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
An air-gap between copper rotor and permanent magnet rotor without mechanical connection for
Trans missing 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 across 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 amazement of system for
Overload
Improve the motor starting capability and come true the motor soft start / stop. And, reduce shock and
Vibration, coordinate between multi-machine-driven load distributions.
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.
Supply a variety of special shaft or installation size.
