Alternative product of Hysteresis Coupling

Hysteresis coupling(and magnet coupling)  is a mechanical product to transmit torque by using magnetic force.

For example, it would be used for packing machine and motor protect when over torque is loaded to.
However the hysteresis coupling might have disadvantage on cost-wise and dimension. 
Now we would like to introduce you our magnetic torque limiters. 

TOK’s magnetic torque limiters work as same as hysteresis coupling.

Usage applications are: 
●  Motor protection 
●   Robot arm 
●  Electric driver 
●  Tensioner for paper feeding machine(ex. ATM, Copy machine, Flim roller etc.) 

TOK’s torque limiters have been developed especially for monetary instruments and copy machines for more than 20 years.　
However you can consider to use our limiters for other applications. 

Now we recommend you magnetic torque limiter TLEU series. 

Specification overview: 

●   Outer diameter: φ22.5 
●   Bore diameter: φ10 
●  Max torque: 45mN・m 
●   Allowable revolution speed: 2,000 r.p.m (at the maximum) 


And we have TLES series.

Alternatively you can consider our torque limiters which provide you with compact space, light weight, cost-effective compared to hysteresis coupling.

We believe that our magnetic torque limiters would help you improve your productivity.

Magnetic torque limiter

What is a magnetic torque limiter?

It generates torque from magnetic hysteresis resistance.

The magnet does not slide so magnetic torque limiter is more durable.

Advantages of using a magnet torque limiter compared with a coil spring torque limiter:

1.       High durability

2.       High speed revolution

3.       Stable torque

4.       Minimal sliding sound

　　　　TLEU series                                                   TLES series
