摘要：
Determination of field winding parameters is the key to solve the design problem of magnetic functional integrated DC motor drive. A method for calculating the field winding parameters of magnetic functional integrated DC motor drive based on Buck-Boost converter is proposed. The mathematical model of the system and the expression of the constraint conditions for the drive circuit were derived. By overlapping the mechanical characteristic surface and the constraint condition surface of the motor in three-dimensional space, the analytical expression of the boundary curve of the operational region can be obtained. Then the range of field winding parameters at a given working point was calculated. With this method, the parameters of field winding of magnetic functional integrated DC motor were calculated, and the prototype was designed and manufactured, and then compared with the traditional DC motor drive. The results show that, comparing with the traditional method, the magnetic functional integrated drive system has higher efficiency and lower copper loss. At the same time, the magnetic functional integrated drive system saves an additional inductor, which improves the power density of the motor drive system and reduces weight, volume and cost of the system. © 2023 Editorial Department of Electric Machines and Control.
