20mm Encoder Stepper Motor 1.8degree Nema8 Hybrid Stepping Motor for 3d printer

• What is stepper motor?
• Stepper motor is an actuator transforming electric pulse into angular displacement. Popularly, when receiving a pulse signal, the stepper motor will rotate a fixed angle (namely ''stepping angle'') according to the direction set for the stepper motor. The angular displacement volume can be controlled by controlling the pulse number to achieve the purpose of positioning accurately. In the meantime, the rotational velocity and acceleration of motor can be controlled by controlling the pulse frequency to achieve the purpose of speed control.

Description of NEMA8 hybrid stepper motor

1. Online testing of technical parameters to ensure the consistency of data product parameters

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

3. Automatic assembly line

Automatic assembly line, improve production efficiency, low cost without human operation, one line down intelligent mechanical automatic assembly

4. Accurate position Control

The angular displacement of the stepping motor can be precise controlled by the number of electrical pulses.Angle accuracy can be controlled within ±0.09°without any feedback devices.

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.

Applications of Stepper Motors

Stepper motors are diverse in their uses, but some of the most common include:

• 3D printing equipment
• Textile machines
• Printing presses
• Gaming machines
• Medical imaging machinery
• Small robotics
• CNC milling machines
• Welding equipment

0.9° and 1.8° Hybrid Stepper Motors

1.8° Step Angle,The motors are directly compatible with the stepper motor drive boards and also drive either motor (if required) in the half step mode i.e. 0.9° per step resulting in higher resolution, greater performance stability and faster stepping rates. Direction, velocity, acceleration/deceleration can be controlled by a stepper motor controller.,Applying the correct electrical pulse sequence to the windings of the stepper motor results in a 1.8° step angle rotation of the spindle (i.e. 200 steps per revolution). When correctly loaded and driven these motors will produce discrete output steps. The number of steps and speed of rotation are determined by the number of pulses and frequency of the input signal. This provides an ideal method for speed and position control. The motors are directly compatible with stepper motor drive boards.
