Abstract
The utility model relates to a hidden pole permanent magnet rotor, higher speed single-phase capacity operation permanent magnetic motor, mainly comprising a hidden pole permanent magnet rotor, a stator, two bearings, a front end cover, a rear end cover and a plurality of screw bolts. The rear cover front and the rear end cover are arranged at both ends of the stator and connected as an integrated body through screw bolts. The front and the rear of the hidden pole permanent magnet rotor are respectively pivoted in the front end cover and the rear end cover through two bearings, and the place between the outer circumferential of the stator and the rotor is provided with an interval. The outer surface of the hidden pole permanent magnet rotor is in a cylinder shape and uniformly distributed with a plurality of field poles. Thus, because of the easy processing of the cylinder, the concentricity of the rotor can be raised. Therefore, the rotary motion of the motor is smoother.

Technical field
The utility model relates to the single-phase capacitor running permanent magnet motor of a kind of non-salient pole permanent magnet rotor, higher speed.
Background technology
At present, the synchronizing speed of the single-phase capacitor operation motor of general p-m rotor is lower, and when supply frequency 50HZ, the synchronizing speed of, a kind of permanent magnet motor is 250r/min as shown in Figure 5; The synchronizing speed of another kind of permanent magnet motor as shown in Figure 6 is 375r/min; The synchronizing speed of another low speed reaction equation permanent magnet motor as shown in Figure 7 is 60r/min; And the permanent magnet synchronous motor of general fair speed, its p-m rotor is again a salient pole type, as shown in Figure 8, in order to add large starting moment, needs to adopt flume structure on this salient pole type p-m rotor, makes difficulty.
Summary of the invention
The purpose of this utility model is to make the problem of difficulty for fear of the salient pole type p-m rotor, and provide the single-phase capacitor running permanent magnet motor of a kind of non-salient pole permanent magnet rotor, higher speed, mainly be with a kind of columniform p-m rotor, and magnetic pole is distributed on the cylindrical surface of this p-m rotor.
The technical solution adopted in the utility model: mainly be by a non-salient pole permanent magnet rotor, stator, two bearings, each forward and backward end cap, and a plurality of bolts and constituting, this forward and backward end cap is in the stator two ends, and connect in aggregates with bolt, this non-salient pole permanent magnet rotor is articulated in the forward and backward end cap so that two bearings is forward and backward respectively, and with the stator excircle separately, the outer surface of this non-salient pole permanent magnet rotor is a cylindrical shape, and a plurality of magnetic poles that evenly distribute on it.
Described non-salient pole permanent magnet rotor is to be solidly set on the rotating shaft excircle by the cylinder annular permanent magnet to constitute.
Described magnetic pole is 4 utmost points or 6 utmost points or 8 utmost points.
The utility model is because cylindrical handling ease can make the concentricity of rotor improve, and it is more steady that motor is rotated.
