gearboxes and geared motors, you should always consider certain key design
aspects in accordance with the intended motion control application.
The first step should
always be a studious examination of the relevant technical and commercial
requirements of your application and the gearbox or geared-motor unit you wish
to use with it. This information will help you identify the ideal motor for the
intended application, and is also crucial when custom-designing a gear motor
and building it from scratch.
should use an application checklist when deciding on the motor specifications
you will need. These details along with project specific elements will determine
the course of the gear motor design or selection process.
Gear Motor Design and Motion Control Applications
control application will have its own individual characteristics, so early on
in the design or selection process you must determine which particular
parameters are the most important for the intended application. It might be horsepower,
lifespan, noise and vibration levels, or something like the starting torque ratio.
The speed and
torque of the application are usually going to be important elements in most
applications. It may be that the application requires a gearbox with a separate
motor, or possibly a single geared-motor unit is the ideal driving component.
Separate Gearbox and Motor or Combined Gear Motor?
gearboxes can often be mixed and matched according to the requirements of the
application, though sometimes a complete gear motor might be the best solution.
The types of
motors and gearbox designs that can be combined together include the likes of planetary
and parallel shaft gearboxes which can be combined with either permanent magnet
DC motors or AC induction motors. Getting
the blend right is crucial as certain combinations of gearboxes and motors will
be more efficient, produce higher performances and be more cost-effective than
geared-motor unit can be the easiest option for many applications as you have
the option of buying a pre-engineered gear motor that will save you time.
Examine Gear Motor Design Limitations
Once you have
identified potential gearboxes and motors or a
combined gear motor for your applications, it is necessary to review the limitations
inherent in the design. Examine aspects such as the gear motor’s thermal
characteristics, the gearbox input speed and yield strength, as well as the gearbox
torque when fully loaded.
Perform Test Runs with the Selected Geared-Motor Unit
Ideally you will
have the opportunity to perform test runs that will reflect typical operating
scenarios the gear motor will operate in. Look out for issues such as weird
noises, excessive heat emanating from the motor, or any other obvious signs of motor
stress. Without the test process you can never really be sure if the chosen
gear motor will definitely perform well under the conditions it is expected to.
The problems an unsuitable motor encounters can ultimately damage the motion
control application itself.
Remember that the
geared-motor unit selection process is as important as it can be arduous, but
by following these steps you can ensure your gear motor has a long life with a
consistently optimal performance level.
