2 Phase 1.8 Degree Nema8 20mm Stepper Motor for Medical Equipment

2 phase 1.8 degree Nema8 20mm Stepper Motor for medical equipment


1) Product Description and images


The stepper motor is made of high-quality cold-rolled steel sheets and high-temperature permanent magnets. It has the characteristics of low temperature rise and high reliability. Because it has good internal damping characteristics, it runs smoothly without obvious vibration area. It can meet the needs of different industries and different environments.
Determine the requirements for positioning accuracy and vibration of the stepping motor: determine whether to subdivide and how many subdivisions are required. The driver is selected according to the current, subdivision and supply voltage of the motor.

5) Product information and advantages
Hybrid stepping motor combines the advantages of reactive type and permanent magnet type. The stator is provided with multi-phase windings, the rotor is made of permanent magnet materials, and the rotor and stator are provided with multiple small teeth to improve the step torque accuracy. Its characteristics are large output torque, good dynamic performance and small step angle, but its structure is complex and its cost is relatively high. According to the winding on the stator, there are two-phase, three-phase and five equal series.
The most popular is the two-phase hybrid stepping motor, accounting for more than 97% of the market share. The reason is that it is cost-effective and has good effect when equipped with a subdivision driver. The basic step angle of the stepper motor is 1.8 ° / step. When equipped with a half step driver, the step angle of the stepper motor is reduced to 0.9 °. When equipped with a subdivision driver, the step angle can be subdivided to 256 times (0.007 ° / microstep).
It is recommended that the user select the hardware subdivision type driver when selecting the stepping motor driver, because the hardware subdivision can be used for accurate positioning, while the software subdivision can only reduce the vibration noise of the motor, and cannot be used for accurate positioning.
