Standard Type Permanent Magnet Eddy Current Transmission
Standard Type Pernmanent Magnet Eddy Current Transmission mainly include the copper rotor,permanent magnet rotor.Generally copper rotor (Steel rotor with copper ring)connect with motor shaft,
permanent magnet rotor (aluminum rotor with permanent magnets)connect with load shaft.There is only a air-gap between copper rotor and permanet magnet rotor without mechanical connection for
transmissing the torque.When the motor rotates,the copper ring of copper rotor cut the magnetic field lines of permanent magnet,generate inductive eddy current and creates a magnetic field in copper rotor,thereby transmitting torque accross the air-gap.Allowed adjust the air-gap within a certain range to achieve the required torque transmission and speed delivery requirements.
Few day-maintenance,low operation cost,almost maintenance-free products Accept misalignment,centration error 5mm (max),angular error 2.5(max)。
With overload protection,increase overall system reliability,eliminate the damagement of system for overload
Improve the motor starting capability and come ture the motor soft start /stop.And,reduce shock and vibration,coordinate between multi-machine-driven load distribution.
Extend the life of the transmission system components.
Simple structure,small size,easy to install,adapt to work in harsh conditions.
Allowed adjusted the air-gap to achieve the required torque transmission and speed delivery
requirements.

标准型永磁涡流联轴器由铜转子、永磁转子二个部分组成。
铜转子(带铜环的钢制转子)与电机
轴连接,永磁转子(带永磁材料的铝制转子)与工作机的轴连接，铜转子和永磁转子之间有空气间隙(称为气隙),没有传递扭矩的机械连接。
在电机转动时,铜转子的铜环上在切割永磁体的磁力线时产生感应涡电流，而感应涡电流的磁场与永磁体的磁场之间的作用力实现了电机与工作机之间的扭矩传递。
可以在一定范围内调整气隙（3~6mm),达到所需的扭矩传递和速度传递要求。
日常维护工作量小，为免维护产品，运行成本低。
允许较大的安装误差（允许最大的对中误差可为5mm、角度误差可为2.5°。
具有过载保护功能，从而提高了整个系统的可靠性，完全消除了系统因过载而导致的损坏。
提高电机的启动能力，实现电机的软启动/停止。
减少冲击和振动。
协调多机驱动的负荷分配。
延长传动系统中各零部件的使用寿命。
结构简单，体积小，安装方便，适应在恶劣的工况下工作。
可以通过气隙的调整，达到所需的扭矩传递和速度传递要求。
适合各种特殊的轴径或安装尺寸要求。
