Theory of Operation of a Magnetic Torque Coupler

In the simplest form, magnets are able to exert a force over a distance. Whether by inducing a field in a ferromagnetic material or interacting with another magnet, a magnet can exert a force without touching. The magnet’s magnetic field is the mechanism for this non-contact force…

Implementation Considerations for Synchronous Magnetic Torque Couplers (Geometric Misalignment)

When selecting a style of Synchronous Magnetic Torque Coupler, one must consider the type and how the coupler will be integrated to ensure a trouble free performance. The style of coupler, Face-to-Face or Coaxial, will generally be dictated by the requirements of the application, but the ability to ensure correct radial, axial, or angular alignment will also need to be considered…

A Guide to Magnetic Linear Couplers

In this third Tech Talk article in a five-part series about Magnetic Torque and Magnetic Linear Couplers, we take a closer look at Magnetic Linear Couplers. Similar to a Magnetic Torque Coupler, a Magnetic Linear Coupler relies on the magnetic interaction between two coupler halves. As in the Torque Coupler, usually one half is the driver, and the other half is the follower. Linear Couplers are often simpler to design and to construct when compared to Torque Couplers because the movement is linear and non-rotational…

Types of Magnetic Torque Couplers – Face-to-Face & Coaxial

In this second post of a series exploring magnetic couplers, we examine two different types of the commonly used “synchronous” style of magnetic torque coupler, which is a style of coupler in which the coupler’s output shaft speed equals the input shaft speed. The two primary versions of the synchronous style torque couplers that we will be discussing are the “Face-to-Face” type and the “Coaxial” type.

An Overview of Magnetic Torque and Linear Couplers

This Tech Talk article is the first in what will become a five-part series of articles focusing on Magnetic Torque and Magnetic Linear Couplers. Magnetic Torque and Magnetic Linear Couplers are used for applications where non-mechanical contact is desired. They are employed in high-vibration applications or where two operating environments need to be separated.
