Flange Mounted/Foot Mounted Clutch-Brakes
DIMENSIONS
When D.C. voltage is supplied to the clutch coil the armature is attracted toward the clutch rotor. This clutch engagement accelerates the output shaft (load) to the driven speed. Removing the voltage from the clutch coil and applying it to the brake coil causes the armature to release from the clutch and engage to the brake. This stops the output shaft (load). The single armature prevents simultaneous engagement of the clutch and brake (overlap).
EMTorq clutch-brakes require D.C. supply voltage from A.C./D.C. rectification. Switching on the A.C. side provides a slower engagement/disengagement time. Switching on the D.C. side provides a faster engagement/disengagement time. Use a suitable arc suppressor and capacitor to protect the clutch and brake coil and switch. Engagement/disengagement time is a function of the air gap and type of switching.
