranged in the main body of the sewing machine through a mounting flange. The utility model adopts an outer rotor type brushless motor, and the outer rotor can replace the hand wheel of the sewing machine in the prior art, thereby simplifying the structure, reducing the volume and the length of the main body, and further enlarging the low speed rotating torque. The mounting hole on the mounting flange is an elliptical hole; when the needle stopping position is adjusted, the elliptic mounting hole is convenient for the rotational adjustment of the mounting flange; and the position of a needle stopping position sensor can be adjusted through adjusting the mounting flange, thereby facilitating the adjustment and improving the operational reliability.
Description
Technical field

The utility model content
Technical problem to be solved in the utility model provides the industrial sewing machine brushless electric machine of the big and good reliability of a kind of less, low speed torque of taking up room.
For solving the problems of the technologies described above, industrial sewing machine brushless electric machine of the present utility model comprises: this brushless electric machine is the brushless electric machine of external-rotor-type, and it comprises: stator, machine shaft and external rotor; External rotor and machine shaft interference fit joint, machine shaft links through shaft coupling and machine spindle; Stator is in mounting flange is arranged at the sewing machine fuselage.
In the technique scheme, mounting flange is provided with and stops needle position sensor; On the shaft coupling relative, be provided with inductive magnetic steel with mounting flange.
In the technique scheme, the installing hole on the mounting flange is an elliptical aperture.
The utlity model has positive effect: (1) industrial sewing machine brushless electric machine of the present utility model, adopt the brushless electric machine of external-rotor-type, the alternative sewing machine handwheel of the prior art of its external rotor simplifies the structure, dwindle volume and fuselage length, thereby increased low speed torque.(2) in the utility model, the installing hole on the mounting flange is an elliptical aperture.When stopping the pin position according to the correspondence position relation adjusting that stops needle position sensor and inductive magnetic steel, oval installing hole is convenient to rotate the adjusting mounting flange, regulate the position of stopping needle position sensor by the mode of regulating mounting flange, made things convenient for adjusting work, improved its functional reliability.
Description of drawings
Fig. 1 is the structural representation of industrial sewing machine of the prior art with brushless electric machine;
Fig. 2 is the structural representation that the industrial sewing machine among the embodiment 1 is used brushless electric machine;
Fig. 3 is that A among Fig. 2 is to view.
Embodiment
(embodiment 1)
