0.9° Nema17 2phase Hybrid Stepper Motor 42mm Stepping Motor For 3D Printer
1.Brief Introduction
- 42HS series hybrid stepper motors are supplied by one of the China's top stepper motor suppliers (JKONGMOTOR). These NEMA 17 square stepper motor with 0.9° step angle (400 steps/revolution) are made of high-quality material. The body length of NEMA 17 stepper motors ranges from 34mm to 60mm, and the holding torque could be as high as 5.5kg.cm . These high-performance and high-reliability NEMA 17 stepper motors are terminated with four or six lead wires, and could be easily connected to the constant current or chopper drive controllers.
- The 42mm Hybrid Stepper Motor Series is a versatile family of motors suitable for a wide range of applications. Use with a microstepping driver to reduce vibration and achieve higher step resolution. Choose a baseline version or request your own customized configuration.
- Features:
- Bipolar or unipolar versions available
- Hybrid stepper construction
- Available in single or double shaft versions
- CE and RoHS approved

Stepper Motor Advantages
- Low cost for control achieved
- High torque at startup and low speeds
- Ruggedness
- Simplicity of construction
- Can operate in an open loop control system
- Low maintenance
- Less likely to stall or slip
- Will work in any environment
- Can be used in robotics in a wide scale.
- High reliability
- The rotation angle of the motor is proportional to the input pulse.
- The motor has full torque at standstill (if the windings are energized)
- Precise positioning and repeatability of movement since good stepper motors have an accuracy of 3–5% of a step and this error is non-cumulative from one step to the next.
- Excellent response to starting/stopping/reversing.
- Very reliable since there are no contact brushes in the motor. Therefore, the life of the motor is simply dependent on the life of the bearing.
- The motors response to digital input pulses provides open-loop control, making the motor simpler and less costly to control.
- It is possible to achieve very low-speed synchronous rotation with a load that is directly coupled to the shaft.
- A wide range of rotational speeds can be realized as the speed is proportional to the frequency of the input pulses.
Applications
As the stepper motor are digitally controlled using an input pulse, they are suitable for use with computer controlled systems.
They are used in numeric control of machine tools.
Used in tape drives, floppy disc drives, printers and electric watches.
The stepper motor also use in X-Y plotter and robotics.
It has wide application in textile industries and integrated circuit fabrications.
The other applications of the Stepper Motor are in spacecrafts launched for scientific explorations of the planets etc.
These motors also find a variety of commercial, medical and military applications and also used in the production of science fiction movies.
Stepper motors of microwatts are used in the wrist watches.
In the machine tool, the stepper motors with ratings of several tens of kilowatts is used.
