Resistant to 200℃ High Temperature Permanent Magnet Synchronous Motor Design
Aviation,aerospace and other fields and large boilers,deep well exploration and other high temperature environment on the motor high temperature requirements.Because the position feedback elements such as Hall sensor and photoelectric sensor are unstable in collecting signals at high temperature,a new process is adopted to improve the high temperature resistance of the main heating element of the motor,the armature,and the high temperature resistant rotary transformer is used as the position feedback sensor,taking 28 V and 10 000 r·min-1 motor as an example.Thus,the problem of high temperature instability of Hall sensor is solved,and the long-term working temperature of the motor is raised to 200℃.The load motor is calibrated at normal temperature,and two high temperature motors are used for towing test at high temperature.The performance of the designed high temperature motor is indirectly tested by current and motor back electromotive force waveform.
