The article considers the possibility of changing the transmitting torque of a cylindrical magnetic coupling depending on the brand of a highly coercive permanent magnet: neodymium-iron-boron, samarium-cobalt and barium hexaferrite types Using the example of a standard magnetic coupling with a magnets diameter of 120 mm and an air gap of 5 mm between the magnetic coupling halves, the change in the transmitting torque of the magnetic coupling is shown to attain without changing its overall dimensions. Variation in the transmission torque of the magnetic coupling is possible by changing the shape, size and brand of permanent magnets, while leaving the same number of magnets in each of the half-coupling.
