Description
Technical field:
The utility model belongs to motor line, specifically a kind of external rotor torque motor.
Technical background:
At the equipment that uses torque motor, papermaking, cable, weaving, plastics, conveyer belt etc. are arranged at present, they all are the patterns of traditional common motor, formed by casing, stator, rotor etc., being installed in needs base support on the equipment, transmission power needs belt pulley, the structure that sprocket wheel etc. are complicated.Invent a kind of external rotor torque motor, eliminated above defective, necessary.
Summary of the invention:
For overcoming the prior art deficiency, the utility model provides a kind of external rotor torque motor, the technical scheme that adopts is: motor casing (1) is the rotor of motor, shell (1) inner chamber is equipped with stator (2), stator (2) is made up of soft magnetic material, stator (2) is provided with a plurality of axial ventilation holes (9), stator (2) embeds solenoid (3), stator (2) center is installed with back shaft (4), back shaft (4) is provided with the hole (10) of drawing lead (11), back shaft (4) left end passes the end cap (13) that bearing (12) are housed, right-hand member passes the end cap (6) that bearing (5) are housed, a left side, right end cap (13,6) be provided with ventilation hole (14,7), left and right sides end cap (13,6) be separately fixed at the two ends of shell (1).
The inner chamber right-hand member of shell (1) is provided with heat radiation does not have axle blower fan (8).
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Specifically describe by the utility model of embodiment below in conjunction with accompanying drawing.
Embodiment:
Shown in Figure 1, motor casing 1 is the rotor of motor, and shell 1 inner chamber is equipped with stator 2, and stator 2 is made up of soft magnetic material, stator 2 is provided with a plurality of axial ventilation holes 9, stator 2 embeds solenoid 3, and stator 2 centers are installed with back shaft 4, and back shaft 4 is provided with the hole 10 of drawing lead 11, back shaft 4 left ends pass the end cap 13 that bearing 12 is housed, right-hand member passes the end cap 6 that bearing 5 is housed, and left and right end cap 13,6 is provided with ventilation hole 14,7, and left and right sides end cap 13,6 is separately fixed at the two ends of shell 1.
The inner chamber right-hand member of shell 1 is provided with heat radiation does not have axle blower fan 8.
External rotor torque motor of the present utility model has and makes simply, has saved great deal of steel, the user is in the supporting construction that has saved the conventional motors complexity when equipment is installed, saved the belt wheel of transmission power, there is not belt, chain hidden danger in the running in sprocket wheel.Reduced the manufacturing cost of equipment greatly.A kind of external rotor torque motor of the present utility model by the requirement of different diameter of cylinder width, length, rotating speed, produces the cylinder torque motor of different size in manufacture process, be the rotation of shell cylinder because rotating magnetic field directly drives external rotor.Do not have drive disk assembly like this, do not have reactive loss, saved raw material and electric energy.
