FAQs
Install by aligning the motor shaft with the driven equipment, securing the feet to a rigid foundation, and using a compliant belt or coupling as required. Tighten mounting bolts to manufacturer torque specs, verify level alignment, and ensure electrical connections follow local codes. With direct-on-line starting and a 3-phase supply, verify terminal block wiring for 230 or 460 V as appropriate and confirm protective devices are sized for 1.5 HP operation.
Confirm the voltage rating of 230/460 V and three-phase supply at 60 Hz. Check the service factor of 1.15, rotor speeds around 3500 r/min, and the IE3 efficiency class. Ensure the enclosure is TEFC for your environment, and verify the shaft diameter around 0.63 inches for compatible couplings. Also confirm the mount type and frame size (56C) align with your drive system.
Yes, the TEFC enclosure and 56C frame are designed for continuous duty in typical plant conditions. The motor supports continuous operation with an insulation class F and service factor of 1.15, providing robustness under elevated ambient temperatures up to 40 °C and altitudes up to 1000 m. For especially harsh environments, ensure appropriate ambient cooling and protective measures.
The motor carries CSA, CSA EEV, and UR certifications, reflecting compliance with recognized electrical safety standards. It is RoHS compliant, supporting material restrictions in many regions. These certifications help with regulatory approvals, supplier qualification, and warranty considerations in regulated industries.
The 1.15 service factor and regreasable bearings reduce unexpected downtime and maintenance costs, improving uptime and extending bearing life. IE3 efficiency lowers energy consumption, contributing to ongoing utility savings. Plan routine inspections of lubrication intervals, inspect belt/pulley alignment during scheduled maintenance, and maintain clean cooling paths to preserve performance over the motor’s life.
