SP500508-1

Overview

The DB Unlimited SP500508-1 is a miniature DC gear motor designed for compact applications. It features a brass gear train and operates on a 3V DC supply. The unit delivers a stall torque of 2.4 oz-in (1.75 kg-cm) and a no-load speed of 160 RPM. Key electrical parameters include a no-load current of 90 mA and a stall current of 1.5 A. The motor shaft has a diameter of 1.5 mm, and the overall dimensions are approximately 50mm in length, 50mm in width, and 8mm in height.

Feature Summary

• Compact form factor suitable for space-constrained designs
• Brass gear construction for durability and smooth operation
• Low voltage direct current operation

Applications

• Automated blinds and shades
• Small robotic mechanisms
• Consumer electronic actuators

Procurement Notes

Verify the specific shaft configuration and mounting hole pattern against your mechanical design requirements before ordering. Confirm that the 3V operating voltage aligns with your power supply system. Ensure the stall torque rating meets the peak load demands of your application to prevent motor burnout under jam conditions.

Selection Notes

Select this model when a low-voltage, high-torque solution is required in a minimal footprint. Consider the 1.5mm shaft diameter for coupling compatibility. Evaluate if the 160 RPM no-load speed is sufficient for your cycle time requirements. Brass gears offer better wear resistance than plastic alternatives in continuous duty scenarios.

Part Context

DB Unlimited specializes in custom and standard miniature DC motors. The SP series represents their line of small gear motors. This specific part number denotes a standard configuration within their catalog. The brand focuses on providing ready-to-use actuation components for OEMs.

Replacement Considerations

Direct replacements must match the 3V DC input, similar physical envelope, and comparable torque-speed characteristics. Verify shaft diameter and keyway details if present. Cross-reference with other manufacturers offering 50mm x 50mm x 8mm gear motors.
