Feature: 4-pole, single-phase motor (1800 r/min) delivers steady torque for light-to-medium machine-tool loads. Business impact: Improves process stability and reduces cycle times, translating to higher throughput in grinding and buffing applications. Application: Ideal for compact footprint tool rooms and OEM equipment using 0.75 Hp drive units. Feature: TENV enclosure (Totally Enclosed Non-ventilated) with 40 °C ambient rating. Business impact: Protects windings and bearings from dust and contamination while maintaining performance in shop floors without climate control. Application: Suitable for open workshops and semi-enclosed machine installations where venting is impractical.Feature: Foot-mounted base, horizontal mounting and standard drive end flange. Business impact: Simplifies retrofits and new installations with minimal frame adaptation, reducing installation time and mounting hardware costs. Application: Common in retrofit projects for grinders, lathes, and belt sanders.Feature: Voltage rating 115 V / 230 V, direct-on-line starting. Business impact: Flexible power sourcing and straightforward electrical connection with lower startup impedance, reducing control panel complexity. Application: Fits standard US/EU supply scenarios for small-capacity machine tools.Feature: 0.75 Hp output, 4P, shaft diameter 0.75 in, rated current 4.6 A | 2.3 A. Business impact: Predictable peak loading, efficient energy use, and easier overload planning in continuous-duty operations. Application: Suitable for small-capacity drives and direct-drive tool heads in grinders and buffers.Feature: Stocked at multiple warehouses (US and China). Business impact: Accelerates fulfillment, minimizes downtime for critical spindle replacements and OEM spares.

FAQs
Yes. The 7B8100WD is a 1-phase motor designed for direct-on-line starting, featuring a 4-pole configuration and 0.75 Hp output. Ensure proper overload protection and switchgear compatible with 115/230 V supplies to maximize startup reliability.
It uses a Totally Enclosed Non-ventilated (TENV) enclosure, rated for ambient up to 40 °C. This enclosure protects internal windings from dust and debris, enabling installation in open workshops and non-climate-controlled environments without compromising motor life.
The motor carries UL/CSA certification and UR recognition, confirming compliance with common North American safety and energy standards, and ease of integration into regulated environments.
The motor is foot-mounted, horizontal, with a standard drive end flange and a 0.75 in shaft diameter. This facilitates straightforward retrofits into existing tool frames and common machine tool configurations.
Best suited for grinders, buffers, lathes, and belt sanders in continuous-duty setups. Regular maintenance should focus on bearing health and winding insulation, with attention to ambient temperature limits and proper overload protection to preserve performance over time.
