Hello,
I’m confused about all the options. I need a 12V, 50mm, 150:1 linear actuator for my power wheels mod. I suppose I also need a control board for a standard RC controller. Can you make a recommendation please? Thanks.

The one spec you didn’t provide was the force. If you mean a Firgelli actuator:
robotshop.com/en/linear-actu … -12-p.html
robotshop.com/en/linear-actu … -12-s.html
For the -P actuator only:
robotshop.com/en/actuonix-li … board.html (for RC control)
Thanks for your response.
What is the force rating on the L16? I don’t actually know how much force will be necessary. It will steer a cart that holds up to about 50 lbs in the sand. What is the difference between the p16 and the L16? Should I look at standard actuators? (robotshop.com/en/firgelli-2- … uator.html). Will that work with the control board and RC? Thanks.
Paul
One more question. Can I use the -S with a standard RC receiver? If So, I don’t see the advantage of paying the extra $$ for the control board with the -P. Thanks for your help.

It comes down to how much force and speed you need. The L16 use more powerful motors than the L12, and also come in a range of stroke lengths, gearing (which affects the max force and speed) and input types. Steering in the sand requires more force than steering on ice. You’d ideally need to estimate of the force you will need.
The -S is two wire and cannot be used with an RC PWM output signal.
What is the weight/force rating on the robotshop.com/en/linear-actu … -12-p.html.
Do you carry the 63:1 ratio in the same configuration? Does that have the same rating?
Thanks.
The force rating can be obtained in the datasheet:
robotshop.com/media/files/pd … heet-2.pdf
A 150:1 gear ratio (for all L16) gives a force of
175N at 4mm/s at peak power
75N at 7mm/s at peak efficiency
200N max sustainable force
102N back drive force.
Hope this helps.
To be honest, I don’t feel like you’re being very helpful at all. Since I don’t know what force I need, the least you could do is give me some options based on your experience working with this equipment. I can order them from the manufacturer for a couple of dollars less. So it would be in your interest to be helpful rather than just spit out specs that I am unfamiliar with. Now I might be willing to go with the 2" Firgelli 35# p-feedback if I could find it on your site. BTW, your search mechanism is terrible. It is additive rather than subtractive - the more key words I put in the more results I get.
The force and stroke needed will depend on several factors:
]Where the actuator is placed on the wheel (how far away from the axis of rotation). If you put it close to the axis of rotation, a small extension of the actuator will result in the steering wheel moving a lot, but requiring a lot more force than if it was placed father away./:m]
]How much rotation you want from the wheel (determines stroke)./:m]
]The surface on which the vehicle is travelling (extreme example, but it’s harder to turn on sand than on ice)/:m]
Unfortunately we do not have any data regarding “force needed to turn the steering wheel of a power wheels children’s car” to suggest a specific force or stroke. We do not have one here to test. The 35 pound Firgelli actuator should be sufficiently powerful to rotate wheel at any location, but it’s hard to know if 2" stroke will be long enough to rotate the wheel.
We do apologize for the search and are always working to improve it. Although that issue is new to us, we will certainly figure out what’s going on and solve it ASAP.
