N2 - Permanent magnetic synchronous motor (PMSM) with high speed, large torque and high power usually employs centralized high power, which increases the capacity of the transformer, and reduces the reliability of the system, so the paper proposes a scheme based on an autonomous decentralized architecture, in which the stator winding uses distributed network structure, each coil of the winding is controlled by a separate driving controller, to improve the fault tolerance of the driving system. The paper deduces the formula for PMSM vector coordinate transformation, and the formula for motor self-inductance and mutual-inductance, as well as the motor voltage and electromagnetic torque model in decentralized architecture, taking a 8-pole 12-slot PMSM as example, establishes the mathematical model of current compensation with constant motor instantaneous electromagnetic torque before and after one or all coils of phase A are failed, finally tests the correctness of the current compensation model by using finite element simulating analysis and concrete experiments.
