MM3474F12VBE

Overview

The MM3474F12VBE is a 4-wire, 1.8-degree step angle hybrid stepper motor manufactured by Mitsumi Electric. It features a 2-phase bipolar configuration with a holding torque of 120 N.cm (169 oz.in) and a phase resistance of 1.5 Ohms per phase. The motor operates at a rated current of 2.0 Amps per phase and has an inductance of 3.0 mH per phase. It utilizes a 42mm frame size with a shaft diameter of 5mm and a shaft length of 25mm. The unit weighs approximately 280 grams and is designed for precise positioning applications requiring high torque density.

Feature Summary

• High holding torque output within a compact 42mm frame size
• Bipolar winding configuration optimized for standard driver circuits
• Precision hybrid rotor construction ensuring consistent step accuracy

Applications

• Industrial automation positioning systems
• Medical equipment actuation mechanisms
• Office automation devices such as printers and scanners

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm shaft dimensions and connector types. Ensure driver compatibility with the specified 2.0A per phase rating and 1.5 Ohm resistance. Confirm environmental operating conditions match application requirements before finalizing procurement orders.

Selection Notes

Select this model when high torque is required in a limited space. Ensure the driving circuit supports bipolar operation and can deliver the rated 2.0A current. Consider thermal management solutions if continuous operation exceeds standard duty cycles due to the relatively low phase resistance.

Part Context

This component belongs to Mitsumi's standard line of hybrid stepper motors. These units are widely used in applications demanding reliable incremental motion control. The 42mm frame series offers a balance between physical footprint and mechanical output capabilities for general purpose automation tasks.

Replacement Considerations

Direct replacements must match the 42mm frame, 1.8-degree step angle, and similar electrical parameters. Verify shaft diameter and keyway specifications to ensure mechanical compatibility. Consult manufacturer cross-reference lists for verified equivalent part numbers from other suppliers.
