FAQs
Yes. The motor supports 208 V, 230 V, and 460 V inputs and is rated for both 50 Hz and 60 Hz operation. This dual-voltage, dual-frequency capability enables a single unit to serve multiple lines and regions, reducing spare parts and wiring complexity while delivering consistent torque for grinding and finishing applications.
The 7B1021WD is ideal for Grinders, Buffers, Lathes, and Belt Sanders. Its 1.5 HP output, 4-pole design, and direct-on-line starting support steady torque during continuous-duty cycles, improving surface finish quality and line uptime in metalworking and fabrication environments.
The motor is CSA-certified and UL/CSA-listed, reflecting compliance with safety and performance standards. This simplifies supplier qualification, reduces audit concerns, and supports purchasing decisions in regulated industries such as automotive and general manufacturing.
Install as a foot-mounted, horizontal motor with direct-on-line starting. Ensure alignment with standard grinder, buffer, or lathe mounting patterns, consider the 0–60 Hz voltage range, and verify shaft diameter (0.88 in) for compatible couplings. The enclosure design reduces servicing needs in dusty shop floors, improving maintenance efficiency.
With a steel frame, B-class insulation, and a 40 °C ambient rating, the motor is built for durability in challenging environments. The CSA/UL listing supports lower compliance risk, while the durable TENV design reduces maintenance intervals and extends service life, delivering a favorable total cost of ownership for grinders and finishing lines.
