Technology - English
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 27mm (1 inch). Part weight is 83g (.184 lbs)
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.

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.

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.
