Max radial load on DC-Geared motor SPG30-300K

[ksyew]

I;m currently involved in a RC vehicle design which can be apply load up to 15-20kg. I am using 4 DC motors on four identical 7cm diameter wheels. Is the SPG30-300K motor suitable for this application? Or any motor suit best with this application?

Any reply would greatly appreciated. Thanks!

Not really know how to calculate. It will depends on many factors beside the gear ratio and torque of motor; the wheel size, the load..... Yes, you have all the information.... but I don know the formula Sorry.

Thanks robosang, I have done the torque calculation and it seems to work well with load of 15kg. My only concern is 15kg load might spoil the motor because I have no information about the maximum radial load of the motor. I'm not sure if it can be calculated or the info should be provided by supplier. Any idea? Thanks!

normally the low cost material does not have all the data as the manufacturer does not run the testing to obtain such data. I am not sure whether Cytron have those parameters, but I normally run try first and learn from result. Ya, you might waste some money But you will learn a lot, that is my way

Ya, that's true, spending some money and get some trial and error is the best way.
But you know what, i sent the question to the supplier and they replied me
"radial load (10mm from flange)1kgf.cm"
However, I'm quite confused with that because the unit given is in torque but not in force.
