Description
[technical field]
The utility model relates to the stator and the supporting shell of a kind of notch inner rotor motor outwardly.
[background technology]
The stator core of existing inner rotor motor, and though opening or half opening, the notch of its line embedding groove makes stator built-in line receive spatial constraints all towards inner periphery.Therefore, in middle and small motor was made, stator built-in line mostly adopted handwork at present, labour intensity is big, take man-hour many, human cost high.Simultaneously, this spatial constraints is also brought many difficulties to research and development, the application of the automatic coil inserting apparatus of stator, causes the automatic coil inserting apparatus complex structure of stator, high, the fluctuation of service of manufacturing cost.In a word, the backward situation of stator built-in line and occupying of motor manufacturing cost are high-leveled and difficult all relevant with the notch direction of existing stator core down in the middle and small motor manufacture process.
What be necessary explanation in advance is; Though the stator rabbet of existing outer-rotor permanent magnet motor is the outward circumference; As shown in Figure 1; But its existence does not influence the novelty and the creativeness of the utility model, because the range of application of the two is distinct, the interrelational form of stator and shell, the architectural feature of teeth groove also are far apart different.Especially, the tooth portion of the former stator is open slot towards air gap as far as air gap, and the utility model be yoke portion towards air gap, be the groove of remaining silent as far as air gap.
[utility model content]
The technical problem that (one) will solve
Limiting factor in making to present middle and small motor, the main purpose of the utility model be let inner rotor motor stator core notch outwardly, for hand insertion and rule automatically provide loose operating space.But notch can bring several problems that can not be ignored outwardly, must manage to solve: the one, and notch inevitable requirement teeth groove structure generation outwardly respective change, the tooth portion of stator core is elongated, the attenuation of yoke portion, and this can reduce the mechanical strength of stator core; The 2nd, it is that the stator repair work of main contents can't directly be carried out that the stator core inner closed makes to change coil windings; The 3rd, profit is covered all very outstanding when it is applied to magneto; Favourable part is that the inboard magnetic property of iron core is balanced, can eliminate torque pulsation effectively, and disadvantage is that the wire casing inner closed can increase the groove leakage reactance; Increase the time constant of circuit, and then influence the dynamic characteristic of electric machine control system.In addition, this novel stator is realized specialized production more easily, is necessary stator design is become the parts of a relatively independent globality, so that transportation, sale and installation.
(2) technical scheme that is adopted
The stator of a kind of notch inner rotor motor outwardly and supporting shell comprise stator core, coil windings, insulation liner, moulding slot wedge, supporting shell, fastener, it is characterized in that: the notch outward circumference of said stator core; Said coil windings is embedded in the wire casing from the outside via the notch of stator core or on the groove tooth; The notch of accomplishing the stator core of rule or coiling seals with the moulding slot wedge; The finished product stator is assemblied in the supporting shell through fastener, makes it to become detachable globality parts.
Further, the tooth portion of said stator core is at excircle, and yoke portion is at inner periphery, and wire casing is closed in the air gap side, and bottom land is circular arc.
Further, when this stator core was used for the internal rotor permanent-magnetic motor, the air gap side of wire casing is also dashed had the meniscus breach, increased problem to solve the groove leakage reactance.
Be to strengthen magnetic conduction and the mechanical support effect of slot wedge, the Cross-section Design of moulding slot wedge is " T " font, form by the resin mold pressing of mixing magnetic material, during assembling with the contact-making surface of coil, groove tooth on whole gluings.
Be for convenience detach, maintenance, adopt non-interference fit between supporting shell and the stator core.
For guaranteeing that supporting shell and stator core do not become flexible in axial and tangential, on the correspondence position of the two, be provided with vertical pin key groove and lateral pin Luo hole, use the key bar tight during assembling respectively with steady pin.
For defence press-fits, the mechanical shock in fastening, when dismounting, establish reinforcement at the fluting place of supporting shell, thicker trim ring cramp is laid at stator core fluting place.
The beneficial effect that (three) can produce
The one, be convenient to rule, coiling, can increase work efficiency, reduce manufacturing cost, can improve copper factor and rule quality again, also easily be automated production; The 2nd, can improve the magnetic property of air gap side, eliminate slot effect, reduce torque pulsation greatly, and then promote the overall performance of motor; The 3rd, effectively prevented the groove leakage reactance, do not influence the dynamic characteristic of motor; The 4th, be convenient to assembling, dismounting, maintenance, transportation and sales and recycling.
