A few of the many possible applications include: X-Y tables, medical instruments, office equipment, index tables, and robotics.
The 42 mm gearheads supplied with NEMA 16 and 17 steppers are available in six standard ratios (3.6:1,7.2:1,9:1,10:1,18:1, and 36:1), and custom ratios are available. The gearmotors current ratings are from 0.6 A/phase to 1.20 A/phase at 3.6 to 4.0 V. Holding torque is from 1.73 lb-in. (0.2 Nm) to 6.94 lb-in. (0.8 Nm) and the Step Angle (full step) is from 0.250° down to 0.050°.
The 60 mm gearheads supplied with NEMA 23 steppers are also available in six standard ratios (3.6:1,7.2:1,9:1,10:1,18:1, and 36:1) and custom ratios are also available. The gearmotors current ratings are from 0.85 A/phase to 1.50 A/phase at 4.0 to 8.6 V. Holding torque goes from 8.67 lb-in (1.0 Nm) to 34.7 lb-in (4.0 Nm) and the Step Angle (full step) is from 0.250° down to 0.050°.
SEI also supplies custom gearheads for OEMs without steppers.
