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
