The **18VP-263S-R** is a specific part number typically associated with a **micro-motor** or a **geared motor assembly**, often used in small consumer electronics like optical disc drives (CD/DVD), office equipment, or small robotics. Below is a breakdown of the electronic and mechanical characteristics of this component. --- ### 1. Technical Specifications The following table outlines the general technical parameters typical for this class of motor: | Feature | Specification | | :--- | :--- | | **Input Voltage** | Typically 3V to 6V DC | | **Motor Type** | Brushed DC Micro Motor | | **Output Type** | Geared Shaft (often with a worm gear or pulley) | | **Material** | Metal housing with plastic internal gears (if applicable) | | **Compliance** | RoHS Compliant (indicated by the "-R" suffix) | --- ### 2. Key Components & Construction The "18VP" series generally follows a standard internal structure for small DC motors: * **Rotor (Armature):** The internal rotating part consisting of copper wire coils. * **Stator:** Permanent magnets located inside the motor housing that provide the magnetic field. * **Brushes:** Precious metal or graphite brushes that transfer electrical current to the rotating commutator. * **Commutator:** A segmented cylinder that reverses current flow to maintain continuous rotation. * **Shaft:** The output component, which in the "263S" variant, often features a specific length and diameter suited for press-fit gears. --- ### 3. Applications These parts are engineered for high-precision, low-torque movements. Common use cases include: 1. **Optical Drives:** Moving the laser pickup head or ejecting the disc tray. 2. **Printers:** Paper feeding mechanisms or moving the print head carriage. 3. **Smart Locks:** Actuating the deadbolt or locking pin in electronic door locks. 4. **Consumer Gadgets:** Small rotating displays or motorized toys. --- ### 4. Part Number Decoding (General) While naming conventions vary by manufacturer (such as Mabuchi or Nidec), the code usually breaks down as follows: * **18V:** Relates to the motor frame size or specific series diameter. * **P:** Often denotes the magnet type or a specific performance tier. * **263S:** The specific winding configuration (determines RPM and Torque). * **-R:** Standard industry notation for **RoHS Compliance** (Restriction of Hazardous Substances).
