Two phase PM claw type stepping motor magnetic circuit made by rotor pole N pole, not back to the adjacent S pole, but due to the structure of the magnetic circuit itself, through the stator tooth, and generated by the stator, the stator tooth to return to the S pole, again by internal magnetic snap back to the N pole. The flux path as shown in figure the dotted line. This structure because of its round to form the magnet rotor internal mostly hollow, so can make low rotor inertia. This kind of step motor type and HB stepping motor are as follows: 1, the structure, the rotor flux is close to sine wave distribution, namely the rotor has no teeth, so the air gap flux distribution is close to sine wave, which can reduce vibration and noise, improve the accuracy of interval Angle. 2, the figure that, with the stator of the area of the rotor pole is about twice that of HB type rotor increased cross-linking magnetic flux. HB type rotor surface tooth slot relation is only 50%, and the difference between before and after the rotor teeth 1/2 pitch, and the RM type rotor surface 100% through effective magnetic flux. 3, is utilized to axial magnetic circuit formed by the three dimensional magnetic circuit, and the laminated stator core is very thick, magnetic flux to vertically stacked film through the core and the RM type stepping motor rotor magnetic circuit output axis is perpendicular to the plane of the circulation, the stator magnetic circuit formed along the direction of silicon steel rolling, so the shorter magnetic circuit, the magnetic resistance decreases. 4, the RM type rotor surface for not HB type of soft magnetic materials, so there is no small magnetic resistance, inductance, suitable for high speed running. See from the above analysis, the machine is suitable for high speed, high output power, low vibration, low noise. Compared with HB type, because of the limitation of magnetic pole number, difficult to achieve high resolution (Small step Angle)So according to purpose to choose them. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
