What is a magnetic coupling used for?
A magnetic coupling can be used to transfer power to centrifugal pumps. It consists of a primary part which is rigidly connected to the motor shaft, and a secondary part which is arranged on a shaft (see Pump shaft) together with the impeller.
What is a magnetic shaft?
Magnetic couplings are shaft couplings that use a magnetic field instead of a physical mechanical connection to transmit torque from one shaft to another. They are non-contact and utilize attraction and repulsion of the magnetic poles to transmit rotational power.
What are the two types of magnetic couplings?
We offer three types of couplings: synchronous, eddy, and hysteresis. A magnetic coupling is a device that is capable of transmitting force through space without physical contact. Attractive and repulsive magnetic forces are harnessed to perform work in either a linear or rotary fashion.
What is magnetically coupled circuit?
Magnetic coupling occurs, when there is no physical connection between two coils (or inductors). This coupling can be of either aiding type or opposing type. It is based on whether the current enters at the dotted terminal or leaves from the dotted terminal.
What is magnetic exchange coupling?
➢ Magnetic Exchange Coupling Magnetically dilute substances simply refer to the magnetic materials in which individual paramagnetic centers cannot interact with each other due to a large distance of separation.
What factors affect magnetic coupling?
The degree to which electronic equipment may be affected by the electromagnetic disturbances in the environment depends on many factors but is primarily dependent on: a) the coupling between the equipment, b) the magnitude of the external source, and c) the sensitivity of the internal electronics.
What is meant by coefficient of magnetic coupling?
The Coefficient of coupling can be defined as the fraction of the magnetic flux produced by the current in one coil that links with the other coil. It is represented by the symbol (k) and the amount of coupling between two inductively coupled coils is expressed in terms of the coefficient of coupling.
What is series and parallel magnetic circuit?
In a series circuit, the same amount of current flows through all the components placed in it. On the other hand, in parallel circuits, the components are placed in parallel with each other due to which the circuit splits the current flow.
What is interlayer exchange coupling?
Interlayer exchange coupling between magnetic layers mediated by a non-magnetic spacer has essentially the same physical origin as the RKKY coupling between magnetic impurities in a non-magnetic host.
Why does spin crossover happen?
Spin Crossover (SCO) is a phenomenon that occurs in some metal complexes wherein the spin state of the complex changes due to an external stimulus. The stimulus include temperature, pressure, Spin crossover is sometimes referred to as spin transition or spin equilibrium behavior.
What is magnetic drive centrifugal pump?
A magnetic drive pump uses a balanced magnetic field to create the rotation of the fluid impeller. Unlike a traditional centrifugal pump which has a direct drive connection between impeller and motor, a mag-drive pump eliminates the direct drive mechanism and replaces it with a magnetic field.
What is Mag drive?
Mag-drive pumps are a design of magnetically-driven chemical-process pump which eliminate the need for shaft sealing. This greatly reduces the initial cost of the pump as well as day-to-day operational costs as there aren’t any mechanical seals, seal-fluid pots, or cooling lines fitted.
What is significance of coefficient of coupling?
Definition of ‘coupling coefficient’ The coupling coefficient of a pair of coils is a measure of the magnetic effect passing between them. It is important for a balancer coil for cold-cathode fluorescent lamps to have a high coupling coefficient between coils.
What is a a magnetic coupling?
A magnetic coupling is a coupling that transfers torque from one shaft to another, but using a magnetic field rather than a physical mechanical connection.

What are the torque and bore sizes of Magnetic shaft couplings?
Torque ranging from 2.66 in-lbs. to 1610 in-lbs. (0.3 Nm to 182 Nm) Bore sizes range from 0.325” to 2.16” (8mm to 55mm) Miki Pulley offers magnetic shaft couplings in four styles to meet your requirements.
What is a propeller shaft?
The propeller shaft is a component used for transmitting mechanical power, torque, and rotation. These shafts as also known as driveshaft, driving shaft, tail shaft, or Cardan shaft. The driveshaft is used to transfer torque between components that cannot be connected directly because of distance or the need to allow relative motion between them.
