1. SCF Supercritical generator

Hummer’s 100kW pitch turbine generator adopts SCF supercritical technology which won a gold award in the 37th Salon Eureka in Brussels. This technology significantly reduces generator’s weight and size down to 20% to 30% of the traditional one, and the production efficiency is 10% to 30% higher. This ensures that the generator functions perfectly in small wind condition.  

2. NSK bearings

Hummer 100kW turbine adopts the NSK bearings which are produced by the renowned bearing manufacturer in the world, with the perfect internal geometric structure, known for its life-time endurance and reliable quality. As well as enabling smooth and quiet rotation, they also perform an important function by taking on the motor's load.

3. PLC integrated with Siemens module

Hummer 100kW turbine controlling system adopts the smart touch-screen PLC (Programmable Logic Controller) which is integrated with Siemens controlling unit. The PLC will alarm and adjust the abnormal running status of the wind turbine automatically both timely and efficiently. Siemens module offers high reliability to our PLC and its customers worldwide can testify for that.
