FAQs
This motor uses a foot-mounted, horizontal mounting arrangement with a 56C frame and a 0.63 in shaft diameter. Plan for a secure base, proper shaft alignment, and compatible mounting hardware. TEFC protection supports routine washdowns and dusty environments, while the sealed 6203 bearing reduces maintenance needs. Ensure the drive wiring matches the 90 V armature and 100 V/50 V field voltage requirements.
The motor delivers 0.33 HP at 1750 r/min with a 1.00 service factor, providing reliable startup and steady speed for light conveyors and small processing lines. Its 56C frame and TEFC enclosure simplify integration with existing equipment, while the inbuilt mounting options support quick retrofits. Expect consistent performance under standard factory temperatures up to 40 °C.
Yes. The unit carries CSA and UR certifications and aligns with NEMA standards, ensuring regulatory compliance in many industrial settings. TEFC enclosure adds protection in environments with dust and moisture. This combination supports safer operation, easier supplier qualification, and smoother audits for regulated facilities.
The product notes a standard warranty framework with a requirement that warranty returns be processed if needed. Lubrication is listed as Regreasable, and bearings are sealed (6203), which reduces maintenance intervals. Scheduling regular inspections and following ABB’s field maintenance guidelines helps extend life and maintain peak efficiency.
Stocked At Warehouses includes locations like US and China with 0-day lead times, enabling rapid fulfillment and flexible logistics. Its 56C frame, TEFC enclosure, and 0.33 HP rating make it a viable drop-in for multiple applications, while field and armature voltages accommodate common DC drive controls, reducing lead times for procurement and installation.
