Module 6: Power Transmission
A motor produces one speed and torque curve. Power transmission is how you trade one for the other until the mechanism does what the strategy requires. This is the most quantitative module in the track.

What This Unit Covers
Read a motor curve and find the operating point where a mechanism actually runs.
Compute gear ratios across multiple stages and predict output speed and torque.
Size chain and belt drives, including center distance and length.
Account for efficiency losses and backlash instead of assuming ideal transmission.
Review the sequence and goals here, then resume at your first incomplete lesson.
