Application of stepper motors:
 
3D Printing - Hybrid stepper motors are widely used in 3D printers to provide the precise motion control needed for layer-by-layer material extrusion. Their ability to hold position during printing while providing adequate torque enables accurate 3D object production.
 
Industrial control - In industrial automation and CNC machines, 42mm hybrid steppers are used for precise positioning and motion control. They power spindle motors in CNC machines, move axes in automated lathes and drive parts through assembly lines.
 
Computer peripherals - Hybrid steppers move drive belts in computer printers, scanners and copiers. They provide the precision needed for high quality document scanning and printing. They are also used in optical drives for reading and writing CDs/DVDs.
 
Packaging machinery - 42mm hybrid steppers are found in form-fill-seal machines, labelling applicators, palletisers and other packaging equipment. They enable accuracy and repeatability in material handling, product orientation and high-speed labelling.
 
Textile machinery - In textile manufacturing systems, hybrid steppers are used for warp let-off and take-up functions in looms. They precisely control tensions on warp threads to ensure consistent fabric production.
 
Mechatronics - Hybrid stepper motors aid in the motion control of various mechatronic devices including robots, precision XY stages and automated guided vehicles. Their digital inputs simplify control integration.
 
In summary, 42mm hybrid steppers provide an ideal balance of precise control capabilities with sufficient torque for medium load applications. Their wide performance range, combined with advantages like digital control, longevity and low cost, make them well suited for automation systems requiring accuracy and repeatability in motion.
 
Notes about hybrid stepper motors:
 
Customers should follow the principle of “selecting stepper motors first, then select driver based on existing stepper motor”
It is best not to use the full-step driving mode to drive a hybrid stepping motor, and the vibration is bigger under full-step driving.
Hybrid stepper motor is more suitable for low-speed occasions. We suggest the speed does not exceed 1000 rpm (6666PPS at 0.9 degrees), preferably between 1000-3000PPS (0.9 degrees), and it can be attached with a gearbox to lower it’s speed. The motor has high working efficiency and low noise at suitable frequency.
Due to historical reasons, only the motor with a nominal 12V voltage uses 12V. Other rated voltage on design drawing is not exactly the most suitable driving voltage for the motor. Customers should choose suitable driving voltage and suitable driver based on own requirement.
When the motor is used with high speed or large load, it generally does not start at the working speed directly. We suggest to gradually increases the frequency and speed. For two reasons: First, the motor does not lose steps, and second, it can reduce noise and improve the positioning accuracy.
The motor should not work in the vibration area(below 600 PPS ). If it must be used at slow speed, vibration problem could be reduced by changing the voltage, current or adding some damping.
When the motor works below 600PPS (0.9 degrees), it should be driven by small current, large inductance and low voltage.
For loads with a large moment of inertia, a large size motor should be selected.
When higher precision is required, it could be solved by adding gearbox, increasing the motor speed, or using subdivision driving. Also a 5-phase motor(unipolar motor) could be used, but the price of the entire system is relatively expensive, so it’s rarely used.
 
 
Advantage of stepper motors:
Stepper motor can reach precise control even without close-loop encoders / without feed back system, also they do not have electrical brushed. Thus there is no electromagnetic interference and electrical sparks issues. In some cases, they can replace DC brushed motors/ brushless motors.
Stepper motors are easy to control with drivers, and this feature establish its important position in the field of precise control.
1. Precise control achievable, programmable
2. Without electromagnetic interference & electrical sparks
3. Small size
4. Reasonable price
5. Low noise
6. Long service life
