SE14 High Tilting Torque Slew Ring Drive Attached With AC Motor For Construction MachineryNEMA 34 enclosed stepper motor
Description
A: Bearing inner ring+ball+bearing outer ring = BEARING
B: worm+wormwheel = Worm and wormwheel structure
If adding gear to the outer ring of the bearing, then A and B become a slew drive.
Maintain advantages: large torque, good sealing, high bearing force of the end cover.
It can be matched with AC motor, DC motor, synchronous motor, brushless motor. There are also other motors could be matched, no matter what motors we choose, basically we need to look at some parameters: 1. Rated power/torque during normal operation 2. Normal power/ torque during a stable state; 3. Tracking accuracy; 4. adapt to temperature environment; 5.IP grade, waterproof, dustproof; 6. Economic reference; 7. service life; 8. Tracking speed, etc.
Tracker, tracker, tracker, why?
Because of sunrise and sunset…
Wrong – the sun doesn’t rise and set.
But it appears to rise and set because of the Earth’s rotation on its axis.
So solar trackers are counteracting Earth’s rotation.
