Rushan Trade Technical Secondary School, Rushan 264500, China) Abstract: The paper refers to a novel permanent magnet motor with composite-rotor, to solve the difficulties of extend speed by “flux weakening”. The rotor is composed of two rotor segments: one is made of AlNiCo magnet and the other of NdFeB. Relying on high coercive force and high remnant magnetic flux density quality of NdFeB, permanent magnet motor could get enough air gap magnetic fields. On the other way, by making using of low coercive force characteristics of AlNiCo magnet, the permanent motor could be changed the orientation and strength of magnetization when applying a pulse of magnetizing (demagnetizing) current, thus magnetic flux in air gap could be varied over wide range. To achieve the aim, the paper analyzes magnetization process of permanent magnet and transient magnetic circuit in the motor, and then computes the distribution of air gap magnetic field in different magnetization by using finite element method. The numeral results show the validity of the scheme. Key words: hysteretic magnetization model; flux weakening; composite-rotor; finite element method The cross-sectional view of a four-pole memory 1 Introduction Permanent magnet synchronous motors (PMSM) motor is shown in Fig.1. The rotor is built as a are now widely used in various industrial fields because sandwich of permanent magnet, soft iron and triangular of their high reliability and simple structure. It also has nonmagnetic material, all of them being mechanically other advantages such as high efficiency and power fixed to a nonmagnetic shaft. After applying a pulse of [1,2]factor. But if PMSM operates at high speed, the in opposite direction, the magnets are partially id output power is always decreasing sharply with speed demagnetized. One of the distinguish advantage is that increasing. This shortcoming influences the spread and the air-gap flux can be continuously varied within a application of the PMSM. fraction of period of stator current of the memory motor Obviously, if a conventional PMSM operates in with dissipating negligible losses, the other is that the [3]wide speed，vector control strategy is always adopted. load current i cannot demagnetize the magnet because q By controlling d-axis demagnetizing motive force i cannot go through magnet. q[4,5]excited by i, air-gap PM-flux can be weakened. To d maintain the balance of terminal voltage and adjust speed in the flux-weakening operation, d-axis inductance is always expected to be large enough. But d-axis large reluctance and small inductance of PMSMs limit the capability of flux-weakening and the range of speed. In the flux-weakening operation, total stator current is limited, so i reduces when i increases, and qd Fig. 1 Cross-sectional view of a variable-flux electromagnetic torque decreases much. At the same memory motor time, the i creates large stator copper loss. d 第五届国际炼铁科技大会 (ICSTI’09) The magnetization direction should be large enough in In order to improve mechanical strength and easy order to gain sufficient air-gap flux, and that is difficult for machining, the two rotor segments are both in tangential rotor magnetic circuit.

In addition, the PMSM needs usually motor high enough air- gap flux in the area of constant torque In this paper, the fundamental equations for with low speed while low much air-gap flux in the area magnetic field are represented in two-dimensional [9] of constant power with high speed.

Due to distinct difference of magnetization calculate the leakage flux coefficient with different character between AlNiCo and NdFeB, their responds shapes and different sizes of the stator pole boot of the (a) to the demagnetizing current are also different. The demagnetization curve of the two materials is shown in Fig.2 (a), (b), respectively. In Fig.2 (a), the remnant magnetic flux density of AlNiCo is much high, but the coercive force is very low. While in the Fig.2 (b), the remnant magnetic flux density and coercive force of NdFeB are both very high. More fortunately, the demagnetization curve is line that is identical to recoil curve. These characters make the magnetization (b) performance of NdFeB steady. In other words, if the demagnetizing magnetic field strength supplying to NdFeB is not larger than coercive force, the NdFeB material will not be demagnetized. So NdFeB could provide high enough air-gap flux in the low speed area, while AlNiCo could be used to adjust the air-gap flux through supplying i pulse to AlNiCo. Thus in the paper d the two permanent magnet materials form two rotor segments whose axial structure is shown in Fig.3, (a) De-magnetization curve of AlNiCo magnet; where 1-shaft, 2-bearing, 3-end shield, 4-stator (b) De-magnetization curve of NdFeB magnet winding, 5-frame, 6-stator iron core, 7-rotor iron core, 8-AlNiCo, 9-rotor iron core, 10-NdFeB.
