A massaging device contains the body encompassing the shaft with the massaging appliance mounted on bearings and two-pole permanent magnet. Two similar coils of winding installed concentrically to the shaft are shifted one relative to another around the longitudinal axis of the shaft. The second permanent magnet is located between the coils. The electrical axes of the coils as well as the magnetic axes of the magnets are oriented in normal mode relative to the shaft. The device also contains the direct current power supply, semiconductor inverter and control unit of amplitude and frequency of inverter. The output of the control unit is connected to the control input of inverter. The output of inverter is connected to the electric winding. The power supply is connected to the supply input of inverter. |
