Hello. I am designing a motor/gearbox set up in order to be used to lift a weight via a cable. I am new to this, so I am hoping to receive some help on selecting the best motor for my needs. The motor is required to spin at atleast 5000rpm at 6V. From what I have read about, the faster the rpm the lower the torque output by the motor. So in browsing the on this sight, I am not sure what is the best option. Can somebody help suggest a motor for my application?
Thanks!
How much weight do you plan to lift, and how would you go about it (pulley? If so, what is the radius?)
Hello all, I am new to the forum so sorry if I do anything wrong
I have a project in my class where we have to design and build a lift mechanism(sorry not really a robot) and my group and I are having trouble deciding on a motor. The specifications are
The system is to be driven by one electric motor powered by a total of 4 AA batteries
The motor selected must have a minimum rated output speed of 5000 rpm at 6V or lower.
During operation, there should be no user interaction with the system, except to activate and deactivate the motor. The load should not lower itself if power is cut from the motor.
So I have an idea of what I am looking for, but not sure what to get at a reasonable price, so I am looking for suggestions on products. Any help would be appreciated!
Its a 20 lb weight.
And we are planning on using the motor attached to a gearbox (which we need to design/build) to rotate an output shaft which will have a spool to collect the rope as the shaft rotates.
Basically we need to know what motor we should use before designing the gearbox, but we have never used electric motors before and don’t know where to start with the selection process.
Thanks!
You could pick something like this

Again, I think for a lifting project, the key aspect will be building a gearbox and some sort of pulley system such that you can use your motor to lift heavy objects. You mentioned a minimum of 5000 rpm which means you can go with a motor that already has a gearbox since it may exceed a rated value of 5000 rpm.
If you plan on building a gearbox, pick a reputable DC brushed motor and build a gearbox around it.
This means that your gearbox needs to have a worm screw. See the figure below.

It sounds like you don’t want a motor that has a built in gearbox. In that case get a decent DC brushed motor like this
robotshop.com/ca/en/banebots … motor.html
Make sure you do your torque calculations after you know your gear-ratio.
Thanks for the reply! Was planning on using a worm gear in the gearbox to cover that. Sorry I do not know much about motors but when looking at the kv value of the motor i got an rpm of about 3650 for a voltage of 6V, would that matter at all?
Do you have an idea of the pulley diameter? Some values you need to know would be:
Motor RPM: 5000
Motor voltage: 6V
Payload: 20lbs
Pulley diameter: X
Can we assume the rope is around 1/2 of the pulley?
Note that most brushed DC motor (no gearing) rotate at ~10,000 rpm, so if you need 5,000 rpm, you would only be considering gearing in the 2:1 range.
Do not believe we will be using a pulley, the idea was to get a motor 1st, then design a gearset similar to what tronicsos had shown. We wanted to get a motor with an output relatively close to 5000 rpm at 6V, giving more torque and to make it less work for the gearing, and hopefully we have the right logic with that.
Without a pulley, how would you wind the cable / wire?
we will have a spool that the rope will wind around. We have not defined a size for this yet. We will probably use whatever we can find online easily.
Sorry, pulley / spool… meant it as a generalization. What would be the spool’s diameter?
It will probably be between 0.5 to 1 inches
Treat it as a simply torque problem with a known force (20lbs) and known radius (0.5 in). The torque required is simply 10lb-in (160oz-in).
You also provided the speed at 5000rpm, so you’re looking for a 6V, 160oz-in, 5000RPM brushed DC gear motor.
All higher RPM motors we offer operate at 12V, and reducing the voltage to 6V is not the best approach.
Given your needs, we don’t have a motor powerful enough nor do we have any suggestions.
