Description

LWN2660-6E 3BHL000986P7000: Product Overview
The LWN2660-6E 3BHL000986P7000 is a low voltage AC motor within ABB’s LWN series, designed for heavy-duty industrial drive applications requiring reliable power delivery and energy efficiency. As a core component in automation systems—such as oil refining, chemical processing, and power generation—it serves as the prime mover for pumps, fans, compressors, and conveyors, converting electrical energy into mechanical torque with minimal losses. Its 6-pole design (990 rpm) optimizes performance in medium-speed applications, balancing torque density and efficiency for continuous operation.
Functionally, the motor integrates with ABB’s variable frequency drives (VFDs) via Modbus TCP or Profibus DP, enabling dynamic speed adjustment to match process demands (e.g., variable flow in pipelines). It features a robust cast iron frame, high-quality bearings, and corrosion-resistant coatings, ensuring durability in harsh environments (dust, moisture, chemicals). As part of the LWN series, the LWN2660-6E 3BHL000986P7000 leverages ABB’s motor technology platform, offering compatibility with global efficiency standards (IE3), uniform mounting dimensions (IEC 60072), and seamless integration with ABB 800xA DCS for remote monitoring. This design simplifies system design, reduces lifecycle costs, and supports sustainability goals through energy savings.

Core Features & Customer Value​
IE3 Premium Efficiency Reduces Energy Costs: The LWN2660-6E 3BHL000986P7000 meets IE3 efficiency standards, delivering up to 5% higher energy savings than IE2 motors. For a chemical plant’s cooling water pump (8,000 operating hours/year), this translates to 0.10/kWh, with a payback period of <2 years.
Robust Design for Harsh Industrial Environments: With an IP55 protection rating and F-class insulation, the motor resists dust ingress and water jets, while withstanding high ambient temperatures (+40°C). In a steel mill’s dust-laden conveyor system, this minimizes bearing failures and extends maintenance intervals by 30%.
VFD Compatibility Enables Process Optimization: Seamless integration with ABB VFDs (e.g., ACS880) allows speed control to match variable loads (e.g., fan airflow adjustment in power plant boilers). This reduces mechanical stress on impellers and belts, cutting wear-and-tear costs by 20%.
Standardized Mounting Simplifies Retrofits: Adherence to IEC 60072 dimensions ensures drop-in replacement for legacy motors (e.g., Siemens 1LA8 series) without modifying couplings or foundations. For a water treatment plant upgrading its pump drives, this avoids $50,000 in civil engineering costs.
SIL 2 Certification for Safety-Critical Applications: When paired with ABB safety VFDs, the motor meets SIL 2 (IEC 61508) requirements for emergency shutdown (ESD) scenarios. For oil refinery pump systems, this ensures safe torque removal during leaks, preventing spills.
Typical Applications​
The LWN2660-6E 3BHL000986P7000 is deployed in industrial drive systems requiring medium-speed, high-torque power. In a petroleum refinery’s crude oil transfer pump station, it drives a 260kW centrifugal pump at 990 rpm, with VFD speed adjustment maintaining pipeline pressure (10-15 bar). The IP55 rating withstands outdoor coastal humidity, while IE3 efficiency reduces annual energy use by 450,000 kWh.
At a chemical plant’s ventilation system, the motor powers a 12m diameter exhaust fan, adjusting speed via ABB ACS880 VFD to match toxic gas concentrations. Its F-class insulation handles intermittent overloads during emergency purges, ensuring compliance with EPA emission standards.
In a municipal wastewater treatment plant, the LWN2660-6E 3BHL000986P7000 drives an activated sludge mixer at 990 rpm. The B3 foot mounting fits existing concrete foundations, and SIL 2 certification validates use in flood-level safety interlocks.
