摘　　要：大型塔式起重机具有重载低速、轻载高速、慢就位的工作特点,其配套主电动机需具备宽调速比能力。文中以实际项目为例,介绍了一种宽调速比高紧凑型变频电动机研制方案,采用定转子槽配合和定子绕组方案以达到电磁设计指标,特殊的风道结构设计以保证散热。经过电动机性能测试验证实际性能达到设计指标,其转动惯量是常规电动机的60%。设计方案满足技术要求,具有实用性。Because of the working characteristics of a large tower cranes with heavy power at low speed,light load at high speed and slow positioning,the assembly motor is usually required with a wide speed regulation ratio.This paper introduces a new type of variable frequency motor with wide speed regulation ratio and high compacted through a project.The stator rotor slot fit,the stator winding schemes,the electromagnetic design specifications and the special air duct structure design to ensure heat dissipation,are analysised.Through a test verification,the actual performance reaches the design index and Its moment of inertia is 60%of that of conventional motors.The motor manufactured according the design scheme meets the technical requirements and is practical.
