Honeywell International Inc. SR3728-3734-7-56C Brushed DC Motor

The Honeywell SR3728-3734-7-56C brushed DC motor operates on 90 VDC, uses a 56C frame, and runs at 1,750 RPM. As a brushed DC design, it relies on a carbon-brush and commutator arrangement to provide straightforward speed control and reliable startup in compact installations. The SR3728-3734-7-56C model identifier designates this specific Honeywell unit for applications requiring a 56C-frame motor powered by a 90-volt DC supply, aligning with standard mounting footprints and drive interfaces associated with that frame size. With a nominal speed of 1,750 RPM, it suits drive systems and small machinery that operate at moderate speeds without gearing. Maintenance for brushed DC motors typically includes periodic inspection of brushes and the commutator to ensure consistent performance. The model number aids replacement, ordering, and cross-reference within Honeywell's catalog and compatible aftermarket inventories.
