Description
What is the SEE electromagnetic clutch?
The SEE electromagnetic clutch is an essential component in power transmission systems, as they allow the controlled coupling and decoupling of two mechanical elements.
Operation of the SEE electromagnetic clutch
The SEE electromagnetic clutch is based on the principle of magnetic attraction to transmit motion between two components. Its operation is relatively simple but highly efficient.
It consists of three main parts: the inductor core with the corresponding coil, the rotor with incorporated friction material and the armature assembly.
When a DC voltage is applied to the coil, a magnetic field is generated across the friction-lined rotor. This magnetic field attracts the armature assembly, consisting of the armature disc and a spring-membrane.
This magnetic attraction is what allows the transmission of motion between the rotor and the armature assembly. In other words, the clutch engages and transmits motion when it receives current.
On the other hand, when no current is supplied to the coil, the spring-membrane retracts the armature assembly. This means that the clutch disengages, ceasing to transmit motion between the parts.
This controlled coupling and decoupling capability is especially useful in applications where precise synchronisation or quick disconnection of two components is required.
SEE electromagnetic clutch constructions
The SEE electromagnetic clutch offers three different types of constructions, each designed to suit different needs and applications.
- Construction 1.1: In manufacturing and assembly equipment, where precise control of the clutch and clutch release is required, these devices ensure consistent performance.
- Construction 1.2: This is the basic clutch unit. It includes the armature, the rotor and the armature assembly with the spring-membrane. This construction is ideal for mounting directly onto a pulley or sprocket, providing a simple and efficient solution.
- Construction 1.3: In the third construction, in addition to the basic elements, an aluminium hub is incorporated. This option is ideal when the clutch needs to be mounted on another shaft. The inclusion of the aluminium bushing ensures a solid and reliable coupling.
