| 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 | ||||
| 3)The 10mm motors used with both the rotary and linear stages incorporate dual channel, 10 position, magnetic encoders. The resultant quadrature output is equal to 40 encoder counts per motor armature revolution. | ||||
| 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 | ||
| Encoder resolution calculations: | |||
| Encoder counts per shaft revolution | = 40 encoder counts x gearhead ratio | ||
| Minimum encoder count (inches) | = Lead (0.0125 in.) / Encoder counts per output shaft revolution | ||
| Minimum encoder count (millimeters) | = Minimum encoder count (inch)/39.27 x 10-3 | ||
| Minimum encoder count (micrometers) | = Minimum encoder count (inch)/39.37 X 10-6 | ||
| Conversion: | |||
| 1 inch (in.) | = 25.4 mm | ||
| 1 inch (in.) | =25,400µm | ||
| 1 millimeter (mm) | = 39.37 x 10-3inch | ||
| 1 micron (µm) | = 39.37 x 10-6 inch | ||
| 1 degree (deg) | = 3,600 arc-sec | ||
| 1 arc-sec | = 0.277 x 10-3 deg | ||
