Coreless permanent magnetic motors

The coreless permanent magnetic tombarthite motor founds the future of the motor by changing the traditional silicon steel sheet and the winding stator structure with the technologies of free iron core, free shaft and Non magnetic damping permanent magnetic tombarthite technology
Characteristics of structure 
    1,the ratio of high power and the torque can be greatly promoted with the technology of axial magnetic field structure.

    2,High precision die casting molding and high density polymer are introduced to reduce the copper loss during winding.
    3,reducing of iron loss and the driven power are both due to the abandon of the silicon steel sheet stator.

Advantages 
    1,efficient and power saving: compared to the traditional motors, the coreless permanent magnetic tombarthite motor may save around 80% when non-loaded. Energy saving can be up to 30% or more in some unbalanced load conditions systematically.
    2,simple and tiny framework, only 1/3~2/3 weight of that of the ordinary ones.
    3,source saving: compared to the traditional motors, the coreless permanent magnetic tombarthite motor saves 80% steel, 100% silicon steel sheet and 50% copper at least.
    4,wide speed range and easy to adjust. The efficient characteristic can be easily made in the wide range and the accuracy is pretty high.
    5, stability, the temperature of the motor is low and the little ones can run without the electrical fan.

Below are the infomation of magnetic coupling from SUNSHINE

Our Strength:  Sunshine Couplings have ability to make custom design to achieve Maximum working torque with fewer magnets, minimum sizes to lower cost while achieving a given torque. 

Sunshine permanent magnetic couplings optimally comply with the increasing environmental safety protection awareness. High torques can be transmitted wear-free through the vessel walls and are prevented from damage. If the maximum torque is exceeded, the torque transmission will be interrupted so that overload protection is always guaranteed. 

The well proven compact and high-performance magnetic couplings from Sunshine Magnet apply rare earth magnets with excellent magnetic capacities. 

A significant performance advantage of the SUNSHINE magnetic coupling is the freedom from wear in contrast to dynamic seals. Being a competitive advantage for our customers, this ensures worldwide expanding application areas for SUNSHINE COUPLING, predominantly in the chemical and plastics industries.

Temperature : The Coupling Magnet has a maximum operating temperature of +180 deg C with ferrite, +550 deg C with Alnico and +200 deg C with NdFeB, 350 deg C with SmCo Magnet.

Applications:

• Widely used in magneic drive pumps, autoclaves, mixers vaccum sealing transmission machinery industries and ect.
