ABB 7BA44-9252-3335 Shaft Ground Motors - 150HP, 1785RPM
Part Number: 7BA44-9252-3335
Quick Summary
ABB Shaft Ground Motors drive high-power loads in heavy industry, such as conveyors and presses, with robust reliability. These units help prevent shaft-ground issues and bearing wear that lead to costly downtime. Where applicable, CE and UL certifications, plus enclosure IP ratings, support global deployment; SIL-rated variants are available on select configurations. With immediate US and international stock, procurement is simplified, reducing wait times and project delays. Integrating seamlessly with ABB drives and controls, these motors contribute to uptime, predictable maintenance, and a lower total cost of ownership for critical manufacturing lines. This combination delivers fast ROI on large-capital projects where downtime is unacceptable.

FAQs
Check that the motor conforms to a 150HP, 1785RPM, 3PH, 60Hz specification and uses a 445TC enclosure, which aligns with many ABB drive families. Confirm shaft-grounding configuration and ensure the control scheme supports the motor’s grounding path. Review stocking location and lead time to minimize project risk and avoid downtime during retrofit.
Shaft grounding provides a defined path for electrical currents, reducing bearing currents and voltage spikes that can degrade insulation and shorten bearing life. In high-start-stop or high-duty cycles, shaft-ground motors deliver longer service intervals, lower maintenance costs, and more stable torque delivery, which translates to higher overall equipment effectiveness (OEE).
Yes. The 150HP, 1785RPM, 445TC frame is designed for substantial torque while maintaining smooth acceleration and deceleration. When paired with appropriate ABB controls, the motor provides reliable start/stop performance, consistent speed regulation, and robust mechanical coupling to drive systems, making it suitable for high-inertia applications such as conveyors and presses.
Standard ABB powertrains commonly offer CE and UL compliance, with enclosure IP ratings tailored to the installation. Availability of SIL-rated variants depends on the configuration. For procurement, confirm the target region’s compliance requirements and request documentation for the specific stock line to ensure regulatory alignment.
Warranty requires the product to be returned for claims processing, with traceable serial records and purchase documentation. ROI drivers include reduced downtime, longer bearing life, and easier maintenance through compatible ABB drives, which lowers total cost of ownership over the motor’s life in demanding manufacturing environments.
