Altra Industrial Motion Corp. V92500-B Industrial Motor

The V92500-B is a Boston Gear DC motor offered by Altra Industrial Motion, identified in the V-series as a 1/4 horsepower unit designed for low-to-moderate load applications. It uses a 90 V armature and a field winding rated for 50/100 V, allowing control of armature and field voltage to shape speed and torque in DC drive systems. The motor features a B5 shaft bore and a NEMA 56C mounting footprint, enabling compatibility with common gearboxes, couplings, and mounting plates without custom adapters. As part of Altra’s broad power-transmission portfolio, the V92500-B benefits from established manufacturing practices and standard interfaces typical of 56C/NEMA-size motors. The model designation V92500-B distinguishes this specific configuration within Boston Gear’s catalog and the wider Altra family, supporting straightforward replacement in equipment designed for conventional DC motors with 56C mounting and a B5 bore. This combination of electrical ratings and mechanical interfaces makes it suitable for integrated drive systems where stable DC performance and easy interchangeability are important.
