Nidal Copal's HG16 series is a RoHS compatible DC motor with planetary gearbox. The 0.63 inch OD (16 mm) DC motor has two axial lengths of 1.42 inches (36 mm) and 1.57 inches (40 mm); they develop rated gear motor torques of 3.47 oz-in at 310 rpm, 4.86 oz-in at 175 rpm and 6.94 oz-in at 85 rpm.
Three windings are available: 6 volt, 12 volt and 24 volts. The 0.63 inch OD by 0.63 inch long planetary gearboxes are integrated with the DC motor to create a gear motor package. A 30:1 gear ratio is used with the HG 16-030 model, a 60:1 gear ratio with the HG 16-060 model and 120:1 and 240:1 gear ratios with the HG 16-120 and HG 16-240 models, respectively.
