Industrial PM925T Three-Phase AC Induction Motor

Boston Gear PM925T is a compact permanent-magnet DC motor in a 56C frame that delivers 1/4 horsepower at about 1,750 rpm from a 90 VDC supply, with a full-load current of roughly 2.5 A, and it uses a totally enclosed, non-ventilated design to protect the windings in dusty or damp environments. This PM925T family is manufactured by Boston Gear, part of ALTRA Industrial Motion, and is cataloged with PM925T and PM925AT-B (item codes 19121 and 59478), offering a footprint that is compatible with 56C mounting patterns. A washdown variant, PM925T-WD, is available at 90 VDC with similar speed (about 1,750 rpm) and a current draw around 2.7 A, expanding suitability for environments where extra protection against moisture is desired. Boston Gear PM925T is part of a broader family of permanent-magnet, totally enclosed DC motors that share a 56C mounting footprint, enabling straightforward replacement in compatible drive assemblies.
