Nema 11 28mm 1A 0.08N.M Nema Stepper Motor

Product Specification

NEMA11 Encoder stepper motor 2 phase hybrid 1.8 degree stepper motor

Tips: Which types of stepper motor is divided into?

Stepper motor is divided into three types: permanent magnet stepper motor (PM), variable reluctance stepper motor (VR) and hybrid stepper motor (HB).

• PM stepper motor is generally 2-phase, with small torque and volume, its stepping angle is generally 7.5° or 15°.
• VR stepper motor is generally 3-phase; high torque output can be realized; the stepping angle is generally 1.5, but the noise and vibration is large. The rotor magnetic circuit of VR stepper motor is made of soft magnetic materials. There is multi-phase exciting winding on the rotor. The torque is generated by taking advantage of the change in magnetic conductance.
• HB stepper motor, indicating mixing the advantages of PM and VR, is divided into 2-phase, 3-phase and 5-phase. The stepping angle of 2-phase is generally 1.8°, that of 3-phase 1.2° and that of 5-phase is 0.72°. It is mostly widely applied.

Product description of encoder stepper motor

1. Material quality: The coat is 304 stainless steel, the water jacket is the high compression casting aluminum tube, the red copper coil.

2. Forward/Reverse Rotation,Pause and Hold

   The forward /reverse rotation of the stepping motor can be controlled by the input sequence of the controlled electric pulses.

   In the case of the a stepping motor lock(the motor winding is energized,there is no external electric pulse command),the stepping motor can still maintain a certain torque output.

3. Strictly control the production of parts to improve the quality of parts

4. Automatic machine operation, stable automatic work, high processing efficiency.

   Mechanical size 100% meet the requirements, to ensure that there is no greater error in the use process

5. Longer Life

   Stepping motor is a mechanical structure,which does not need be changed by electric brush or Hall sensor,thus reducing the probability and increasing the motor life.Stepping motor life usually determined by the life of the bearing.

Encoder stepper motor Application

Computer controlled stepper motors are a type of motion-control positioning system. They are typically digitally controlled as part of an open loop system for use in holding or positioning applications.

In the field of lasers and optics they are frequently used in precision positioning equipment such as linear actuators, linear stages, rotation stages, goniometers, and mirror mounts. Other uses are in packaging machinery, and positioning of valve pilot stages for fluid control systems.

Commercially, stepper motors are used in floppy disk drives, flatbed scanners, computer printers, plotters, slot machines, image scanners, compact disc drives, intelligent lighting, camera lenses, CNC machines and, more recently, in 3D printers.

Advantage of Product

• Prostepper motor use of a unique stator the chnology to ensure that the motor stator teeth grinding and smooth high accuracy of the hole, the work of the process of speed stability is not lose step
• Prostepper motorcoil is made of 100% pure copper enameled wire , advanced winding threading process, copper wire is evenly arranged, good overall motor stability , the long time does not appear deformation and noise and so on.
• High quality motor steel, the load on the shaft can produce high torque the inertia ratio, and can eliminate, the system error due to the use of reduction gears
