FAQs
Plan for a footprint that matches a 145TC frame with foot-mounted, C-face mounting. Ensure 230/460 V 60 Hz power is available and that the OPSB enclosure is appropriate for the environment. Direct-on-line starting is supported, and coupling to standard drives should be verified for proper alignment and balanced loading.
This is a 2 HP, 3-phase motor rated for 60 Hz operation with dual voltage 230/460 V. It features a 4-pole design with a nominal synchronous speed of 1800 r/min, a real-world operating speed around 1760 r/min, and a service factor of 1.15. Efficiency is rated at approximately 86.5% with a shaft grounding arrangement.
Yes. It carries certifications including CSA, CSA EEV, and UR, supporting regulatory compliance across North American and international markets. The OPSB enclosure and NEMA-based design further enhance suitability for regulated manufacturing environments and energy-efficient operation.
Lead time is listed as 0 day, with stock available at multiple warehouses (US, China, GB). This enables rapid replacement, reducing downtime and accelerating maintenance schedules for critical equipment.
Expect standard bearing maintenance for 6205 Ball bearings on the drive end and 6203 Ball NDE bearings. Shaft grounding reduces bearing wear, potentially extending service life. Regular checks on enclosure integrity, lubrication schedules for the bearings, and inspection of mounting hardware will support long-term reliability.
