Currently working on a project to design a personal transportation device and am in the process of teaching myself about motors, receivers, etc.

I am using 2 of these motors: https://www.digikey.com/en/products/detail/ebm-papst-inc/VG-ECI6340BK1-P63-1-5/9598038

But, I am struggling to figure out the best way to power and control the motors due to the limited amount of space in the device.

Firstly, how do I figure out what power supply can be used? I made a small scaled version and was able to use a 12V output battery pack that just used 8 double As, but this motor is much bigger than those motors.

Next, I plan on using an RC transmitter and receiver (like for model airplanes) to control the motors, since they only need to rotate clockwise and counterclockwise. However, I am unsure of how to connect all of these items together. Would there be a better method of controlling the motors? I am not well verse in Arduinos and programming, but am willing to learn if it can simplify the process and/or limit the amount of parts that are needed in the controlling and powering of the device.

Any help is appreciated!

 

For power supply/battery, Have you looked at electric bike compact power supply?
Not sure if the RC type ESC motor controller would work in this application, but maybe worth looking into.

 

The Motors that You have chosen are NOT for beginners.
They are quite complex, and require a matching Control-Box.
They are also not powerful enough to be used with a ~200-pound Load.

One good rule for design engineering is to have a good idea as to how a system will work prior to selecting and acquiring components. This rule allows design changes without a lot of expense. If the speed and torque requirements of these motors are correct for the acceptable performance of the intended device, then the next consideration will be the electrical power and the amount of stored energy needed to deliver that power over the desired time period. THAT will determine that size of the required power source.
And now the question of who would be transported. For a pet mouse, the 8 AA battery pack could be adequate, for a human being, probably not.
Then consider the price: the Digikey offering is good quality but at $540 each they are rather expensive.
And you still do not have the drive portion, which is needed since these motors can not work with drive wheels using the motor shaft bearings to support the load.

 

Welcome to AAC.

Those are lovely motors, how did you happen to choose them?

Beautiful as they are, they don’t seem suited to your application for several reasons. But without knowing what your device is expected to do (maximum speed, maximum load, etc.) it’s really not possible to give much useful advice.

My immediate reaction is that a couple of surplus wheelchair motors would be 10 time as suitable at 1/10 the cost.

 

If not actual wheelchair motors, the drives from a failed mobility scooter. Those have the adequate bearings and possibly even the useful mounting provisions. AND you may possibly get the wheels and tires.
But as we have no hint of what the intended device will resemble, these are at best guesses. Personal transportation device could be a hoverboard or an electric dirt bike. Or a Cushman scooter.

 

Okay, hi everyone. Thanks for all the responses.

I am realizing I didn't provide enough information, so here's my plan

The goal is to make an rotating spherical hoverboard prototype. The design requirements are to be able to move 30lb of weight (not including the internal and external components of the device, so in total around 70lb) at a minimum speed of 5mph.

I have been through multiple design iterations, each requiring motors with different specs.

Below is a rough section view of what the internal of my latest iteration is intended to look like.

So, the idea was to create a process similar to how a baseball pitching machine works. The wheels that are each attached to their own individual motor will be able to propel the ball forward and backward (ie rotate around the x-axis) when they wheels rotate in the same direction, And the ball will turn (ie rotate along the y-axis) when the wheels spin opposite of each other. The power source, receiver, and motors will all be housed in the hood of the board, that will have ball bearings on the underside so the sphere can move freely.

So, now back to the motors. The math I did for a 10" ball and two 2.55" wheels holding 75lb and moving at a speed of roughly 5mph, gave me the following specs for motors:
rotational speed: >660 rpm
torque: >2.16Nm

The motors in the link I provided meet these specs and follow the size constraints, but I still have yet to order them. I've spent some time now searching, but am open to continue if it means finding something easier for me to use. (I am studying mechanical engineering, so I am not a complete beginner, but surely the more things that can be simplified the better)

 

Good on You for thinking "outside the Box".
Unfortunately You still have a lot to learn.

I would suggest that You start-out with a much smaller model,
that would be orders of magnitude less expensive,
to create a "proof-of-concept" model, FIRST.

You are going to find many reasons why You do not see these for sale,
and,
You will fail many times before You get to an actual working model,
that's just the way that inventing works,
for everybody.
