Notes:
1) The lead values shown above in both travel rate and resolution calculations, are for 80 (1/80) Thread per Inch (TPI) leadscrews. For a 40 TPI leadscrew, substitute 0.025 inch lead.
2) Max travel rate calculated with motor armature running at a maximum speed of 20,000 RPM
*The resultant quadrature output is equal to 64 encoder counts per motor armature revolution. (mtr rev)
Travel rate calculations:
Output Shaft RPM = RPM of motor / Gearhead Ratio
Distance per minute = Output shaft RPM x Lead (0.0125 in, 0.3175mm)
Distance per second = Distance per minute/60
Distance in millimeters = inch/39.37 X 10-3
Distance in micrometers = inch/39.37 x 10-6
Conversion:
1 inch (in.) = 25.4 mm
1 inch (in.) =25,400µm
1 millimeter (mm) = 39.37 x 10-3 in.
1 micron (µm) = 39.37 x 10-6 in.
1 degree (deg) = 3,600 arc-sec
1 arc-sec = 0.277 x 10-3 deg
