Technology
|
Electromechanical wrap spring clutch |
Low Wattage
|
The EC25LL requires only 2.5 watts of power for engagement |
High Torque, Small Package Size
|
The EC25LL provides 2.83 N-m (25 lb-in) of total load over a life of 1 million actuations with an outside diameter of about 30 mm (1.2 inches), and a shaft length of about 30 mm (1.2 inches). Part weight is 83 g (0.184 lbs). It also provides approximately 60 million bearing revolutions for typical applications. 2 - 10 times the bearing life of a standard EC25. |
Rapid Acceleration
|
After spring wrap-down, the EC25LL will accelerate loads from zero to full speed in less than 3 milliseconds. |
Consistent Performance
|
Engagement is made with virtually no slippage and disengagement is almost instantaneous. |
Power Source
|
All Reell clutches operate on either filtered or unfiltered dc power. The use of filtered power is recommended for better life at high speed. |
Operating Parameters | EC25LL performance is best within the following conditions:

Single Direction
|
Wrap spring clutches provide torque only in the direction in which they wrap down. This allows for overrunning. |
Relative High Shock
|
Due to the EC25LL's rapid acceleration, system inertia effects can be significant. In some applications an in-line slip device may be used for shock absorption. Please contact a Reell Sales Representative for more information regarding this option. |
Engagement Relative to Speed
|
The EC25LL relies on relative motion between the input and output for engagement. Thus, the slower the speed, the longer the time until engagement. |
