Permanent Magnet Hysteresis Brakes

These brakes use permanent magnets to produce a drag torque and require no electricity for operation
Drag torque is constant and independent of slip speed
Torque on each unit can be adjusted to any value between bearing drag (~0) and the max torque indicated in the table below
Select brake based on torque requirement
Refer to heat curve on product data sheet to ensure speed and torque of your application will not exceed heat rating of brake
Refer to bending moment rating on product data sheet if you plan to place your spool directly on the brake shaft
For heavy spools, consider using one of our HD models or supporting your spool with a separate bearing structure
Refer to product data sheet for dimensional data. our customer MUTT

Common Applications

Wire Payoff
For decades, Magnetic Technologies permanent magnet hysteresis brakes have been used around the world for wire payoff applications. Our brakes are ideally suited for this application because they provide a constant torque year-after-year. With no wearing parts, our brakes last for many years without needing any servicing. We offer a full range of permanent magnet hysteresis brakes for new applications, competitive brake replacement, or retrofit to an existing payoff.

Torque Overload Clutch
By driving the body of our brake and using the shaft as an output, these permanent magnet hysteresis brakes can be used as an adjustable inline torque limiting clutch. The brake will drive without slip until the torque set point is exceeded at which point the brake will slip smoothly. When torque is decreased below the torque setpoint, the brake will continue driving smoothly without any damage to the brake or any other torque sensitive components.

Drag Brake
Our brakes can be used to create an adjustable drag. Whether you are simulating drag on a motor or creating resistance on exercise equipment, our constant torque brakes allow for continuous slip without any wear or electricity requirement. You can count on our brakes to give a consistent and repeatable drag on your process.

Backstop Brake
Because our brakes require no electricity to operate, they work great as a failsafe in the event of power loss. For positioning applications such as linear stages or motor-driven lifting applications, in the event of power failure our brake will hold or slow any resulting motion keeping operators out of harms way.
