Since the feed-rate in most applications
requires much less than standard 1725 RPM DC
motor speed, you must connect a speed reducer
between the motor and the reel. You can use the
following formula to calculate gear ratios.
S ( 3 . 1 4 ) d
F
Where:
R
= step-down ratio between motor and reel
F
= maximum machine feed-rate (units of measure/min)
d
= reel hub diameter (units of measure)
S
= motor speed (RPM)
In order to allow some margin for feed-rate
increase, a motor speed (S) less than maximum
should be used; for example, for a motor rated at
1725 RPM, calculate the ratio for 1500 RPM.
Sample Calculation:
(1500)(3.14)(6)
1000
Where:
S
= 1500 RPM
F
= 1000 units of measure/min
d
= 6 units of measure
