Abstract
The utility model relates to a rare-earth brushless direct-current three-axis motor, belonging to the technical field of direct-current motors, and aims at providing a rare-earth brushless direct-current three-axis motor capable of driving two driven devices simultaneously. The motor comprises an end cap, a casing, a coil stator, a rotor, a driving shaft, a key, an electromagnetic clutch, a driven shaft, a bearing I, a bearing II and a cover plate, wherein the end cap is connected with the casing; the coil stator and the rotor are mounted in the casing; the rotor is connected with the driving shaft; the driving shaft is connected with the electromagnetic clutch through the key; a housing of the electromagnetic clutch is connected with the driven shaft; the bearing I is mounted in an inner hole of the driven shaft and connected with the driving shaft; and the bearing II is mounted in an inner hole of the end cap and connected with the driven shaft. According to the utility model, the rare-earth brushless direct-current three-axis motor adopts a rare-earth permanent magnet while a brush set is omitted, and is capable of driving the two driven devices simultaneously, having the advantages of simple and compact structure, low manufacturing cost, low noise and simple subsequent maintenance and long service life.
Description
Technical field
The utility model belongs to DC Brushless Motor technical field, is specifically related to a kind of rare earth brushless direct-current three axle motor.
Background technology
The electric motor system generally using is in the market all by magnetic pole of the stator coil windings, rotor magnetic pole coil winding, commutator, brush, casing, the formations such as bearing.After energising, stator and rotor-exciting produce magnetic field, brush and commutator sliding contact, and for rotor winding provides armature supply, rotor relative stator is rotated and is produced power, drives external load equipment to realize mechanical movement.Current this motor can only be realized single output, drives single slave unit, if need drive two slave units simultaneously, needs separately to add other mechanical devices, causes final device structure complicated, and manufacturing cost is high, and noise is large, safeguards the shortcomings such as complicated.
Summary of the invention
The purpose of this utility model is the shortcoming that overcomes prior art, and a kind of rare earth brushless direct-current three axle motor that can simultaneously drive two slave units are provided.
For achieving the above object, the technical solution adopted in the utility model is:
1, a kind of rare earth is brushless three axle motor, comprise end cap, shell, also comprise coil stator, rotor, driving shaft, key, electromagnetic clutch, driven shaft, screw I, bearing I, bearing I I, screw II and cover plate, described end cap is connected with shell, coil stator is installed in shell, rotor, rotor is connected with driving shaft, on driving shaft, have keyway, by key, connect electromagnetic clutch, electromagnetic clutch shell is connected by screw I with driven shaft, driven shaft endoporus is equipped with bearing I, bearing I is connected with driving shaft, end cap endoporus is equipped with bearing I I, bearing I I is connected with driven shaft, cover plate is connected with end cap by screw II.
Compared with prior art, the utility model adopts rare earth permanent magnet, cancels brushgear, simple and compact for structure, and can realize and drive two driven shafts simultaneously, thus drive need two kinds of functions movable machinery do single or move simultaneously.The utility model manufacturing cost is lower, and noise is little, and follow-up maintenance is simple, and strengthen useful life.
Accompanying drawing explanation
Fig. 1 is rare earth brushless direct-current three axle motor generalized sections.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Embodiment 1
As shown in Figure 1, the brushless three axle motor of a kind of rare earth of the present embodiment, comprise end cap 1, shell 2, also comprise coil stator 3, the rotor 4 that contains rare-earth permanent magnet, driving shaft 5, key 6, electromagnetic clutch 7, driven shaft 8, screw I9, bearing I 10, bearing I I11, screw II12 and cover plate 13, described end cap 1 is connected with shell 2, coil stator 3 is installed in shell 2, rotor 4, rotor 4 is connected with driving shaft 5, on driving shaft 5, have keyway, by key 6, drive the interior excitation magnetic sheet of electromagnetic clutch 7 to rotate, electromagnetic clutch 7 shells are connected by screw I9 with driven shaft 8, driven shaft 8 endoporus are equipped with bearing I 10, bearing I 10 is connected with driving shaft 5, end cap 1 endoporus is equipped with bearing I I11, bearing I I11 is connected with driven shaft 8, cover plate 13 is connected with end cap 1 by screw II12.
Motor internal arranges hall sensing element, utilizes rotating speed and the rotating of automatically controlled control motor.The closure of automatically controlled also solenoidoperated cluthes of while.When clutch power-off, the inner excitation magnetic sheet of clutch and driving shaft are servo-actuated, and the clutch outer member being connected with driven shaft and driving shaft are not servo-actuated, after electromagnetic clutch energising, the inner excitation magnetic sheet of clutch and clutch outer member, because adhesive becomes one, make driven shaft and driving shaft servo-actuated, so by energising and the power-off of electromagnetic clutch, realize the output of driven shaft, thereby realize, drive respectively a load to work independently or drive two loads to work simultaneously simultaneously.
