COMBINED TORGUE AND BODY SHIFT MOTOR Russian patent published in 2003 - IPC

FIELD: instrument engineering, applicable in devices containing magnetic or electratic body suspension systems (for example, rotating rotor), in particular in contactless gyroscopes and magnetic bearings. SUBSTANCE: the motor has a bridge circuit, whose two arms are made up of sources of forward and inverted voltages, the other two arms are made up of load-bearing elements. Connected to the circuit diagonal is the output of the amplifier-converting unit and the current transmitter, connected to the first output of the subtracting device, whose second output is connected to the output of the amplifier - converting unit via the amplitude regulator and integrator. The unit first input is connected to one of the sources of reference voltage, the second input of unit is connected to the source of the signal proportional to the torque applied to the body, and the output of the subtracting device serves as a source of the signal on angular (or translation) displacement of the body. EFFECT: enhanced precision of measurement at a simplified circuit fed from a reference source of AC voltage of the same frequency. 3 dwg _
