摘要:
为了提升永磁同步电机整机输出功率,同时降低每相绕组的电压、电流等级,通常采用多相或多单元设计。以一台五单元直驱式低速大扭矩永磁同步电动机为对象,建立了多单元永磁同步电机的电压、转矩方程。在部分单元电机容错运行时,采用磁共能法推导出单元电机不同数量、位置时的转矩波动解析表达式,并给出采用注入3次谐波电流抑制转矩波动的方法。数值分析和试验结果表明,所建立的多单元电机数学模型准确,转矩波动抑制方法有效,在部分单元电机额定状态运行时,转矩波动最多可降低3.5%,该数学模型和转矩波动公式及其抑制方法均可有条件推广至不同单元数量的电机分析之中。
Abstract:
In order to enhance the output power of permanent magnet synchronous motor(PMSM) and reduce voltage and current level of the per phase winding,the multi-phase or multi-unit windings have been often used in the superpower machine designs.Looking a five-unit direct drive low-speed and high-torque PMSM as research object,the multi-unit PMSM voltage and electromagnetic torque equations were established.Nevertheless,when only part of units were operating,analytical expressions of torque ripple produc...
