Feature → Business Impact → Application: The 250HP, 2965RPM, 3PH, 50Hz ABB designation enables high-torque performance for heavy loads such as conveyors, mills, and crushers. The business impact is improved drive efficiency and consistent speed control, reducing energy waste and maintenance downtime in continuous operation. Application: suitable for US-based production lines requiring reliable high-power motors with fast stock availability. Feature → Shaft Grounding design reduces electrical noise and improves safety in shaft-driven systems, enabling easier grounding and protective measures in harsh environments. This translates to lower EMI, better motor protection, and fewer field wiring concerns, which is critical for bulk material handling and process lines. Application: steel, mining, and aggregate plants. Feature → Stocked At Warehouses and zero-day lead times improve project scheduling and reduce capital lockup; business impact is faster time-to-value and reduced safety stock. Application: new installations and parts replacement for ABB drives and controls. Feature → 250HP, 2965RPM, 3PH, 50HZ with 445TS frame provides standard industrial compatibility, easing installation, mounting, and alignment with existing mechanical libraries. Application: conveyor drives and heavy-duty processing lines in manufacturing. Feature → Product is shipped from multiple US warehouses; business impact is improved supplier resilience and shorter on-site setup. Application: plant expansions and newly commissioned lines. Feature → Large dimensions and weight indicate rugged construction and long service life with proper handling; business impact is reliability and lower long-term maintenance costs; Application: mine sites and heavy industrial facilities requiring durable equipment.

FAQs
For installation, verify the 50 Hz, three-phase power configuration matches your plant electrical system, and plan for the motor's footprint: 48 in length, 42 in width, and 52.5 in height with a 1697 lb weight. Use a rigid base, proper anchoring, and a grounded shaft grounding scheme. Confirm stock availability at local warehouses to minimize downtime and coordinate with gearbox or drive alignments during commissioning.
Key specs include 250HP, 2965RPM, three-phase 50Hz operation, and the 445TS frame. The motor carries a heavy-duty 1697 lb mass with external dimensions of approximately 48 in length, 42 in width, and 52.5 in height, enabling high torque for conveyors, mills, and crushers while maintaining stable speed under varying load conditions.
Yes. The 3PH, 50Hz configuration aligns with standard ABB drive architectures. It can integrate with common motor starters, VFDs, and protection schemes while maintaining grounding integrity and EMI considerations. Always check specific wiring diagrams, control option SKUs, and enclosure requirements in the ABB installation guides to ensure warranty and performance compliance.
Certification details such as CE, SIL, or IP ratings are not specified in the provided data. Confirm with ABB or your regional distributor for required approvals. In practice, ABB motors in this class typically meet regional electrical safety standards when configured for the target market and application, so validation with local authorities is recommended.
With zero-day lead times and stock across multiple US warehouses, project scheduling tightens and downtime decreases. ROI benefits include lower energy waste and reduced maintenance costs due to reliable, rugged construction. Quick replacements minimize production losses, while readily available spare units support proactive maintenance and longer equipment life.
