摘　　要：本文首先对作为仪表元件的力矩电机的工作原理进行分析,说明本文所论的力矩电机是一种将电流转换为力矩的转换器,又是一种动铁式电磁驱动器。进而对力矩电机的传递函数进行了推导,并得到结果:力矩马达是一惯性加积分环节。对自制力矩电机的机械特性和调节特性进行了测试。试制和实测表明,转角力矩式电动机除机械特性和调节特性具有线性或近似线性的关系外,因其无噪声、低功耗、无自身温升及抗震性能好而获得了较广泛的应用。At first, this paper has analysed fundamental theory of torque motor using instrumentation component, showing that torque [motor is described in the paper is a translator that electric current turn into torque, is a movingiron type electro-magnetic driver.Next, transfer function of torque motor is developed in the paper, reach the conclusion that torque motor is a inertial plus integral link.It is tested that mechanical characteristics and regulating characteristics of the self-made torque motor. Trial manufacture and real test showing that the torque motor is used widely, because it has no noise, no temperature rise, low power loss, and high shake proof performance.
