ABB 7B333B Motor - 0.75 HP, 60 Hz, 1-Phase, UR
Part Number: 7B333B
Quick Summary
ABB 7B333B motor is a compact 0.75 HP, single-phase drive designed for 115/230 V operation in small machine tools, grinders, buffers, and buffing stations. Engineers often struggle with finding a durable, space-efficient motor that fits a Totally Enclosed Non-Ventilated (TENV) enclosure and maintains reliable performance at 60 Hz. This model carries UL/CSA safety ratings and UR certification, with a Class B insulation and a 40 °C ambient rating, making it suitable for standard factory environments. Dual-voltage versatility, a foot-mounted base, and a predictable 3600 r/min speed help optimize installation planning and lifecycle costs for automation lines and workshops.

Feature → Business Impact → Application: Dual voltage 115/230 V reduces spare-parts inventory and simplifies wiring, enabling quick field upgrades without rewiring. This supports faster line changeovers in grinding and buffing stations, lowering downtime and improving overall equipment effectiveness. Feature → Application: 0.75 HP output at 60 Hz delivers sufficient torque for small machinery like grinders and buffers, enabling consistent finishes while keeping energy usage in check. Feature → Business Impact → Application: 2-pole, 3600 r/min design provides stable speed under continuous duty, reducing process variance in lathes and belt sanders. Feature → Installation Advantage: Foot-mounted, horizontal orientation with a steel frame and TENV enclosure allows easy retrofit into existing tool pages and safer operation in factory floors, even in 40 °C ambient conditions. Feature → Compliance and Maintenance: UL/CSA and UR certifications, finite insulation class (B), and a straightforward direct-on-line starting profile minimize regulatory risk and maintenance costs across the plant. Feature → Reliability and Availability: Stocked at multiple warehouses with 0 day lead time and flexible shipping, improving procurement resilience for critical spares in grinders and buffers lines.

FAQs
The 7B333B motor supports 115 V and 230 V single-phase operation at 60 Hz, reducing inventory needs for dual-voltage equipment. With a direct-on-line starting profile and a dual-current rating of 4.8 A at 115 V or 2.4 A at 230 V, wiring and protective devices can be selected to match the supply, simplifying panel design and commissioning.
The motor is foot-mounted with a horizontal orientation and a TENV (Totally Enclosed Non-Ventilated) enclosure, suitable for shop floors where dust and heat are common. Its steel frame and 40 °C ambient rating support reliable operation in grinders, buffers, and belt-sander setups, with straightforward alignment and mounting on standard bases.
Yes. It is designed for grinders, buffers, lathes, and belt sanders, with a rated speed of 3600 r/min (2-pole). This speed provides consistent surface finish and processing throughput for small tooling and finishing operations commonly found in workshop automation lines.
The motor carries UL/CSA safety ratings and UR certification, along with a class B insulation system. These certifications support regulatory compliance for industrial equipment, reduce risk during audits, and ensure safe operation in standard manufacturing settings.
Warranty terms indicate returned products must be handled per policy, and lead times are effectively zero with stock available at multiple warehouses (e.g., US and China). This translates to quicker replacements, reduced downtime, and improved procurement resilience for critical spares in line maintenance.
