Abstract
The utility model discloses a permanent magnet motor which comprises a motor controller and a motor. The motor controller is electrically connected with the motor. The motor is a brushless motor and includes a rear cover, a stator wire frame, a magnet, a shaft support, a casing and a front cover, wherein the shaft support passes through the stator wire frame to be connected with the rear cover, the casing covers the stator wire frame, the front cover is fixed on the casing by a buckle structure, and the magnet is placed in the stator wire frame. The speed of the permanent magnet motor disclosed by the utility model can be adjusted steplessly. The permanent magnet motor is smaller in size and lighter in weight than the smallest ordinary DC brushless motor commonly used in the market at present, and the efficiency of the permanent magnet motor is about 15% higher than that of a conventional motor. The permanent magnet motor has the advantages of being energy-saving and environment-friendly, low in noise, long in service life, good in controllability and the like.
Description
Technical field
The utility model relates to the Micro & Special Motor Technology field, is specifically related to brushless and permanent magnet motor structure and replaces traditional magneto field.
Background technology
Existing electric tool product is a kind ofly by electromagnetic rotating formula or reciprocating few capacity motor, by transmission mechanism, to drive apparatus for work (working head), carries out the portable or portable tool of production of work.As hand electric drill, electric saw, electric planer and portable floor polisher, hay mover, sander etc.China's electric tool product, from tens kind 40 plurality of specifications of nineteen sixty-five, develops into current more than 200 kind, 300 plurality of specifications.From production quantity, China has become the big producing country of world's electric tool.
Traditional electric tool class motor is all to realize with series excited machine or the common brush DC motor that has, the demand of the development in root market to the requirement of motor is: volume is little, lightweight, torsion is large, life-span is long, the standard that security performance is high is analyzed, the series excitation air barrel motor of use exists volume large now, Heavy Weight, security performance is not high, efficiency is very low fully inconsistent with the mark of the energy-conserving and environment-protective of national requirements and market demand, and the common of use has brush DC motor average life short now simultaneously, the deficiency that torsion is little. and allow finished product air duct unclassified stores wasting phenomenon occur for this reason.
The utility model content
For the problems referred to above, the utility model aims to provide the brushless electric machine of a kind of special use on air duct, to make up conventional inner-rotor brushless motor in the situation that equal volume power does not reach requirement, the special-purpose brushless electric machine of several air ducts of a more special external rotor designed in conjunction with the advantage of internal rotor and external rotor.
For realizing this technical purpose, scheme of the present utility model is: a kind of magneto comprises electric machine controller, motor.Electric machine controller is electrically connected to motor, motor is brushless electric machine, comprise that bonnet, stator coil holder, magnetite, axle prop up, casing, protecgulum, axle props up through the stator coil holder and is connected with bonnet, stator coil holder outside is coated with casing, protecgulum is fixed on casing by buckle structure, and wherein magnetite is placed in the stator coil holder.
As preferably, also be provided with ball bearing before and after bonnet.
As preferably, after be covered with the locator card spring.
As preferably, after be covered with louvre.
As preferably, after be covered with the lead-out wire hole.
The beneficial effects of the utility model, can realize the motor stepless time adjustment, and the common DC brush motor of minimum commonly used is also little in the market for volume ratio, and it is light that weight is wanted, and efficiency will exceed 15% left and right than conventional motor; There is the advantages such as energy-conserving and environment-protective, low noise, long-life, controllability are good.
The accompanying drawing explanation
The explosive decomposition figure that Fig. 1 is motor of the present utility model;
The structural representation that Fig. 2 is motor of the present utility model;
The structural representation of the stereopsis face that Fig. 3 is motor of the present utility model;
Fig. 4 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Fig. 1,4, a kind of magneto of specific embodiment described in the utility model, comprise electric machine controller 8, motor 9.Electric machine controller 8 is electrically connected to motor 9, motor 9 is brushless electric machine, comprise that bonnet 2, stator coil holder 3, magnetite 4, axle prop up 5, casing 6, protecgulum 7, axle props up 5 and is connected with bonnet 2 through stator coil holder 3, stator coil holder 3 outsides are coated with casing 6, protecgulum 7 is fixed on casing by buckle structure, and wherein magnetite 4 is placed in stator coil holder 3.
As shown in Figure 2,3, bonnet 2 front and back also are provided with ball bearing 1 both can play the effect of fixed rotor, can reduce axle simultaneously and prop up the friction with bonnet.Bonnet 2 is provided with location jump ring 10, for bonnet is fixed.Bonnet 2 is provided with louvre 11, and the louvre of hollow out can form cross-ventilation the dissipation of heat of motor is gone out.Bonnet 2 is provided with lead-out wire hole 12, is convenient to the wiring of motor.
According to electric tool, now of DC direct current machine power and performance matching design, make with the little brushless electric machine of performance power volume, by brushless electric machine overall dimension, whole electric tool small product size is dwindled again, the change internal circuit makes its performance that surmounts existing electric tool and power, motor can dwindle 1/3, and whole product can dwindle 1/3 to 1/2 volume
The above; it is only preferred embodiment of the present utility model; not in order to limit the utility model, any trickle modification that every foundation technical spirit of the present utility model is done above embodiment, be equal to and replace and improve, within all should being included in the protection range of technical solutions of the utility model.
