Electromagnetic Disk-type Clutches

Aplicaciones

The types with rotating electromagnets have the simplest design and are the cheapest ones. They have an electromagnetic cup, which has on the outside a collector ring on one side, and a disk holding cover and armature on the other. It is good practice not to exceed 18 m/s rotational speed under tension; also, if only one collector ring is present, it is necessary to ground the clutch through the machinery, in order to close circuit. Since the fixed−electromagnet series has no collector ring, there are no brush sparking phenomena to contend with, thus providing greater operational safety and precision. The rear end of the non−magnetic center hub supports the rotor and cup−holder bearings and the toothed front−end guides and actuates the disks and armature. Disk−wear take−up in both types of clutches is automatic. Thus, no disk−wear adjustment intervention is required.
