Existing permagnetic synchronous motor, if application number is 201320829440.9 disclose a kind of permanent-magnet synchronous enabling gate machine, its primary structure is arc type, and rotor block and output shaft are provided separately.Its defect is because rotor block is thinner, and rotor block and output shaft bonding strength not, cannot control very well in the perpendicularity of assembling and operation transfer daughter and output shaft; Separately because arc type bearing outer wall installs the ultrathin big-diameter bearing of fixing needs, its noise is comparatively large, and price is higher, and intensity is relatively low.
Summary of the invention
The purpose of this utility model is to overcome defect of the prior art, there is provided a kind of not only meeting high efficiency, but also having on enough mechanical strength bases, make the thickness ultrathin of elevator door motor, and then make elevator door-motor design more compact ultra-thin permanent-magnet synchronous door lifter motor.
The utility model is achieved in that a kind of permanent-magnet synchronous door lifter motor, comprise chassis body, cabinet cover, rotor block, magnet steel, stator and stator winding, position transducer, it is characterized in that: described rotor block comprises the circular bottom wall of level, the surrounding of described circular bottom wall is upwards connected with cylindrical lateral wall, the middle part of described circular bottom wall is provided with the rotating shaft weight body raised up, the output shaft protruded is provided with downwards below the middle part of described circular bottom wall, clutch shaft bearing room is provided with in described chassis body, described clutch shaft bearing indoor are fixed with clutch shaft bearing, described rotating shaft weight body is connected with described chassis body with clutch shaft bearing room by described clutch shaft bearing, the second bearing chamber is provided with in described cabinet cover, described second bearing chamber internal fixtion has the second bearing, described output shaft is connected with described cabinet cover with the second bearing chamber by described second bearing, described circular bottom wall and cylindrical lateral wall, circular bottom wall and rotating shaft weight body and output shaft are connected as a single entity, the top of described rotating shaft weight body is provided with aluminium head, and described aluminium head is provided with magnetic grain, and described position transducer to be fixed on described chassis body and to be positioned at above described magnetic grain.Described magnet steel is fixed on the cylindrical side of described cylindrical lateral wall; Described stator and stator winding are fixed on the sidewall of described chassis body, and described magnet steel is between described cylindrical lateral wall and described stator and stator winding.
The cross sectional shape of described rotor block is in falling " towel " font.
The total height of described rotor block is 31 ~ 40mm.
Described clutch shaft bearing is arranged on the inwall of described clutch shaft bearing room.
The beneficial effects of the utility model are: due to the rotating shaft weight body of the utility model rotor block and output shaft one-body molded, well control the perpendicularity between rotating shaft weight body and output shaft, improve the intensity of rotor block simultaneously, make thickness of the present utility model very little, a machine integral thickness can be reduced, and ensure good intensity; The utility model can be directly installed on a machine backboard.
