HB type stepping motor has two phase, three-phase, five phase type, the rotor for has nothing to do with the number of phase, and the same rotor, this section with two phase HB stepping motor as an example to illustrate. HB type the name of the derived from the rotor structure, the rotor is PM a complex type with VR type rotor, is widely used in Japan. Rotor structure between two magnetic disk with a permanent magnet cylinder axial string together, two magnetic disk cylindrical gear pitch is the same, same as the aforementioned VR type rotor structure, its two 1/2 pitch to install the disc of tooth stagger, cylindrical permanent magnet rotor axial magnetization for N pole at one end and the other end for the S pole. In front of the motor rotor and the narration of PM rotor from the point of structure, type PM rotor N pole and S pole distribution on external surface of the rotor, to increase the resolution, increase of logarithmic, usually 20 mm in diameter, the rotor can be configured for 24, such as the number of add, will increase the magnetic flux leakage, reduce electromagnetic torque; And HB type rotor N pole and S pole distribution on two different soft magnetic disc, so can increase the number of rotor, thereby improving resolution, 100, 20 mm diameter can be configured and axial of poles magnetization, N pole and S pole after assembling the poles magnetization, the magnetization simple so. With the corresponding stator rotor teeth, main pole diameter is the same as the rotor tooth pitch of small teeth, and the rotor tooth flux in the air gap interaction, can produce electromagnetic torque. The rotor of stepper motor is widely used in the near future. 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.
