Given:
Motor voltage = 4.6 vdc
Gearhead = 64:1
GH = Gearhead
RPM/volt =4727
80 pitch leadscrew (1/80 = 0.0125 inch or 0.3175 mm)
Calculation:
(4727 RPM/volt)(4.6v)(1 RPS/60 RPM)(1 GH rev/64 mtr rev)(0.3175mm/GH rev)= 1.79786 mm/sec
and
for 87 mm radius stage: θ = tan-1(1.79786/87) = 1.1839 deg/sec
and
for 120 mm radius stage: θ = tan-1(1.797812087) = 0.8584 deg/sec
Given:
1 motor rev = 200 quadrature counts (50 counts/mtr rev x 4 = 200)
Calculation:
(1mtr rev/200 counts)(1 GH rev/64 mtr revs)(317.5 μm/GH rev) = 0.0248046875 μm/count
and
for 87 mm stage and 1μm resolution: θ=tanˉ¹(1E-6/87E-3) = 6.58572178284E-4 deg/μm
and
(0.0248046875 μm/count)(6.58572178284E-4 deg/μm) = 1.63356770785E-5 deg/count
or
(1.63356770785E-5 deg/count)(3600 arc-sec/1deg) = 5.88084374826E-2 arc-sec/count
and
for 120 mm stage and 1 μm resolution: θ = tanˉ¹(1E-6/120E-3) = 4.77464829264E-4 deg/μm
and
(0.0248046875 μm/count)(4.77464829264E-4 deg/μm) =1.18433658821E-5 deg/count
or
(1.18433658821E-5 deg/count)(3600 arc-sec/1 deg) = 4.26361171756E-2 arc-sec/count
1 inch = 25.4 mm
1 inch = 25,400 μm
1mm = 39.37E-3 inch
1μm = 39.37E-6 inch
1deg = 3600 arc-sec
1arc-sec = 2.77777E-4 deg
1) Max travel rate calculated with motor armature running at a maximum speed of 20,000 RPM.
2) The 6mm motors used with linear stages incorporate dual channel 50 position, optical encoders. The resultant quadrature output is equal to 200 encoder counts per motor armature revolution. Speeds measured at 4.5 VDC with 64:1 gearhead
