High Torque Nema17 17HS4401 Hybrid Stepper Motor 40mm 1.7 A 4.2kg.cm For CNC Router
Nema17 Hybrid Stepper Motor 17HS4401 High Torque 4.2kg.cm 1.7A 40mm length for CNC router
Stepper motor is known by its property to convert a train of input pulses into a precisely defined increment in the shaft position.
This is a high quality motor that can be used for a long time without stuck.
It has a quite stable performance during work and will not loss step.
Low noise and big torque, this is a great choice if you need a stepper motor.
Stepper motor can be widely used for 3D printer, CNC engraving machine, etc.

4.Advantages of Hybrid Stepper Motor
The advantages of the Hybrid Stepper Motor are as follows:-
- 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.
