Description
Technical Field
The invention relates to the field of rotating motors, in particular to an adjustable magnetic rotating motor.
Background
The permanent magnet motor is widely applied to the electric automobile with the advantages of high efficiency, high torque density, high reliability and the like, but the electric automobile has high requirements on the power output performance of the driving motor in a wider range from a low rotation speed area to a high rotation speed area, and low-speed high torque output is required at low speed so as to meet the starting of the whole automobile, such as acceleration and climbing; constant power is required to be maintained at high speeds to meet the maximum vehicle speed requirements of the whole vehicle, and overtaking at high speeds. The magnetic field of the permanent magnet motor is difficult to adjust, and although the permanent magnet field can be adjusted through weak magnetism, the weak magnetism is still insufficient to support a large rotating speed operation range required by an electric automobile on one hand, and copper loss of a stator winding is greatly increased due to the existence of a direct axis component of stator current, so that the efficiency of the permanent magnet motor is reduced. On the other hand, in the process of weak magnetic speed expansion, more or less demagnetization of the permanent magnet steel inevitably occurs, and the reliability of the permanent magnet motor is reduced. It can be seen that it is substantially difficult for conventional permanent magnet motors to meet the performance requirements of the entire area.

Detailed Description
The invention is further described below with reference to the accompanying drawings:
as shown in fig. 1 to 4, the adjustable magnetic rotating motor provided by the invention comprises a casing 4, a stator core 6, a rotor core 7 and a rotating shaft 1; the stator core 6 is fixed on the shell 4; the stator winding 5 is embedded in the stator core 6; the rotor core 7 is internally provided with a plurality of tangential permanent magnet steels 9, and N levels and S levels of the tangential permanent magnet steels 9 are alternately arranged; one end of the rotor core 7 in the axial direction is connected with the rotating shaft 1, and a space is arranged between the other end of the rotor core and the rotating shaft 1; a magnetically modulated ring 8 which can axially rotate and move is arranged in the space.
One end of the rotating shaft 1 is supported on the first end cover 3-1 through a first bearing 2-1, and the other end of the rotating shaft is supported on the second end cover 3-2 through a second bearing 2-2; the first end cap 3-1 and the second end cap 3-2 are fixed to the casing 4.
The stator core 6 is fixed to the housing 4 by shrink-fitting, cold-pressing or other means. Preferably, a hot jacket mode is adopted.
The magnetic adjusting ring 8 is connected with the rotating shaft through a spiral spline and can rotate and move on the rotating shaft.
The gap between the stator core 6 and the rotor core 7 is a permanent magnet motor main air gap, which is also called a first air gap, and the radial length of the first air gap is delta 1 The unit is mm. A first salient pole 10 extends inwards from the center of the magnetic pole of the rotor core 7, and a second salient pole 11 extends outwards from the outer wall of the magnetic modulation ring 8; the gap between the first salient pole 10 and the second salient pole 11 is a second air gap, and the radial length of the second air gap is delta 2 The unit is mm; when the first salient poles 10 and the second salient poles 11 are in one-to-one correspondence, delta 2 Less than delta 1 。
The working principle of the motor is as follows:
as shown in fig. 3, when the rotating electrical machine is running at low speed, a larger output torque is required, at this time, the distance between the second salient pole 11 on the magnetic modulation ring 8 and the first salient pole 10 of the rotor core 7 is farthest, the magnetic flux closed by the magnetic modulation ring 8 is very small, almost all the permanent magnetic flux passes through the main air gap of the machine, torque output is provided to the outside, and the magnetic flux path of the permanent magnetic steel 9 is: the magnetic flux starts from the N pole of the permanent magnet steel 9 and returns to the S pole of the permanent magnet steel 9 through the rotor core 7, the main motor air gap, the stator core 6, the main motor air gap and the rotor core 7 to form a closed loop.
As shown in fig. 4, when the rotating motor is operated to a high-speed working condition and needs weak magnetism, the magnetism regulating ring 8 moves axially into the space between the rotor core 7 and the rotating shaft 1 under the action of external force, and simultaneously rotates by a certain angle according to the set spiral spline to enable the second salient pole 11 and the rotor on the magnetism regulating ring 8 at the momentThe first salient poles 10 of the iron core are in one-to-one correspondence (one-to-one correspondence, i.e., the outer end surfaces of the two salient poles are oppositely arranged in fig. 4), due to delta 2 Less than delta 1 According to the principle of 'magnetic resistance minimum', most of the permanent magnetic flux generated by the permanent magnetic steel 9 starts from the N pole of the permanent magnetic steel 9, and a closed loop is formed by the first salient pole 10 of the rotor core, the second air gap, the magnetic regulating ring 8, the second air gap, the first salient pole 10 of the rotor core and the S pole at the inner side of the permanent magnetic steel 9. The part of permanent magnetic flux does not pass through the first air gap, does not provide torque output to the outside, and belongs to ineffective magnetic flux.
At present, the permanent magnetic field of the rotating motor is basically constant, and the size and the direction of the magnetic field are not well regulated. The effective magnetic flux passing through the first air gap is regulated through the rotary movement of the magnetic regulating ring 8, the structure is simple and compact, the weak magnetic expansion can be effectively carried out, and the device is very suitable for occasions with low-speed large torque and high rotating speed operation.
It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
