1. Product Overview
Step motor is a motor that converts the electrical pulse signal
into the corresponding angle displacement or the line displacement.
It can use the quantity and frequency of the pulse to control the
rotation (rotation angle, rotation speed) in automation
applications. For each of the pulse, the motor rotor rotates a
angle or forward, and its output angle shift or line displacement
is proportional to the input pulse, and the speed is proportional
to the pulse frequency. Therefore, step motor is also called pulse
motor.
In the case of non-overload, the speed of the motor and the stop
position depends only on the frequency and number of the pulsed
input, without being affected by the load change. That is to say,
add a pulse signal to the motor, and the motor turns a step
distance. The advantage of this linear relationship between pulse
and angle rotation, plus that a step motor only has periodic errors
without cumulative errors, make step motor widely used in
automation speed, position and other control fields easily.
With the development of product research and development of
technology, the performance of the step system has been even more
improved. If the stepper system is not overloaded, there will be no
step loss mostly nowadays, and life time very long, almost no need
maintenance, which makes steppers popular and widely used in many
kinds of industrial automation motion control applications.
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.
