Abstract
The article examines a magnetic reducing gear, the stator winding of which receives power in the mode of a valve machine. In the absence of this supply, the electric motor can be started-up in no-load mode. To significantly reduce the power of the magnetic reducing gear frequency converter compared to the power of the adjustable electric motor, it is necessary to make the number of the rotor's pairs of poles with permanent magnets of a magnetic reducing gear large enough. In this case, the design of arranging the magnets in radial grooves is the most adequate, ensuring the concentration of fluxes per pole in the air gaps. The stator winding of such a magnetic reducing gear will be low-pole. When manufacturing a magnetic reducing gear, it is possible to use a stator magnetic core of a serial asynchronous machine together with its regular winding. The electromagnetic moments of the magnetic gearbox rotors are a consequence of the presence of a stator electromagnetic moment. The stator's current frequency is represented by two components, of which the first is defined from the state equations and the second is a constant forming an additional channel of functional influence. The speed of rotation of the gear shafts can be adjusted by changing the specified constant and the input voltage of the frequency converter. The equations of the magnetic reducer state describing its functional modes were solved by means of the Mathcad mathematical program.
