Motive DELPHI - Three Phase Motors Size 160-355

Motive's DELPHI three-phase motors, encompassing sizes 160 to 355, are designed to meet rigorous industrial standards with their cast iron frames and multiple advanced features. The motors adhere to standardized dimensions per IEC 72-1 and support multiple voltage and frequency operations (50/60Hz). They come with F class insulation, with optional H or H+ (delfire) upon request, ensuring high thermal endurance. The motors are rated for S1 continuous duty service and boast IP55 protection, with higher protection levels like IP56, 66, and 67 available on request. The tropicalized winding and reinforced insulation make these motors suitable for harsh environments and inverter power supplies, specifically recommending insulated bearings for motors from 110kW upwards to avoid electrical erosion. Efficiency is categorized under IE2, IE3, and IE4 standards per IEC 60034-30-1. The junction box, adhering to IP65, is made of aluminum for sizes up to 280 and is adjustable in 90° steps. Self-lubricating ZZ bearings reduce maintenance need in sizes 160 to 280, while sizes from 315 upwards have grease nipples and roller bearings to handle high radial loads. The motors incorporate three standard PTC thermistors for protection and feature lifting eye bolts for ease of handling. The terminal box can also be mounted laterally upon request. Additionally, the company offers detailed manuals, certificates, and catalogs for download, highlighting compliance and specifications.
