Abstract

The invention relates to the field of circuit control, in particular to a motor control method. According to the motor control method provided by the invention, a plurality of discrete phase windings of a controlled motor are individually controlled; and the current magnitude and direction of each phase winding are adjusted to or maintained at target values, so that the controlled motor reaches the target characteristics. Various phase windings do not need to be connected into a star-like structure or a closed loop; and the phase windings do not need to be switched back and forth between the star-like structure and the closed loop, so that the targets of simplifying the circuit and improving the system stability are achieved. Compared with the condition that various phase windings in the motor are connected into a specific topological structure in the prior art, control on the motor by the motor control system and method provided by the invention is more flexible; and the circuit characteristics which can only be achieved by connecting the phase windings into the specific topological structure in the prior art are completely achieved under the conditions of not changing the relative positions of the phase windings in the controlled motor and not connecting the phase windings.

Description

technical field [0001] The invention relates to the field of circuit control, in particular to a motor control method. Background technique [0002] In motor control, in view of the multi-phase windings of the controlled motor, it is often necessary to connect the multi-phase windings in the controlled motor to a special circuit topology (such as star structure, end-to-end closed Ring structure), so that the controlled motor can realize the corresponding characteristics, and different characteristics need to be realized by connecting the phase windings to different circuit topologies. In practical applications, in order to achieve different characteristics, the controlled motor will be multi Each phase winding is connected to the corresponding topology (such as star structure or closed ring structure), and when the demand for circuit characteristics is switched, it is necessary to switch the circuit connection mode of multiple loads; this requires additional Switching circu...
