Description

GE 5KS42HN4056A 3-Phase AC Induction Motor

Product Dimensions：

The GE 5KS42HN4056A is a premium, high-efficiency industrial AC induction motor manufactured by General Electric (under the GE Industrial Motors or Wolong brand portfolio). It belongs to the Kinamatic™ or GCP/Severe Duty motor families, designed to deliver reliable mechanical power under harsh operating conditions.

Product Detailed Description

The 5KS42HN4056A is a three-phase asynchronous motor featuring a rugged cast-iron construction. It is engineered to meet or exceed stringent industry standards (such as NEMA and IEEE) for severe-duty applications. The “KS” designation typically points to an enclosure designed for dirty, damp, or corrosive environments, making it a staple in heavy industries like processing and manufacturing.

Product Parameters (Technical Specifications)

Note: Specific mechanical dimensions and exact horsepower ratings correspond to the NEMA frame designation embedded in the model code (420 series frame).

Product Advantages

• Severe Duty Construction: The all cast-iron construction resists corrosion, physical impacts, and structural twisting, ensuring a long operational life in hostile environments.
• Superior Thermal Management: Utilizing Class F insulation with a Class B temperature rise provides an extra thermal margin, protecting the motor windings from overheating during temporary overloads.
• High Efficiency: Designed to optimize energy consumption, reducing total cost of ownership (TCO) and meeting strict energy compliance standards.
• Advanced Ingress Protection: The TEFC design keeps moisture, dust, and airborne contaminants out of the internal electrical components.

Important Considerations & Precautions

• Shaft Alignment: Precise alignment between the motor shaft and the driven load (pump, fan, gearbox) is critical. Misalignment causes premature bearing failure and excessive vibration.
• VFD Operation: If this motor is driven by a Variable Frequency Drive (VFD), ensure it is rated as “Inverter Duty” and check for proper grounding (e.g., shaft grounding rings) to prevent electrical bearing damage.
• Lubrication: Follow the manufacturer’s intervals and specification chart for regreasing the bearings. Over-greasing can destroy the bearing seals and damage the windings.
• Terminal Voltage: Ensure the supplied line voltage matches the nameplate rating within \pm10\% to prevent winding degradation or starting failures.

Product Applications

The GE 5KS42HN4056A is found in heavy-duty industrial infrastructure:

• Pumps: Driving large centrifugal or positive displacement pumps in water treatment and chemical processing.
• Fans & Blowers: Powering industrial ventilation systems and cooling tower fans.
• Compressors: Operating continuous-duty air or gas compressors.
• Conveyors & Crushers: Providing the raw torque needed for material handling lines in mining and aggregate facilities.
