GEM specializes in elements such as stators and rotors for high velocity motors with pride itself on providing its clients with products known for their high speed, high efficiency, and high power-density.

GEM stators and rotors have been developed through their own research and development institute. Currently, a wide array of products is on offer, ranging in capacity from 1kW to 400kW and in rotation speed from 10,000 to 100,000rpm. They can have various applications, such as high-frequency spindles and turbo blowers, turbo compressors, and EV.

As a pioneer in this field in Korea, GEM exerted its efforts toward localizing motor components that have traditionally been procured from foreign makers. Gem possesses many experts with experience working in high-profile, high-speed motor electronics and machinery fields. As a result, it can provide high-speed, highly efficient, high-capacity rotary systems that are exquisitely tailored to meet the needs of individual customers.

GEM succeeded in being the sole supplier of high-speed motor elements in 2010 by mass-producing elements with high-frequency spindles. Its innovative product-development and consulting services are reputed to more than exceed customer expectations.

With international patents for its products, GEM engages in producing highly efficient, large-sized products for electric vehicles as well as ultra-compact ones (with a rotational speed of 100,000rpm). At the moment, there are 30 different types of products for mass production.

GEM is capable of meeting any kind of customer order through providing with a full range of production consulting from the design phase to the final product's application, and it can satisfy customers' changing requirements and offer fast and optimum solutions for any difficult problems encountered by customers.

A2P-S48 GEM 2-pole Product

 CU: The bars and end-rings in the rotor are made from copper to ensure high motor efficiency. This also allows for decreased vibrations from rotation as the shaft is thicker than those used in aluminum rotors.
 AL: The bars and end-rings in the rotor are made from aluminum, which provides an excellent balance between price and performance.
 LD: This stator is dipped into the insulation vanish. It is our most common model, which is suitable for general spindle motors.
 HD: This copper coil of the stator is filled with special resin which helps to decrease the temperature of the coils.

If you are looking for stators and rotors for high velocity motors, you can find them at GEM.
