Application
The working life of the gear motor generally exceeds the working
life of the DC motor, which can usually reach 1000 to 3000 hours.
The total reduction ratio of the gearbox is generally in the range
of 1:10 to 1:500. After special design, it can reach 1:1000 or
larger, but the gearbox with a large reduction ratio is not allowed
to "reverse", that is, it cannot use the output shaft of the gear
motor as the drive shaft to force reverse.
Due to the limitation of gear strength, when the total transmission
is large, the gear motor may not be able to withstand the
locked-rotor torque, and the load torque at this time cannot exceed
the maximum allowable short-time load torque.
The gear motor consists of multiple gear pairs. Each stage includes
a pair of meshing gears consisting of a sheet gear and a pinion.
The first pinion is mounted on the output shaft of the motor. The
bearing used for the output shaft of the gear box is usually an oil
bearing made of sintered copper or iron material.
Motors can be constructed in several different physical
configurations. In the conventional (also known as inrunner)
configuration, the permanent magnets are part of the radially
center core. In the outrunner (or external-rotor) configuration,
the radial-relationship between the coils and magnets is reversed.
The stator coils in the outrunner configuration form the center
core of the motor, while the permanent magnets spin within an
overhanging rotor which surrounds the core.
Gear motors function as torque multipliers and speed reducers,
requiring less motor power to drive a given load. The gear housing
design, the gearing type, gear lubrication, and the specific mode
of integration all affect the gearmotor performance.
Increasing the reduction ratio producesincreased torque. but there
are limits to thestrength of the material, so if the starting
torquefor the geared motor exceeds the guaranteedstrength, avoid
locking the output shaft. When using belts or cams to transmit the
torquefrom the output shaft, problems can occur to thePV value of
the gear shaft material drasticallyreducing the life so due care is
requiredAvoid press fitting components to the outputshaft.
