AC Series
The Electromecanical spring brake series AC can be fed both in alternating or direct current. Purpose of the brake is to determine the arrest of the rotatory movement of the shaft coupled with it.MINI.jpg)
The main caratheristics of Series AC brake are:
- Extremly Strong Structure;
- Simplicity of assemblage;
- Silent in the interventions (<70 dBAs in accord with the directive 98/37/CEE)
- Spool of the electromagnet cemented with epossidic resin.
Operational
In the draw have been indicates the main elements that constitute the selfbreaking motor.
The brake is projected to guarantee, intrinsic safety expressed plate torque value (Nm.) when is on rest position.
When electromagnet is excited [3], the armature plate [4] is attracted towards it, loading the torque springs [6].
The braking disk [5], coupled to the drive shaft [2], is then free to
turn around. When current is absent there’s no electromagnetic field, springs pushing the armature plate against the braking disk braking the drive shaft.
Adjustment of braking torque is obtained by acting on the yellow screws [7].
