I am trying to build a worm gear based on a single axis solar tracker for a worm gear box. I need some guidance choosing a worm gear & drive motor for the application. These are the steps I have explored so far - if I am wrong could someone please give links to material which gives a good explanation so I can learn and understand it better.
Motor planning to choose; Worm gear selection
General equations for worm gear & motor:
1) $Efficiency = \frac{\text{output Power of worm gear}}{\text{input Power of worm gear}} = \frac{P_o}{P_\text{Input}}$
2) $\text{Output power} = P_o = 2*\pi*\text{Output speed} * \text{Output torque}/60$
- Output power in kW
- Output speed in rev/min
- Output torque in Nm
3) $\text{Input power} = P_\text{Input} = 2*\pi*\text{Input speed} * \text{Input torque}/60$
4) $\text{Net Torque}= T_\text{output} + T_\text{Input} + T_\text{holding} = 0$
In order to drive a 250 kW plant I have assumed 15 kW per row, this gives me 16 rows with 1 column.
The worm gear has to drive 16 rows with coupling with single column item.
Each panel weighs 20 kg and there are 60 panel per row which gives 1200 kg. Each row has a structural weight around 700 kg.
This gives a net weight of 1900 kg per row.
So, the load on the worm gear would be 1900*16 = 30400 kg.
Based on my calculations above, how can I calculate the exact motor & drive motor required. I need some specific relation here.
