Stationary Field Tooth Clutch from SEPAC Delivers Higher Torque in a Smaller Package

The SFTC’s positive engagement, less than one degree of backlash, high torque-to-size ratio and ease of installation make it ideal for a variety of applications. Additionally, the extraordinary reliability of the SFTC Series makes it a top choice 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 on a motor 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.

SFTC product highlights include:

• Static torque: 40 to 5200 lb-ft
• Max speed: 1400 to 3500 RPM
• 8 standard sizes available
• Magnet body diameter: 3.16” to 10.65”
• Overall length: 2.07” to 6.18”
• Rotor bore: .50” to 2.75”
• High temperature coil and insulation materials
• Easily modified for corrosive/moist atmosphere and environments
• Custom sizes and torques available
