The synchronous motor control includes two standard instruction generators (8,9). A detector (12) determines the quantity of phase correction, whilst an adder (13) adds a positional angle for the rotor as well as a shift value. The synchronous motor control includes a standard instruction generator (8) for de-activating instructions relating to a first axis (d) and a second axis (q). This co-operates with a phase correction instruction. There is also a further standard instruction generator (9) transmitting standard instructions for the two axes (d & q). A detector (12) determines the quantity of phase correction, determining the shift value when the d-axis voltage instruction becomes null. An adder (13) adds a positional angle for the rotor as well as the shift value. A voltage converter (10) determines the three phase voltage instructions. |
