Suggestion: motor for medium-high load

Using Arduino Motors, Mechanics, Power and CNC

Hi all guys,
I just need one suggestion about the choice of one electric motor for move a medium-high load - about 100kg.
My needings are not to have a motor with high number of rpm, infact as I have projected 100-120 rpm are the maximum rortation frequence that I need.
I just have loocked in some topics and probably the best choice in this case is to buy an asynchronous (ac) motor.
The difficult point is that I want to control the motor with arduino, so I'm interested to use an dc/cc motor for make all more easier.

You have some suggestion for me to buy a dc motor that can move about 100 kg, who can be arduino speed controlled (PWM)?

Thank you so much.

You need to work out the torque, not the force. Explain how the load is attached, with measurements, we can help work it out.

Hi Mark,
the load is applied on two axes with two wheels for each axis.
My idea is that just one axis will be engine powered.
The project is a simple plan of sheet metal where I will load on top a electric generator and other objects.
In total I expect about 100 kg of mass.

I've noted that in some cases for loading of about 100 kg, some people use 2 engine at 500W 24V direct current.

Thanks.

Possible heavy lift geared motor devices that might be modified for use.

Without measurements theres not enough to go on. Wheel diameter?
Any gearing? Max speed? Max acceleration? Max slope?

Hello.
Wheel diameter about 40 cm.
I have not provided any gearing at moment. For the transmission I've looked for chains or belt.
Max speed, for my requirements at least 5 to 8 km/h.
Slope of effective working it will be near to 1%.

Hope this informations can clarify something.
I have seen the links. Just one of two motor is in dc (12v).
For me is better 'cause I can control more easy with one PWM controller as sabertooth.

Thank you.

I have posted two links. One will help you calculate what torque you need and the other is a good place to find beefy motors (DC).

chains or belt is gearing - what ratio? Or is that something you can choose to match a motor?
