The Model EC15 transfers up to 1.7 N-m (15 lb-in) of total
load with consistently repeatable performance for one million actuations.
Reell's clutches are designed for easy mechanical and electrical assembly
and for low power consumption. The EC15 offers high quality performance
and increased torque capacity at a competitive price.

Design Characteristics
Technology |
Electromechanical wrap spring clutch |
Low Wattage |
The EC15 requires only 2.5 watts of power for engagement |
High Torque, Small Package Size |
The EC15 provides 1.7 Nm (15 lb-in) of total load over a life of 1 million
actuations with an outside diameter of about 30mm (1.2 inches), and a shaft
length of about 1 inch(27mm). |
Rapid Acceleration |
After spring wrap-down, the EC15 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. |
Application Considerations
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 EC15'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 EC15 relies on relative motion between the input and output for engagement.
Thus, the slower the speed, the longer the time until engagement. |
Operating Parameters |
EC15 performance is best within the following conditions:
- 0°- 40° C (32°-104° F)
- 100-800 rpm typical, 1400 rpm max.
- Minimum load friction torque 0.05 N-m (6.0 oz-in)
plus customer input bearing torque.
