ABB 7BECR9758TR-4 Severe Duty Motor - CSA EEV
Part Number: 7BECR9758TR-4
Quick Summary
ABB 7BECR9758TR-4 Severe Duty Motor is engineered to deliver reliable, high-torque performance for crushers and heavy conveyors in mining and processing plants. In demanding environments, downtime and unexpected motor failures erode productivity and escalate maintenance costs. This model addresses that by combining a TEFC enclosure, rugged bearings, and a robust 8-pole frame with a 900 rpm synchronous speed to withstand continuous operation. It carries Premium Efficiency and CSA EEV certifications, aligning with energy codes and safety standards while reducing energy waste. The motor integrates seamlessly with 3-phase, 60 Hz, 460 V systems and offers a common 444T frame for straightforward retrofits. For buyers, the result is lower total cost of ownership and greater plant uptime through reliable, continuous operation.

Severe Duty construction with TEFC enclosure protects internal windings from dust, moisture, and harsh ambient conditions, reducing maintenance cycles and unplanned downtime; this translates to improved uptime for crushers and heavy conveyors in demanding mineral processing environments. The 75 HP, 460 V three-phase design delivers ample torque at startup, supporting Direct On Line starting while keeping electrical stress within design limits, which lowers soft-start equipment requirements and saves control cabinet space. Premium Efficiency (NEMA 12-12) reduces energy consumption by minimizing I2R losses, yielding measurable cost savings on long-running line drives and conveyor belts. An 8-pole configuration provides stable, high-torque operation at 900 r/min synchronous speed, offering predictable process control for milling and crushing cycles. Frame 444T and foot-mount configuration simplify installation and retrofit into existing plant footprints, while the NEMA Design Code A designation ensures compatibility with common industrial drives and safety standards. With a sturdy 61 in deep profile and 919 kg weight, this motor is engineered for robust alignment and long service life in continuous duty applications. Stocked at multiple warehouses and backed by a 0-day lead time policy, procurement teams can reduce procurement risk and accelerate project timelines. Units like this also benefit from CSA EEV certification and a 60 Hz, 460 V operating envelope, making it easier to meet regional compliance and energy mandates across North America.
