Abstract
The utility model discloses a novel direct-current motor which comprises a rotor, a stator, a front cover and a rear cover, wherein the rotor comprises a rotating shaft, a punching sheet and a permanent magnet; the permanent magnet comprises a plurality of arced permanent magnet sub-pieces and is fixed on the outer side of the punching sheet in a surrounding manner. The novel direct-current motor is characterized by further comprising a frequency conversion circuit board and a circuit board cover; the frequency conversion circuit board is connected with a stator circuit; the circuit board cover is positioned on the outer side of the rear cover; the frequency conversion circuit board is installed on the circuit board cover; the punching sheet is fixed on the rotating shaft in a cylindrical circular manner; and a concave frame-shaped through hole is formed inside the punching sheet. As the concave frame-shaped through hole is formed inside the punching sheet, the high efficiency of the magnets with equal magnetic force is brought into play, the working efficiency of the motor is improved, the energy conversion rate of the motor provided by the utility model is more than 90%, the energy conservation effect is good, and the manufacturing cost is saved.
Description
Technical field
The utility model relates to a kind of technical field of motors, particularly a kind of direct current machine.
Background technology
Motor comprises rotor and stator two parts, and it is the conversion equipment of realizing electric energy and mechanical energy and mechanical energy and electric energy.Due to higher to the requirement of magnet performance in rotor, adopt general magnet can't satisfy the performance requirement of motor, so present motor generally adopt rare earth forever ndfeb magnet as the magnet on rotor.
Rare earth neodymium iron boron (NdFeB) forever is the strongest permanent magnet of contemporary magnet performance, it not only has the characteristics such as high remanent magnetism, high-coercive force, high energy product, high performance price ratio, and easily be processed into various sizes, Aeronautics and Astronautics, electronics, electroacoustic, electromechanics, instrument, instrument, packing, toy, medical skill now have been widely used in and other need with in the device and equipment of permanent magnetic field, be specially adapted to develop the various regeneration products of high-performance, miniaturization, lightness.But the main raw material(s) of producing ndfeb magnet has rare earth metal neodymium, rare earth metal praseodymium, pure iron, aluminium, ferro-boron and other rare earths materials, so the price comparison of ndfeb magnet is expensive, therefore causes production cost too high.
Summary of the invention
The utility model is for above the deficiencies in the prior art, provides that a kind of production cost is low, the New Type of Direct-current Machine of high efficiency.
The technical solution of the utility model is: a kind of New Type of Direct-current Machine, comprise rotor, stator, protecgulum, bonnet, rotor comprises rotating shaft, punching and permanent magnet, described permanent magnet is comprised of a plurality of arc-shaped permanent magnet piecemeals and around being fixed on the punching outside, it is characterized in that: also comprise frequency changer circuit plate and circuit board cover, described frequency changer circuit plate is connected with stator circuit, circuit board cover is positioned at outside bonnet, the frequency changer circuit plate is arranged on circuit board cover, it is cylindric around being fixed in rotating shaft that punching is, and is provided with the through hole of " recessed " font in punching.
The through hole of described " recessed " font is provided with 4-6 and evenly distribution.
Described punching is that the silicon steel sheet of 0.5mm builds up.
Described permanent magnet is ferrite lattice.
Described frequency changer circuit plate can be transformed into the 220V alternating current pulsation sine DC electricity of 300V, and after using this frequency changer circuit plate, the energy conversion rate of this motor can reach more than 90%, reaches energy-saving effect.
The beneficial effects of the utility model are:
The utility model is by increasing the frequency changer circuit plate, the 220V alternating current can be transformed into the pulsation sine DC electricity of 300V, electric energy conversion rate than conventional motors 30% left and right is, simultaneously by the through hole of " recessed " font is set in punching, the higher efficient of magnet performance that magnetic picture is worked as, improve the operating efficiency of motor, the motor energy conversion rate that the utility model provides reaches more than 90%, good energy-conserving effect.
Description of drawings
Fig. 1 is the structural representation of Novel DC described in the utility model.
The 1-stator, 2-rotor, 21-punching, 22-through hole, 23-permanent magnet, 3-protecgulum, 4-bonnet, 41-securing member, 5-circuit board cover, 6-frequency changer circuit plate, 7-rotating shaft.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1; a kind of New Type of Direct-current Machine, permanent magnet 23 are comprised of a plurality of arc-shaped permanent magnet 23 piecemeals and around being fixed on punching 21 outsides, in the utility model; permanent magnet 23 is ferrite lattice; ferrite stability is very good, and itself is oxide, and is very stable; be not easy oxidation; therefore do not need to do coating protection, and ferritic price is cheap more a lot of than ndfeb magnet, has saved manufacturing cost.
Frequency changer circuit plate 6 is connected with stator 1 circuit, and frequency changer circuit plate 6 can be transformed into the 220V alternating current pulsation sine DC electricity of 300V, and after using this frequency changer circuit plate 6, the energy conversion rate of this motor can reach more than 90%, reaches energy-saving effect.
Above demonstration and described principal character of the present utility model and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
