永磁调速器作为一种新型的调速节能设备,安装在电机与负载之间,采用全新的磁路耦合原理,通过调节气隙实现转速的控制。结合永磁耦合器与永磁电机的相关理论,设计了小功率永磁调速器,通过对磁路结构进行三维动态磁场仿真,分析磁路的形成机理、耦合原理。仿真结果表明这种磁路结构设计合理、可行。在此基础上,完成了磁路相关参数的优化设计。
As a new adjustable speed and energy conservation equipment, permanent magnetic driver is installed between motor and loads, uses the new magnetic circuit coupling principle, realizes the speed control through adjust air gap. Combined with the correlation theories of permanent magnetic coupler and permanent magnet motor,the low power permanent magnetic driver was designed , carried on the magnetic field dynamic simulation for this magnetic circuit,analyzed the forming mechanism and coupling principle of magnetic circuit. Simulation result has proved that the design of this magnetic circuit structure is reasonable and possible. On this basis, the optimization design of the magnetic circuit related parameter was completed.
