The Stationary Field Tooth Clutch(SFTC Series) was designed by SEPAC to deliver an exceptional torque-to-size ratio with the ability to operate dry or in oil. This model offers a bearing supported design to ease the installation process without relying solely onthecustomer for bearing support, and is virtually maintenance-free under proper operating conditions.

The SFTC’s positive engagement, less than one degree of backlash, high torque-to-size ratio and ease of installation make it suitable for a variety of applications. Additionally, the reliability of the SFTC Series makes it suitable for aerospace and defense actuators, aircraft flight control, military ground systems, weapon systems, elevator/azimuth, robotics, medical equipment/imaging etc.

The magnet body of the SFTC is typically installed onamotor or gearbox shaft with the option for a hub, coupling, gear, pulley or sprocket mounted to the armature.When current is applied to the coil, a magnetic field is created which attracts the armature (sliding on the adapter) towards the rotor. As the teeth engage, torque is transmitted.

When the power is turned off, springs between the armature and adapter assist in disengagement. The magnet body of the SFTC is held stationary by the means of an anti-rotation screw or post anchored to a hole provided.
