Efficieny: 2.7W Gear Type: Planetary Gear Ratio: 43:1 Bearing Type: Dual Ball Bearing Shaft size: 4mm (0.1575”) Net Weight: 92g (3.25oz) Pulse Per Revolution: 3 BulletPoint4 : Note: Stall Torque is the torque which is produced by a motor when the output rotational speed is zero, it may also mean the torque load that causes the output rotational speed of a motor to become zero - ie to cause stalling. BulletPoint5 : Electric motors continue to provide torque when stalled. However, electric motors left in a stalled condition are prone to overheating and possible damage since the current flowing is maximum under these conditions.
