Abstract
The utility model relates to a high-efficiency asynchronously-started permanent-magnetic synchronous motor which comprises a rotor and a stator. The stator is composed of a stator coil and a stator core; the rotor is composed of a shaft, a rotor pressing plate, a cylindrical rotor core and 2n pairs of permanent magnets, wherein n is an integer not less than 1; each pair of permanent magnets is spliced into a splay shape to form one stage and be uniformly inlaid in a magnetic steel groove of the rotor core, an opening is right aligned with the shaft, and polarities of every two adjacent pairs of permanent magnets are opposite. The high-efficiency asynchronously-started permanent-magnetic synchronous motor has the following benefits: the synchronous motor improves the arrangement of magnetic steel by changing the structure and size of the magnetic steel groove which is commonly used at present; as the above structure is adopted, the permanent magnets are nearer to the outer circle of the stator core; through detection of the above structure, the magnetic density is low due to that the permanent magnets are nearer to the outer circle of the stator core; therefore, the reliability of the permanent magnets in long-time running process is ensured, the starting current of a motor is reduced, the performance of the motor is improved, and the efficiency of the motor is increased as well.
Description
Technical field
The utility model relates to the synchronous motor field, especially a kind of permanent magnet synchronous motor of efficient asynchronous starting.
Background technology
In the prior art, asynchronous starting permanent magnet synchronous motor electric efficiency height, power factor (PF) height are by most of people's cognitions.But because its starting current is big, reliability is not high, complex manufacturing is difficult to realize large-scale production.Asynchronous starting permanent magnet synchronous motor stator structure described in the utility model is consistent with the phase asynchronous induction motor of routine, and difference is rotor portion.The starting current of asynchronous starting permanent magnet synchronous motor is big in the prior art, reliability is not high, and main cause is what the cast aluminium sliver 26S Proteasome Structure and Function of rotor and magnet structure and assembling form caused.
The asynchronous starting permanent magnet synchronous motor rotor structure form of present prior art and the problem of existence:
1, magnetic structure Fig. 1 and Fig. 2 of radial rotor: this structure permanent magnet consumption depends on the structure and the size of magnet steel grooved, when tending to cause permanent magnet magnetic to lead to designing requirement the cast aluminium sliver every the magnetic poor effect, cause the motor temperature back permanent magnet demagnetization that raises to have a strong impact on motor performance.
2, tangential rotor magnetic circuit structural Fig. 3 and Fig. 4: this structure often causes the less very difficult arrival design of electrical motor requirement under the certain situation of temperature rise of permanent magnet consumption.
3, mixed rotor magnetic circuit structural Fig. 5, this structural formula is above-mentioned 1, the combination of 2 two kind of magnetic structure, this structure combines the advantage of above-mentioned two kinds of magnetic structures, but the permanent magnet consumption is too big and the rotor complex process, causes the motor manufacturing cost to increase greatly and is not easy to form large-scale production.
The utility model content
The utility model will solve the shortcoming of above-mentioned prior art, and the permanent magnet synchronous motor of a kind of high efficiency, high-performance, low starting current, operational reliability height, production technology efficient asynchronous starting simple, with low cost is provided.
The utility model solves the technical scheme that its technical problem adopts: the permanent magnet synchronous motor of this efficient asynchronous starting, comprise rotor and stator, stator is made up of stator coil and stator core, described rotor is made up of permanent magnet axle, rotor pressing plate, columniform rotor core and 2n, and n is not less than 1 integer; Every pair of permanent magnet is combined into " eight " font formation one and extremely evenly is embedded in the magnet steel groove of rotor core, and opening is towards being right against axle, and the per two pairs of permanent magnet polarities that face mutually are opposite.
As preferably, described each permanent magnet is rectangular structure.
As preferably, described rotor core by silicon steel plate stacking after cast aluminium form, form the cast aluminium sliver behind the cast aluminium, the magnet steel groove depth is the 1/12-1/6 of rotor core external diameter.
The effect that the utility model is useful is: by structure that changes magnet steel groove commonly used at present and the layout that size has been improved magnet steel, this structure makes the cylindrical of the more close stator core of permanent magnet, through detecting this structure, because outside the more close stator core of permanent magnet, make the magnetic close little, guaranteed the reliability of permanent magnet in the long-play process, reduced motor starting current, improved motor properties, improved electric efficiency.
