Finding or designing the correct gear motor for your project or job can seem like a daunting task but it really is not as hard as it seems. Gear motors are highly customizable and relatively simple to use and work with so you may end up pleasantly surprised and attempt to put gear motors in everything you design. For some great, practical tips on how to choose the right geared motor for you and how to work with it, look no further because you have found it here.
Where To Start
The first thing you want to do when selecting a gear motor is to figure out your needs. Find out what the motor needs to accomplish. Make a list of everything you need it to do and then prioritize those items. The best way to prioritize the needed factors is to organize them based on what is the most important factor for making the system function well down to items that are more of a preference but not necessary.
An example of this would be to put the need to lift extremely heavy objects at the top of your list and the need to be a certain size near the middle of your list and then at the bottom of the priority list would be your preference in noise or heat.
The following qualifications are a good way to start ranking the needs of your gear motor as mentioned above. Use these factors to decide what exactly your project needs. If you or the manufacturer do not know exactly what you need, it is impossible to find or design the correct gear motor.
- Source Of Power – This is a pretty important qualifier because it determines what type of power you are able to use to move this device. You will want to know the max current in amps, frequency in Hz, voltage and possibly even the control type. All of these are factors in what kind of motor you can use.
- Environment Of System – Knowing what kind of environment the motor should work in is important because it will change based on the temperature and possibly even the humidity. For some, this will be more in the preference range and for others it will be a necessity especially working in delicate locations or harsh climates.
- System Specifications – This is where size comes in. Usually, there will be a very strong preference for size and weight of the gear motor based on what it is being used for. This is also where you figure out how much noise it can produce (or is able to be put up with in some cases) as well as how long it lasts and how often it needs to be inspected and/or maintained.
- Performance Of System – Torque is one of the biggest and most important factors of a gear motor. What needs to be known is the preference for starting and stopping torque ability as well as general speed allowance/generation. The performance also includes how long the motor is expected to be working and for what length of periods.
- Other System Preferences – Other important factors that go into this process include what type of lubrication is used, how it is installed or mounted, how big its container needs to be, etc.
Selecting A Gearbox & Motor
There are two main ways to go about the final step of selection. The first way is to find a geared motor like these that suits the needs of your device and the second way is to design your own by choosing separate gearbox and motor and then putting them together yourself (or having them assembled for you).
