12V 4phase 0.4A 12kg.cm PMG35 Series Geared Stepper Motor
motores paso a pas
1.Brief Introduction of stepper motor:
This newly developed geared motor uses a molded planetary gearbox.
Large reduction ratios can be realized in a compact size, along
with high output and high resolution. The controllability that
characterizes our PM motors has also been maintained, allowing for
simplification of the system structure and easy handling.
The geared stepper motor is a combination of stepper motor and
gearbox. As we know, the brushed DC motor will keep rotating if
connected to a DC power supply. Things are different for geared
stepper motor. It will convert the input pulse into a precisely
defined increment in the shaft position. The shaft is moved by each
pulse with a fixed angle. That means every pulse inputs, the
rotator will move a step or rotate at a fixed angle. The rotating
speed is proportional to the pulse frequency. Therefore, you can
control the rotating speed by changing the frequency of the input
pulse, realizing precise positioning.
Working Principle
This product is an open-loop control system that converts pulse
signal into angular or linear displacement. The amount of
displacement can be controlled by adjusting the number of pulses,
so accurate positioning can be achieved.
Features
High torque, fast dynamic response, low noise, low cost
Drive Mode
Unipolar or bipolar, constant voltage drive

5.Common Problems and Solutions of PM Stepper Gear Motor:
Out-of-step caused by insufficient torque and failure of oiling
bearing may occur. These can be solved by increasing the torque of
the motor and using ball bearing. Our after-sale personnel will ask
customers about the use of the products irregularly. According to
the feedback from the customers, we will conscientiously sum up,
learning from the successful experience and correcting the
deficiencies.
6.Application of PM Step motor with Gear Box:
Permanent magnet stepper motors use a permanent magnet (PM) in the
rotor and operate on the attraction or repulsion between the rotor
PM and the stator electromagnets. Permanent magnet stepping motors
are generally two-phase, with small torque and volume, and the step
angle is generally 3.75 degrees, 7.5 degrees, 15 degrees or 18
degrees, etc. MOONS' PM stepper motors are widely applied in many
innovative applications, including: computer equipment,
photographic systems, optoelectronic devices, valve control, ATM
equipment, CNC machine, automatic winding machines, electronic
clocks and medical equipment.
