Re: Relationship between wheel type and power
with the same rpm (same drive motor/gears) the edge of a large wheel has a faster surface velocity than a smaller wheel.
Power is not as straightforward. A larger wheel has higher speed but less torque. Technically the power is the same - the power is the amount of power your motor is putting into the wheel. If you connect a 1 HP motor, then you have one HP available. energy is what you really need to look at. At the same RPM a heavier or larger diameter wheel will have more rotational intertia (energy) than a smaller one. When a ball comes in contact with the wheel, a larger one will have more stored energy to transfer. |
