CHANCS TYC-40 AC 12V CW/CCW Motor
This synchronous motor operates at 12V AC with forward and reverse capability and a compact 40 mm housing. It features a 4.5 mm shaft and a 35 mm length, suitable for fiber optic color wheels and decorative lights. The unit uses a metal/plastic gear reduction for quiet operation and continuous performance. Typical applications include Christmas trees, decorative lights, crafts, and school projects. Rated torque is modest, emphasizing smooth rotation at low power consumption.
2Pcs TYc-40 12V 50/60Hz Synchronous Motor
Two identical TYc-40 synchronous motors designed for 12V AC operation with a 4.5 mm shaft and 33 mm length. The motors run at 50/60 Hz and provide CW/CCW rotation. They’re positioned for LED decorations, ornaments, and classroom projects that require reliable, low-noise motion. Shaft diameter and mounting hole sizes align with common hobby hardware, enabling easy integration into existing displays or crafts.
CHANCS TY C-40 Synchronous Motor TYZ-42
This TYZ-42 model is a 12V AC synchronous motor with a 5 RPM operational speed and a 4.5 mm shaft. The compact form, 33 mm shaft length, and 50/60 Hz compatibility make it well-suited for precision decorative motion and small rotating displays. It shares the same robust gear approach as other TY C-series motors, delivering steady, quiet performance for extended use in props, lamps, or educational kits.
Tujoe 4 Pcs Tyc-40 Synchronous Motors
This bundle provides four TY C-40 synchronous motors designed for 12V AC operation. Each unit features a 35 mm shaft length and a 4.5 mm shaft diameter for easy mounting in compact prop projects, decorations, and crafts. The motors offer low noise and continuous rotation, making them ideal for Halloween props, Christmas displays, and small-scale motion installations where reliable reverse/forward action is desired.
Buying Guide
Key considerations when selecting a 12V AC motor for decorative or fiber optic applications include speed, torque, and shaft dimensions. For prop-based motion, 5 RPM motors provide smooth, visible movement, while 2.5–3 RPM units deliver slower, subtle rotations suitable for delicate displays. Shaft diameter is critical for mounting compatibility; most of the listed TY C-series have 4.5 mm shafts with M3 inner threads and mounting holes around 3.4 mm diameter, which aligns with common hobby hardware. Torque ratings vary; plan for enough torque to rotate your load without stalling, especially if a gear reduction is used.
Power consumption is another important factor. The 1–2 W range at 50/60 Hz is common for compact decorative motors, contributing to longer battery life for portable setups or lower thermal output in enclosed props. Noise level matters for indoor displays or silent theater props; metal/plastic gear reductions help maintain quiet operation during continuous use. In CW/CCW models, a reliable direction control can eliminate stalling issues in reversible displays.
Practical guidance for integration includes checking mounting hole spacing, confirming shaft length, and ensuring the motor can be securely fixed within your enclosure. Where you need precise, slow rotation, a motor with constant torque at low speeds helps avoid fluctuations in motion. For larger displays or heavier ornaments, higher torque variants like the TY C-50 line may be more suitable, though they may require careful power budgeting.
Finally, verify compatibility with your power source and control system. While these motors run on 12V AC, some projects benefit from dedicated controllers or relays to manage speed, direction, and pause functions. When possible, select motors with clear specifications and test samples to confirm quiet operation and consistent rotation in your specific setup.
