Discussion Overview

The discussion revolves around finding a suitable plate for mounting a high-speed electric motor to a wheel, specifically addressing the requirements for handling speeds of 700-800 RPM. Participants explore various mounting solutions and the mechanical considerations involved in the setup.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant expresses concern that standard household "lazy susan" bearings may not support the required RPMs or loads.
  • Another suggests that a wheel from a go-kart or similar vehicle could be a suitable option, potentially available from local junkyards.
  • A participant clarifies the need for a plate that can handle the specified RPMs and emphasizes that they already possess the wheel.
  • It is noted that car or go-kart wheels typically come with bearings that may meet the RPM requirements, although bicycle bottom brackets might also be considered despite their design limits.
  • A request for a clearer description of the project is made, with a preference for a drawing to better understand the requirements.
  • The original poster specifies the motor's shaft dimensions and shape, indicating the need for a revolving swivel plate that can accommodate the setup while ensuring the drive shaft does not shear the wheel at the attachment point.

Areas of Agreement / Disagreement

Participants generally agree that standard lazy susan bearings are inadequate for the specified RPMs. However, there is no consensus on the best mounting solution, with multiple suggestions and considerations presented without resolution.

Contextual Notes

Participants have not yet provided specific details on the mechanical properties required for the plate or the exact nature of the loads involved. The discussion lacks definitive conclusions regarding the best materials or designs for the mounting solution.

Who May Find This Useful

Individuals interested in high-speed motor applications, mechanical engineering, or DIY projects involving electric motors and wheel assemblies may find this discussion relevant.

A wheel from a go cart or similar would fill the bill. Any junkyards in your area?
 
I don't really know what you mean. I need a plate that can handle 700-800 RPMs. I already have the wheel, just need to find a way to mount it.
 
Car or go cart wheels usually come attached to a bearing that would serve your RPM requirements. You are quite right that a lazy susan bearing will not work for you.
The bottom bracket of a bicycle might work, the bearings are decent, although 700 rpm is several times more than they designed for as well. However, there is a through shaft, allowing for the motor and the wheel to be easily mounted.
 
We need a better description of what you are trying to achieve. A drawing is preferred.
 
I have a motor with a 1/2" shaft with a "D" shape. I am trying to drive a 30cm wheel with this motor. I need a revolving swivel plate like this - http://www.aliexpress.com/item/6-5-...re-hardware-barstool-turntable/550860671.html - that will hold the wheel. It needs to handle 700-800 RPMs. The motor shaft will go into the wheel on top and drive it.

I will post a drawing once I am off work. I need to know what kind of adapters I need for the shaft and wheel so the drive shaft doesn't shear the wheel at the point of attachment.
