Product catalog summary
Design Characteristics
  • Technology: The EC25 is an electromechanical wrap spring clutch.
  • Low Wattage: Requires only 2.5 watts for engagement.
  • High Torque, Small Package Size: Provides 25 lb-in (2.83 N-m) of torque with dimensions of approximately 1.2 inches in diameter and 1 inch in shaft length.
  • Rapid Acceleration: Accelerates loads from zero to full speed in less than 3 milliseconds.
  • Consistent Performance: Engagement occurs with minimal slippage and disengagement is nearly instantaneous.
Power Source

Operates on either filtered or unfiltered DC power, with filtered power recommended for better performance at high speeds.

Application Considerations
  • Single Direction: Provides torque only in the direction of wrap-down, allowing for overrunning.
  • Relative High Shock: Rapid acceleration can cause significant system inertia effects; an in-line slip device may be used for shock absorption.
  • Engagement Relative to Speed: Relies on relative motion between input and output for engagement; slower speeds result in longer engagement times.
Operating Parameters
  • Optimal performance within 0°- 40° C (32°-104° F).
  • Typical operating speed is 100-800 rpm, with a maximum of 1400 rpm.
  • Minimum load friction torque is 6 oz-in (0.05 N-m) plus customer input bearing torque.
Product Overview

The EC25 clutch is ideal for applications requiring consistent performance over 1 million actuations at 25 lb-in (2.83 N-m) of load. It is designed for easy assembly and low power consumption, offering high-quality performance and increased torque capacity at a competitive price.

Available Options
  • Direction: CW or CCW.
  • Bore: 6mm or 1/4 inch.

Clutch ::  EC25 -1

Operating Parameters Technology Single Direction Engagement Relative to Speed Relative High Shock EC25 performance is best within the following conditions: ҕ0- 40аC (32-104аF) 100-800 rpm typical, 1400 rpm max. ՕMinimum load friction torque 6 oz-in (0.05N-m) plus customer input bearing torque. Electromechanical wrap spring clutch. Wrap spring clutches provide torque only in the direction in which they wrap down. This allows for overrunning. The EC25 relies on relative motion between the input and output for engagement. Thus, the slower the speed, the longer the time until engagement. Due to the EC25srapid acceleration, system inertia effects can be significant. In some applications an in-line slip device may be used for shock absorption. Low Wattage Rapid Acceleration High Torque, Small Package Size Consistent Performance Power Source The EC25 requires only 2.5 watts of power for engagement. After spring wrap-down, the EC25 will accelerate loads from zero to full speed in less than 3 milliseconds. The EC25 provides 25 lb-in (2.83 N-m) of total load over a life of 1 million actuations with an outside diameter of about 1.2 inches (30mm), and a shaft length of about 1 inch (27mm). Engagement is made with virtually no slippage and disengagement is almost instantaneous. All Reell clutches operate on either filtered or unfiltered dc power. The use of filtered power is recommended for better life at high speed. Innovative Torque Solutionswww.reell.com >
