SEPACModel SFTC Series -Stationary Field Tooth Clutches

SHARE

Stationary Field Tooth Clutches; 3 to 10.5” diameter; 2 to 7.5” length. Bore sizes from 0.5 to 4.25”. Static torque from 40 to 5200 lb-ft. 1400 to 3500 RPM. Operates both dry and in oil. Modified designs and customized assemblies available.

When current is applied to the coil in the stationary magnet body (held from rotating by an anti-rotation pin), a magnetic field is created which attracts the armature toward the rotor. As the teeth engage, torque is transmitted.

When the current is turned off, the armature slides on the splined output plate adapter. Springs pull on the armature to assist disengagement from the rotor.
