1. Products Overview
Step motor is a motor that converts the electrical pulse signal
into the corresponding angle displacement. For each of the pulse
signal, the rotor rotates a certain angle accordingly, and the
speed is proportional to the input pulses’ frequency. Therefore,
step motor is also called pulse motor.
The biggest difference between step motor compared to other control
motors is that it receives digital control signals (pulses) and
converts into angle displacement accordingly. Enter a pulse signal
to get a specified position increment. Compared with the
traditional DC control system, such a so-called incremental
position control system, the stepper system complexity and cost are
significantly reduced. The angular displacement of the stepping
motor is strictly proportional to the number of input pulse, and it
is synchronized with the pulse in time. Therefore, by controlling
the pulse frequency and pulse quantity, the motor shaft speed, and
position can be controlled precisely too.
At the same time, Kaifull has solved many problems of traditional
stepper drivers buy the latest patented technologies. There are
many middle and high end customers globally, and they highly
appreciate our stepper motor and drives very much.
The step motor is a motion execution agency that converts the pulse
signal into corner displacement or line displacement. Taking the
most used hybrid stepping motor as an example, its main features
are as the followings.
High loading capacity. Its speed is not affected by the load size. Unlike ordinary
motors, the speed will decrease when the load is increased. The
speed and position of the step motor have strict requirements.
Convenient control. The step motor rotates in "step", and the digital characteristics
are obvious.
Simple structure. The traditional mechanical structure for speed and position
control are more complicated, and it is difficult to adjust. After
the adoption of step motor, the structure of the whole machine is
simpler. At the same time, no need special maintenance, and the
failure ratio is very low.
100% still stop, no shaking. Because the stepper motor does not depend on feedback such as
position, speed, etc., when the input pulse stops, the step motor
can be in an absolute stop. The servo motor cannot be absolutely
stopped, so the characteristic of the stepper motor is definitely
very popular in the need for high precision applications.
Low noise. By proper subdivision setting, the step motor runs very smooth and
the noise is small, which is especially suitable for noise
sensitive applications.
Of course, there are obvious disadvantages of the stepper motor,
such as high running temperature. Although it does not affect the
service life of the stepper motor, it is not suitable for heating
sensitive applications. However, with the implement of the step
drive control algorithm, the input current adjustment range is
getting larger and larger, which helps to reduce the motor heating
significantly.
Kaifull PRMCAS Hybrid Stepper Motors Applications
Machine tools and engraving machines
The application of stepper motors in machine tools is also very
common. In machine tools, stepper motors are used to control the
feed and tool retraction, thereby achieving precision and speed in
machining workpieces. It can achieve different processing effects,
high speed, and high efficiency.
Automation equipment
The application of stepper motors in automation equipment is also
very extensive. In automation equipment, stepper motors are used to
control the position and speed of various moving components,
thereby achieving automation control of the equipment. It can
achieve different control effects, such as high speed and high
stability.
Printing machines
Stepper motors are widely used in printers. In a printer, a stepper
motor is used to control the movement of the print head, thereby
achieving precise printing of text, images, and charts. It can
achieve different printing effects, such as high definition, high
speed, and high stability.
Automotive components
The application of stepper motors in automotive components is also
very common. In automotive components, stepper motors are used to
control the position and speed of car seats, rearview mirrors,
windows, and doors, thereby achieving automated control of
automotive components. It can achieve different control effects,
such as high speed and high reliability.
Optical equipment
In optical equipment, stepper motors are widely used in modulators,
fine-tuning, and other aspects. Because the action of stepper
motors is very slow and the stepper angle can be adjusted, they are
widely used in various optical positioning mechanisms, which can
provide higher stability and accuracy for optical equipment.
Medical devices
Stepper motors are widely used in medical devices, especially in
surgical instruments such as blades and cutters. The high-precision
positioning of stepper motors can significantly improve the
accuracy of surgery and make surgery safer. Stepper motors can also
be used in devices such as pacemakers and syringes.
Precision positioning applications
Stepper motors can complete precise positioning tasks through
quantitative motion and fixed step angles, which makes them widely
used in various precision positioning equipment, such as optical
equipment, textile equipment, computer embroidery machines, medical
equipment, automation equipment, etc. These equipment usually
require high-precision and stable positioning machinery, and
stepper motors are perfect for such tasks.
In summary, stepper motors can be widely used in various fields due
to their characteristics of quantitative motion and fixed stepper
angle, providing more precise and efficient driving force for
mechanical equipment to achieve higher production efficiency and
quality.
