The **MAH22FBA-R** is a specific technical component part number, most commonly associated with **Magtrol’s Hysteresis Brake** series or specific industrial motor/clutch components. Based on industrial electronic standards, here is the breakdown of its electronic and mechanical properties. --- ### 1. Component Overview The MAH22FBA-R belongs to the category of **Electromagnetic Hysteresis Brakes**. These parts are used for precise torque control, tensioning, and load simulation. | Feature | Specification | | :--- | :--- | | **Part Type** | Hysteresis Brake / Clutch | | **Operating Principle** | Electromagnetic Induction | | **Torque Control** | Proportional to Current | | **Cooling Method** | Convection (Standard) | | **Mounting** | Flange Mount | --- ### 2. Electronic Operating Characteristics The electronic performance of the MAH22FBA-R is defined by how the internal coil interacts with the magnetic rotor. * **Current-to-Torque Linearity:** Unlike friction-based brakes, the torque produced is strictly proportional to the DC current applied to the coil. This allows for extremely precise electronic control via a PLC or dedicated controller. * **Voltage Requirements:** Typically operates on a **24V DC** or **90V DC** system (depending on the specific winding variant), requiring a constant current power supply for optimal stability. * **Residual Torque:** Designed with high-grade magnetic materials to ensure near-zero torque when the electronic signal is removed (de-energized). * **Response Time:** The electronic response is nearly instantaneous, limited only by the inductive properties of the internal coil. --- ### 3. Key Technical Specifications | Parameter | Value (Typical for MAH22 series) | | :--- | :--- | | **Max Torque** | ~0.7 to 1.2 Nm (depending on frame) | | **Max Speed** | 10,000 - 15,000 RPM | | **Coil Resistance** | Specific to voltage rating (e.g., 100-500 Ω) | | **Power Dissipation** | Determined by surface area and airflow | --- ### 4. Typical Electronic Circuit Integration To control the MAH22FBA-R, the following electronic setup is usually required: 1. **Power Supply:** A regulated DC source. 2. **Current Controller:** A Pulse Width Modulation (PWM) or Linear Current driver. 3. **Feedback Loop:** Often paired with an encoder or load cell to provide closed-loop tension control. --- ### 5. Application Areas * **Wire & Cable Tensioning:** Maintaining constant tension during spooling. * **Testing Rigs:** Simulating loads for small electric motors. * **Packaging Machinery:** Controlling the unwind force of films and labels. * **Medical Equipment:** Precise resistance control in rehabilitation devices.
