MaalonDrive® HighAcc 6mm – Type 2
The MaalonDrive® HighAcc 6mm – type 2 micro servo actuator is driven by a brushless DC motor with rated voltage of 6V and integrated encoder with a resolution of 128 pulses per rotation.
At the heart of this extremely miniaturised and yet absolutely reliable micro positioning system is a zero-backlash MaalonDrive® gear with a reduction ratio of 120:1.
By means of the preloaded ball bearings on the output shaft, the application can be directly connected.
Benefits
1) High repeatability
2) Compact build up
3) Lifetime lubrication
4) Preloaded ball bearing
5) Zero backlash at high torque capacity
