Abstract
The utility model relates to a permanent magnetic type disc shape DC motor which is characterized in that a rotor is a winding rotor disc frame which is fixed on a motor shaft in the radial direction, and a stator is a housing whose circular deep grooves produced by the distribution of the inner wall is fixedly provided with magnetic steel. The utility model adopts a circular-arranged fan-type NdFeB permanent magnet as the stator, which forms a plane circular magnetic confining field with the disc winding rotor; therefore, the effective area where the rotor cuts the magnetic field reaches the maximum extent, the torque is maximum, and the armature consisting of the rotor disc frame is characterized in lightness, small inertia, low noise, large torque force and wide speed range. The utility model has the advantages of small volume, high efficiency and wide application range.
Description
Technical field: the utility model relates to machine field, especially a kind of magneto disc shape DC motor.
Background technology: the present general motor of use of institute, its rotor is that iron core, the stator of outer winding group is the silicon steel sheet that stamp laminates.This motor can only be made cylindric or analogous shape, and its structure is more single, and weight, volume ratio are bigger, and cost is than higher, and the technology more complicated.
Summary of the invention: the purpose of this utility model is to overcome the deficiency of prior art, provide a kind of simple in structure, volume weight is little, efficient is high, cost is low and adopt the magneto disc shape DC motor of Fe-B rare-earth permanent magnet as magnet steel.
This rotor DC machine is configured to for radially being packed in the rotor disk that is tied with winding on the motor shaft and on it, this winding is packed on the rotor plate rail by the coil holder that winding is packed on the rotor plate rail, winding is the fan type, and be distributed on the rotor plate rail, winding can be at the single face of rotor plate rail, also can be for the rotor disk frame two-sided.Stator is a casing, and uniform being shaped in ring-type deep trouth and its is fixed with magnet steel on the casing inner wall, and this magnet steel is a Fe-B rare-earth permanent magnet, and magnet steel also can be packed in the casing, also can be packed in respectively in upper and lower two casings.
Advantage of the present utility model and effect are: 1. magnet steel adopts Fe-B rare-earth permanent magnet, makes electric efficiency can reach more than 80%, and mechanical loss is few, and copper loss is few, and volume is little.2. armature does not have iron core, has given up silicon steel sheet, and therefore in light weight, inertia is little, and time constant can reach the 15-20 millisecond.3. noise is low, and commutation ability is good, and spark is little, and brush life is long.4. armature resistance is little, operates steadily, and torsion is big, speed-regulating range width.5. simple in structure, easy to manufacture, materials are few, and technology is simple, and cost is low.
Description of drawings:
Fig. 1 is the structure cutaway view of the two-sided motor of the utility model;
Fig. 2 is that Figure 1B-B is to cutaway view;
Fig. 3 is that Figure 1A-A is to cutaway view;
Fig. 4 is the structure cutaway view of the utility model single face motor.
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:
Rotor of the present utility model is made of motor shaft 5, the commutator 7 and the rotor plate rail 8 that are packed on the motor shaft.Be fixed with coil holder 4 on the rotor plate rail, be wound with winding 3 on the coil holder.Winding is the fan type, and is distributed on the rotor plate rail.The rotor plate rail can be key with motor shaft and is connected also and can be made by sheet metal.Winding can also can be two-sided (as Fig. 1) of rotor disk frame in the single face (see figure 4) of rotor plate rail.Stator of the present utility model is made of upper casing 1 and lower casing 9.Uniform being shaped in ring-type deep trouth and its is fixed with magnet steel 2 on upper casing and the lower casing inwall, and magnet steel also is the fan type and distributes, and magnet steel is a Fe-B rare-earth permanent magnet.Brush 6 is packed on the upper casing.Casing is by making such as metal material such as iron, stainless steel, aluminium.
Operation principle of the present utility model is:
The fan type Fe-B rare-earth permanent magnet magnet steel that adopting goes in ring arranges is as stator, set up the belt magnetic confining field in plane with the rotor of dish type winding, thereby make rotor cutting magnetic field effective area reach maximum, the moment of torsion maximum, the armature that rotor disk is configured to is in light weight, and inertia is little, and noise is low, torsion is big, speed-regulating range width.This motor volume is little, the efficient height, and the scope of application is wide.
