The **M8R25TAJ-R** is a specific part number typically associated with a **Geared Induction Motor**, often manufactured by companies like **GGM** or similar industrial automation brands. These motors are widely used in conveyor systems, packing machines, and medical equipment. --- ### 1. Technical Specifications The part number can be broken down into specific electrical and mechanical characteristics: | Feature | Description | | :--- | :--- | | **Motor Type** | AC Induction Motor (Reversible) | | **Frame Size** | 80mm x 80mm (indicated by "8") | | **Output Power** | 25 Watts | | **Voltage** | Single Phase (Standard 220V-240V AC) | | **Shaft Type** | Pinion Shaft (for Gearhead attachment) | | **Terminal Type** | Terminal Box (indicated by "T") | --- ### 2. Key Electronic Components To operate this motor, several electronic parts and accessories are required: #### A. Running Capacitor Since this is a single-phase induction motor, it requires a **Phase-shift Capacitor** to start and maintain rotation. - **Purpose:** Creates a phase difference between the primary and secondary windings. - **Typical Value:** Usually between **1.5μF to 2.5μF / 450V** (Check the motor nameplate for the exact value). #### B. The Brake/Clutch Mechanism (If "R" suffix implies Reversible) - **Reversible Motor Logic:** These motors have a built-in simple friction brake to prevent over-run when power is cut. - **Direction Control:** Requires a **DPDT (Double Pole Double Throw)** switch or a set of relays to swap the connection of the capacitor between the windings. #### C. Gearhead (Mechanical Coupling) The "M8R25TAJ" refers to the motor unit. It is designed to be bolted to a **Gearhead** (e.g., 8GBK series) to reduce speed and increase torque. --- ### 3.
