The **MAH76FBD-R** is a high-performance, brushless DC (BLDC) motor from the **MAH series** manufactured by **Sanyo Denki** (San Motion). These motors are designed for high-speed, high-torque applications requiring precise control and compact integration. --- ### 1. Technical Specifications The following table outlines the primary electronic and mechanical characteristics of the MAH76FBD-R: | Parameter | Value | | :--- | :--- | | **Motor Type** | Brushless DC Motor (BLDC) | | **Output Power** | Approximately 100W - 150W (Series Dependent) | | **Rated Voltage** | 24V DC / 48V DC | | **Rated Speed** | 3000 RPM | | **Rated Torque** | 0.32 N·m (approx.) | | **Feedback Mechanism** | Hall Effect Sensors | | **Insulation Class** | Class E (120°C) | --- ### 2. Key Electronic Components & Features #### A. Internal Hall Sensors The motor utilizes three internal Hall Effect sensors positioned at 120-degree electrical intervals. These sensors detect the position of the permanent magnet rotor, allowing the electronic controller to switch the current in the stator windings (commutation) at the correct time. #### B. Permanent Magnet Rotor The "F" in the part number often indicates a specific rotor density or frame size. It uses high-energy neodymium magnets to ensure high torque-to-weight ratios and low inertia for rapid acceleration. #### C. Stator Windings The stator consists of high-quality copper windings. Because it is brushless, there are no carbon brushes to wear out, which significantly reduces electronic noise (EMI) and extends the operational lifespan. #### D. Connection Interface The motor typically features a lead-wire or connector-type interface: * **Power Leads:** U, V, W phases for the motor drive. * **Sensor Leads:** Vcc, GND, and the H1, H2, H3 signals for feedback. --- ### 3. Application Use Cases Due to its electronic efficiency and high-speed stability, the MAH76FBD-R is commonly found in: 1. **Medical Equipment:** Centrifuges and surgical pumps. 2. **Conveyor Systems:** Small-scale precision sorting. 3. **AGVs (Automated Guided Vehicles):** Wheel drives for small warehouse robots. 4. **Office Automation:** High-speed scanning or sorting machinery. --- ### 4.
