 ELECTROMAGNETIC
BRAKES & CLUTCHES

 

S G Transmission manufactures a large range of electromechanical brakes and clutches for motion control applications. All products are manufactured to ISO 9001 and are backed by 40 years experience. Lean efficient manufacturing ensures that delivery times kept to a minimum and small quantity orders are not a problem. S G Transmission also has a dedicated design service for customised solutions.

Sometimes, motion control problems can be solved using electromagnetic brakes and clutches or torque limiters with conventional AC motors instead of expensive stepper and servo motor systems. Motors can be left running at constant speed instead of inefficiently ramping up and down. Electromagnetic brakes and clutches can couple a motor to a load at the required times.


The clutches and brakes use efficient 24 VDC electromagnets with fast response times. S G Transmission also winds their own coils so they are able to adapt their products to unusual voltage requirements.
The S G Transmission brake and clutch products are generally interchangeable with most of the European and American types in the market, upto a size of 200mm diameter. 
S G Transmission wil also design and build to special customer requirements.
