Abstract
The utility model discloses a wire-wound disc type armature direct current motor, which solves the problems of air gaps, material consumption, heat radiation, etc. of a wire-wound disc type armature direct current motor by improving the shape and the structure of an armature winding and a magnetic yoke circular disc. The direct current motor is characterized in that a magnetic yoke circular disc presents an annular shape; rounded corner fan-shaped lug bosses and slots are uniformly distributed on the disc surface of the annular circular disc along the circumference; winding coils are respectively inlaid in the slots which are adjacent to the lug bosses; the curved surface of the outer edge of a whole armature presents an impeller shape. Compared with the existing wire-wound disc type armature motor, the motor having the structure can effectively reduce air gaps, increase effective magnetic flux and decrease leaky magnetic flux; the axial float problem generated when the motor runs is also overcome because of the attractive force of the magnetic yoke circular disc and permanent magnetic steel; the curved surface of the outer edge of the armature winding has an impeller-shaped structure, so material is saved, and the heat radiation conditions of the motor are also improved. The utility model can be widely used in fields of supplies, automobiles, household appliances, etc.
Description
Technical field
The utility model relates to a kind of wire-wound disc type armature DC motor.
Background technology
Wire-wound disc type armature DC motor has the short structure of axial length, good electromechanical properties (inertia is little, and torque pulsation is little, and is in light weight) and higher efficient, has obtained in fields such as office appliances, automobile and household electrical appliance to use widely.Wire-wound disc type armature DC motor is an axial air-gap, and its permanent-magnet steel has single ender and bilateral arrangement to lay form for two kinds.The existing introduction in Shanghai electrical micro-machine research institute (1994,77～87) " small and special electric machine is designed program " book.The bilateral arrangement of permanent-magnet steel can be shortened air gap, increases useful flux, improves the performance of motor.But bilateral arrangement adopts the magnet steel amount bigger, increases material consumption.The permanent-magnet steel single ender can be saved permanent magnetic material, also can shorten axial dimension.So permanent-magnet steel single ender mode is paid close attention to by people.Some patented technologies have adopted diverse ways and measure around permanent-magnet steel single ender mode, shorten air gap, increase useful flux.As clear 54-87806 of Japan Patent and the clear 54-1409061 of Japan Patent, iron wire is filled in the space between armature coil.The clear 60-5766 of Japan Patent is integral armature winding and yoke for another example.The former is poor to the motor adaptation of permanent-magnet steel single ender.It is unsatisfactory that latter's air gap dwindles, especially just all the more so to the more motor of the armature winding coil number of turn.In addition, disc-type electric motor adopts resin material with the armature winding curing molding mostly, exists heat dissipation problem.If adopt the clear 59-113729 of Japan Patent, the method that winding space is boxed out, then the method with front increase effective air gap magnetic flux contradicts.
Summary of the invention
How improving the structure of disc-type electric motor, make it effectively dwindle air gap, save magnetic material and good radiating condition is provided, is the technical barrier that this motor will solve.The utility model provides a kind of disc-type electric motor that improves armature structure, can effectively improve its comprehensive technical indexes.
The disc-type electric motor that the utility model provides comprises: armature winding, magnetic are gripped disk, rotor body, radiator shutter, permanent-magnet steel, brush, commutator, bearing, axle, front end housing, rear end cap, boss, groove, it is characterized in that magnetic grips disk ringwise, at the card upper edge of circular disk circumference evenly distribute fan-shaped boss in angle, garden and groove, inlay winding coil in the groove adjacent with boss, whole armature outer edge curved surface is the impeller shape.
Magnetic is gripped disk and is formed by the iron powder and the poured with epoxy resin of magnetic conduction, after inlaying winding coil in the groove on the yoke disk, with epoxy resin and non magnetic ore filler itself and commutator and axle are poured into an integral body, boss and magnetic are gripped disk together as the magnetic circuit of armature.
Compare with existing wire-wound disc armature motor, this electric motor structure can effectively shorten air gap, increases useful flux, reduces leakage flux.Because the gravitation of yoke disk and permanent-magnet steel, motor have also overcome the axial endplay problem when operation.Armature winding outward flange curved surface is the structure of impeller shape, has so both saved material, has also improved the radiating condition of motor.
