What is the SER electromagnetic clutch?
The SER electromagnetic clutch play a crucial role in transmitting motion in a variety of industrial and automotive applications.
Operation of the SER electromagnetic clutch
The SER electromagnetic clutch is a device that operates by the application of an electric current.
Its operation is based on the interaction between an inductor core with a coil and a rotor with friction material, together with an armature assembly comprising an armature disc and a spring-membrane.
When DC voltage is applied to the coil, a magnetic field is generated which attracts the armature to the friction-lined rotor, allowing the transmission of motion.
In the absence of current, the diaphragm spring retracts the armature, disengaging the clutch and stopping the transmission of motion.
SER electromagnetic clutch constructions
The SER electromagnetic clutch offers three different types of construction, each designed to suit different needs and applications.
- Construction 1.1: The SER clutch design 1.1 is the basic unit. It includes the inductor core with the rotor and bearing, as well as the armature with the spring-membrane. This configuration is mounted directly on a pulley or sprocket, which makes it suitable for simple applications requiring a reliable and compact clutch.
- Construction 1.2: The 1.2 construction of the SER clutch adds a pulley or sprocket carrier bushing to the basic configuration. This provides greater versatility, as the clutch can be mated to a variety of components, making it easy to adapt to different transmission systems. The diaphragm spring and armature remain essential components for operation.
- Construction 1.3: The 1.3 construction of the SER electromagnetic clutch introduces an aluminium hub instead of a pulley or pinion hub. This design allows the clutch to be mounted on a different shaft, which further expands the installation options. The inductor core with rotor and bearing remain present, as does the armature with the spring-membrane, ensuring reliable performance.
