Application of stepper motors:
Stepper motors are used for precise control, widely used on medical
equipment, 3D printer, industrial precise control, automation
equipment, etc.
Stepper motors can be used in any mechanisms requirement precise
conrtol and rotational/linear movement.
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
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.
