50:1 Micro Metal Gearmotor HPCB 6V with Extended Motor ShaftProduct Code: 2117
£14.36 ex VAT
This 50:1 micro gearmotor is a miniature high-power, 6 V brushed DC motor with long-life carbon brushes and a 51.45:1 metal gearbox. It has a cross section of 10 x 12 mm, and the D-shaped gearbox output shaft is 9 mm long and 3 mm in diameter. This version also has a 4.5 x 1 mm extended motor shaft.
These tiny brushed DC gearmotors are available in a wide range of gear ratios€”from 5:1 up to 1000:"”and with five different motors: high-power 6 V and 12 V motors with long-life carbon brushes (HPCB), and high-power (HP), medium power (MP), and low power (LP) 6 V motors with shorter-life precious metal brushes. The 6 V and 12 V HPCB motors offer the same performance at their respective nominal voltages, just with the 12 V motor drawing half the current of the 6 V motor. The 6 V HPCB and 6 V HP motors are identical except for their brushes, which only affect the lifetime of the motor.
The HPCB versions can be differentiated from versions with precious metal brushes by their copper-colored terminals. Note that the HPCB terminals are 0.5 mm wider than those on the other micro metal gearmotor versions (2 mm vs. 1.5 mm), and they are about 1 mm closer together (6 mm vs. 7 mm).
