Hybrid Stepper Motor Stator And Rotor
hybrid stepper motor is a stepping motor which is designed for the advantages of permanent magnet type and reactive type. it is divided into two phases, three phases and five phases, and the two-phase step angle is generally 1.8 degrees, the three-phase step angle is 1.2 degrees, and the five-phase step angle is 0.72 degrees.
体彩11选5开奖结果查询hybrid stepping motor rotor itself has a magnetic, so in the same stator electric flow generated torque than reactive stepper motor, and the interval angle is usually small, therefore, the economical nc machine tool generally need to use hybrid stepping motor driver. however, the hybrid rotor has a complex structure and a large inertia of rotor, and its fast speed is lower than the reaction step motor
the structure of the hybrid stepping motor and reactive stepping motor, reactive stepper motor stator and rotor structure are an organic whole, and hybrid motor stator and rotor were divided into two section, shown below in the pole surface, there are also small teeth.
the two sections of the stator are good and the winding is arranged. the two phase 4 pairs of pole motors are shown in the above, and the l, 3, 5 and 7 are the magnetic poles of a phase winding, 2, 4, 6 and 8 are the magnetic poles of b phase winding. each phase of the adjacent magnetic pole winding is reversed to generate the closed magnetic path shown in the above image of x and y in the view.
b is similar to phase a. the two sections of the rotor are staggered apart, and the middle is connected with a ring permanent magnet steel, which is the opposite of the tooth of the rotor. according to the same principle of the reactive motor, the motor can rotate counterclockwise or clockwise as long as the motor is energized according to the order of ababa or ababa.
it is evident that all the teeth on the same segment have the same polarity, while the rotor blades in two different segments have the opposite polarity. the biggest difference between the hybrid stepper motor and the reaction type stepper motor is that when magnetized permanent magnetic material is demagnetized, there will be oscillating points and demagnetization areas.

体彩11选5开奖结果查询advantages: can be divided into two phase, three-phase hybrid stepping motor and five phase: two phase stepper angle of 1.8 degrees commonly and five phase stepping angle of 0.72 degrees commonly, hybrid stepping motor as the increase of the number of phase (several) winding the power supply, the stepping angle decreases, and improve the precision and the most widely used stepper motor. hybrid stepper motor combines the advantages of reactive and permanent magnet stepper motors: the polar logarithm is equal to the number of rotors, and can vary widely according to the requirements. winding inductance
the rotor position is small and easy to achieve optimal operation control. the new permanent magnetic material with high magnetic energy can be used to improve the performance of the motor. rotor magnetic steel provides excitation; there was no significant oscillation in the entire operating area.
