FIELD: electricity.
SUBSTANCE: method for forming positive rigidity of linkage characteristic of solenoid involves supply of sum of direct and alternating voltages to solenoid through controlled resistance on which variable component of voltage is rectified, filtered and supplied to control input of this resistance. As sum of direct and alternating voltages, there used is output voltage of power rectifier with pulsation. Method allows producing simple (available for wind range of industrial and household items) magnetic levitations - bearings.
EFFECT: simplifying sensor-free method for forming positive rigidity of linkage characteristic.
