■ OPERATING PRINCIPLES
The operating explanation is as follows.
When an electric current is passed through the rotor
through the commutator, because it is in the magnetic field,
it rotates. This rotational force is used to perform
mechanical work.

■ GLOSSARY
●Momentary maximum current
The maximum current that can be tolerated for one second
without demagnetizing the magnets or causing other
damage.
●Torque constant
The torque generated by the motor when a current of 1 A is
applied.

APPLICATIONS

HANDLING NOTES
● Avoid press fitting components to the output
shaft.
● When using pulse drive in the operating mode,
be careful to avoid applying unnecessary shock
loads to the gears.
● Do not attempt to modify or disassemble the DC
geared motors. In particular, pinholing or cutting
the shaft will result in degraded performance
and should be absolutely avoided.

DCｷﾞﾔｰﾄﾞﾓｰﾀ 取付方法
● Increasing the reduction ratio produces
increased torque, but there are limits to the
strength of the material, so if the starting torque
for the geared motor exceeds the guaranteed
strength, avoid locking the output shaft.
● When using belts or cams to transmit the torque
from the output shaft, problems can occur to the
PV value of the gear shaft material drastically
reducing the life, so due care is required.
● Avoid press fitting components to the output
shaft.
