High level of slip-free torque transmission with the most compact mounting dimensions
Electromagnetic tooth clutches are electromagnetically actuated, spur geared clutches with a slip-ring-free coil on bearings.
Mode of operation
For the effect of the magnetic field on the clutch procedure, a distinction is made between two functional systems:
Power to engage: The magnetic force induced in the coil via a DC current generates the axial clutch force.
Power to release: The magnetic force induced in the coil via a DC current overcomes the clutch force generated via springs, thereby opening the clutch.
- High torques in the tightest of installation spaces
- Wide range of geometry of the gear teeth and engagement positions
- Can also be used in extreme temperatures
- Anti-magnetic clutch toothing for optimal magnetic flux
The electromagnetic toothed holding brake is actuated electromagnetically. The crown toothing can be designed differently for various application scenarios.
By applying a DC voltage to the coil, a magnetic force is generated between the magnet housing and armature plate. This pulls the armature plate against the force of the membranes in the direction of the stator. The crown toothing engages upon relative motion.
Once the DC voltage is no longer present, the magnetic field collapses and the restoring force of the membranes causes the crown toothing of the armature plate to disengage. This causes the torque transmission to be interrupted and the armature plate is held in the idling position by the membranes.
