[16RPM 12 V]

Description

Specifications:
Nominal voltage: DC 12 V / 24 V.
Idle Speed: 7 RPM, 10 RPM, 12 RPM, 16 RPM, 27 RPM, 40 RPM, 80 RPM, 160 RPM, 260 RPM, 470 RPM
Maximum power: 5W
Maximum torque: 70 kg.cm.
Shaft diameter: 8 mm, D type
Shaft length: 15 mm.
Torque:
Torque Unit: 1N M = 10 kg. cm = 0.1 kg. medium / 1
Torque = (tension vertical for lever arm) x (lever arm)
For example, the left picture:
Drum Lift, Drum Radius = Arm = 10cm, Lifting Weight = 5kg
Torque required = 5kg x 10cm = 50kg cm.
For example, the right figure:
Drum Lift, Drum Radius = Arm = 5 cm, Lifting Weight = 5 kg.
Torque required = 5kg x 5cm = 25kg. cm
