RS022 Miniature Magnetic Servo Clutch for Servo Gear Protection
Overview
The miniature servo magnetic clutches from DAGU fit on your servo just like a standard servo horn
Unlike a standard servo horn, these clutches will slip when excessive force is applied to prevent your servo gears from breaking
Typical holding torque for the standard configuration is 850g/cm
Features
The drive plate fits onto the servo horn and holds 4 magnets
There are two drive plates provided in the kit
One has 8g and the other 9g molded on the side that faces the servo
The difference between the two is the size of the spline in the centre
The mounting plate holds 4 magnets, comes in 3 different shapes and allows various devices to be mounted into de servo just like a normal servo horn
The glassine, low-friction disk sits between the two clutch plates and combined with the brass sleeve allows the clutch to drive smoothly almost without friction
The 8 magnets are firmly press fitted into the clutch plates and depending on how you install them the clutch can be configured for 3 different modes of operation
Hard Lock occurs when the magnets are attracted to each other. Once the magnets stick together they lock and resist being separated
Soft Lock occurs when the magnets are repelling each other. This provides a soft spring action. Locking occurs when the repulsive force is at it's maximum
Standard Servo Mode :
The clutch "hard locks" in place every 180 degrees
When the clutch slips less than 180 degrees it will spring back into the locked position automatically and relocks
If the clutch is forced to slip more than 180 degrees then it will attempt to relock 180 degrees from the original position
Continuous Rotation servo - Hard Lock:
The clutch "hard locks" every 90 degrees
This mode works best with wheels where slippage is not normally desirable
Continuous Rotation Servo - Soft Lock:
The clutch "soft locks" every 90 degrees
Soft lock has a spring action and provides maximum protection for your servo gears
It is best suited for wheels travelling over rough terrain
