Dynamatic, Formerly Eaton Dynamatic, Friction Brakes, Clutches, Clutch/Brakes & Motor Brakes

Produced for many years by Eaton Dyanamtic in Kenosha, WI the Dyanamatic Electromagnetic friction brake works on the principle of an electromagnet. It consists of two basic parts: The Field Magnet and the Armature Plate.

When a D.C. voltage is applied to the coil, located inside the field magnet, the armature plate is attracted to the field magnet; By means of friction contact between the two members, torque is transmitted. The friction material located in the field magnet helps to stabilize the torque output and prolong the wear life of the brake. Friction Brakes are used to stop a rotating load (see Fig 1).

Dynamatic Clutch-Couplings

Clutch couplings are used to couple in line shafts between the prime mover (motor) and the load (fig 2.)

Figure 2

Dynamatic Clutches

Are used when the load shaft is driven by a belt, chain or gear

Figure 3

Dynamatic Clutch-Brake-Couplings

Are used to combine functions of a clutch and brake in a compact assembly
