The yaw system of Mw class wind turbine can make the impeller align with the wind direction by rotating the engine room to achieve the maximum utilization of wind energy. Through the optimization control strategy of dynamic and static processes, flexible start and stop, clearance elimination between teeth and other functions, the unit can achieve less vibration and wear, and achieve the win-win goal of long life and low cost. system composition: The system consists of yaw frequency converter, br

The construction elevator is an indispensable dual-use transportation equipment for people and goods in the construction. Now it has been controlled by the frequency conversion scheme, and the construction elevator is mainly used at present.

Provide two energy storage media, super capacitor or lithium battery

The pitch system of Mw wind turbine can control the absorption of wind energy by the impeller by adjusting the windward angle of the blade, so as to realize the power regulation, startup and shutdown of the fan. Under special circumstances, the pitch system can independently control the blades to ensure the safe shutdown of the unit. System composition: core components of pitch system: servo driver, motor, backup power supply
