Series 4EC Electromagnetic
Single-Face Clutches

Stationary Field
for Dry Operation
Series 4EC electromagnetic stationery field single-face
clutches are zero backlash and designed for dry use.
When the coil is energized by the DC voltage a magnetic
field is generated which attracts the armature to the
rotor hub, providing the clamping force for torque
transmission. The armature is spring-loaded to ensure
rapid disengagement and zero drag when disengaged.
Various clutch configurations are available to suit
different drive installation requirements.
Features
•t Zero backlash
•t Long life asbestos-free friction material
•t Stationary field design eliminates brush gear
and simplifies supply connection
•t Zero drag torque when disengaged
•t Efficient magnet design reduces power t
consumption and heat generation
•t Can be used as a continuously slipping t
variable torque device for torque limiting t
and tensioning applications
•t Ideal for high cyclic and all other clutch
duties
•t Sealed for life bearings
