The utility model relates to a permanent magnet speed governor with fixed magnetic gap, including a rotor connected with an input shaft, a magnetic rotor and an armature rotor connected to the inner and outer sides of the rotor circumference, which are connected to the inner and outer sides of the rotor circumference. The rotor includes a winding coil A distributed along the circumferential circumference of the rotor and the permanent magnetic field along the circumference of the outer circumference. The magnetic rotor includes the permanent magnet A along its circumferential circumferential direction. The armature rotor includes the winding coil B along its circumferential circumferential direction, and the winding coil B is in the same polarity as the winding coil A, and the two winding coils are connected with the control system for the current adjustment, and the rotor and the armature rotor are fitted with a slip ring. The utility model can greatly reduce the loss of rotor heating due to the use of armature winding, and by adopting the current control principle, the speed control reaction of the governor can be fast, flexible and stable, thus the transmission efficiency of the permanent magnet speed governor is greatly improved and the application range is wider.

一种固定磁隙的永磁调速器

技术介绍
永磁调速器是通过永磁体的磁力耦合调速,实现电动机和负载的软磁连接,无任何影响电网的谐波产生,可靠性高,并可在高温、低温、潮湿、肮脏、易燃易爆、电压不稳及雷电等各种恶劣环境下工作,大幅减轻机械振动,广泛应用于电力、钢铁、冶金、石化,造纸、市政、舰船、灌溉及采矿等行业。而目前常用的永磁调速器均是通过调整气隙来实现转速调整的,磁路调节器的功率消耗大,且存在扭矩传递能力差、装配难度高、浪费大量稀土资源等缺点。为解决上述问题,专利CN2015108084423提出一种固定磁隙的永磁调速器,从保持磁隙不变、改变磁力线的数量入手去设计的永磁调速器,通过控制永磁转子对外展现的磁性大小,从而达到改变转矩的目的。由于采用的是涡流感应原理,能量转换效率低、发热量大,滑差时产生大量的热量。采用磁路调节系统,调节速度慢,反应不灵敏。
