Motor Calculations:

We did speed calculations yesterday to determine what motors we want to use. The consideration for motors is speed vs. torque.

These were the options for motors:

• 1150 RPM
• 435 RPM
• 315 RPM
• 233 RPM

The inner circumference of the pulley (the portion that the string will actually wrap around) used in our sliders is 112 mm, which is 0.112 m.

1150 RPM Calculation: 1150 RPM * 0.112 m / 60 sec = 2.14666667 m/s

435 RPM Calculation: 435 RPM * 0.112 m / 60 sec = 0.812 m/s

315 RPM Calculation: 315 RPM * 0.112 m / 60 sec = 0.588 m/s

233 RPM Calculation: 233 RPM * 0.112 m / 60 sec = 0.434933333 m/s
