Abstract: The present disclosure describes a two-stage method for estimating an angle offset of an angle sensor in a system comprising a permanent-magnet synchronous motor. An initial value for the estimated angle offset is first determined with a short-circuit test. Next, a torque of the motor may be controlled so that the motor is maintained at a zero speed. Minor adjustments are made to the value of the angle offset to find a minimum magnitude of stator current. A value at which the stator current is at its minimum is used as a final angle offset.

Abstract: The present disclosure describes a method and an inverter system for controlling a radial force of a rotor of a three-phase electric machine comprising four-pole stator windings with two separately-supplied, three-phase winding portions that are electrically in a two-fold rotational symmetry. The method and the inverter system control the rotation of the rotor with a four-pole main magnetic flux component generated to the four-pole stator windings and the radial force of the rotor with a two-pole auxiliary magnetic flux component generated to the four-pole stator windings. The four-pole main magnetic flux is generated by controlling voltages supplied to the three-phase winding portions, and the auxiliary magnetic flux component is generated by controlling a voltage difference between the voltages supplied to the three-phase winding portions.

Abstract: The present disclosure describes a load/unload control method for a compressor system with a rotating compressor connected to a pressure vessel. In the method, the present operating state can be monitored on the basis of a monitored/estimated electrical quantity of the compressor system. The method comprises an identification phase and an operational phase. In the identification phase, the compressor is operated at a constant rotational speed to generate two known pressures to the pressure vessel. At least one electrical quantity is monitored, and values of the electrical quantity corresponding to the pressure limits are stored. In the operational phase, reaching of a pressure limit may then be detected by comparing the present value of the monitored electrical quantity to the stored values.
