Hybrid Stepper Motor
Two-phase hybrid stepping motor is a hybrid motor. Two-phase hybrid stepping motor consists of stator and rotor. The common stator has eight poles or four poles, and a certain number of small teeth are evenly distributed on the pole surface; the coil on the pole can be electrified in two directions. Its rotor is also composed of two pieces of teeth with a certain number of small teeth on the circumference. The two teeth are staggered by half a pitch. A ring permanent magnet with axial magnetization is clamped between the two teeth. Obviously, all teeth on the same rotor blade have the same polarity, while the polarity of two different rotor blades is opposite.
Introduction of Hybrid Stepper Motor
Hybrid stepping motor is composed of stator and rotor. The common stator has 8 or 4 poles, and a certain number of teeth are evenly distributed on the polar surface. The upper pole coil can be energized in two directions, forming A phase and universal phase, B phase and B phase. Its rotor is also composed of two pieces of teeth evenly distributed on the circumference of a certain number of small teeth. The two tooth plates are staggered by half a tooth spacing. A ring of axially magnetized permanent magnetic steel is sandwiched between the two tooth plates. Obviously, all the teeth on the same rotor segment have the same polarity, while the two rotor segments have the opposite polarity. The structure diagram of the hybrid stepping motor is shown in FIG. 3-l. FIG. 3-2 is the profile model of the four-phase hybrid stepping motor with circumferential expansion. The figure above is the profile of the rotor S pole, and the figure below is the profile of the N pole. In the figure, the stator pitch and rotor pitch are the same. So let's think about the magnetic fields under poles I and IB. After the stator coil is energized, the magnetic pole I generates the N pole and the magnetic pole m generates the S pole.
