Scope of Application
The YE4 series is suitable for driving a wide variety of general-purpose industrial machinery, including:
Compressors
Ventilators / Fans
Water pumps (including centrifugal, multistage, and boiler feed pumps)
Machine tools
Conveyors and transportation machinery
Blowers
Coal mills
Rolling mills
Hoisting and crane equipment
Crushers
Belt conveyors
These motors serve as prime movers in diverse industrial sectors such as:
Mining
Machinery manufacturing
Petrochemical
Power plants
Steel mills
For applications involving high inertia loads (e.g., blowers, mills, crushers, belt conveyors) or frequent starting, special design considerations may be required. Please provide relevant technical data at the time of ordering, and a technical agreement will be signed to ensure reliable motor operation.
