The **M2SBS-412-R/N** is a specific model of an **Electromagnetic Brake** (often referred to as a micro-brake or spring-actuated brake). These components are critical in motion control for holding a load in place when power is removed. Below is a breakdown of its electronic and mechanical specifications. --- ### 1. General Specifications The "M2SBS" series typically refers to a line of non-excitation actuated brakes. This means the brake is **engaged** (locked) by default and **disengaged** (released) when electrical power is applied. | Feature | Description | | :--- | :--- | | **Type** | Non-excitation (Power-off) Electromagnetic Brake | | **Bore Size** | Approximately 12mm (indicated by the "12" in the suffix) | | **Voltage** | Typically 24V DC (Standard for industrial control) | | **Application** | Stepper motors, Servo motors, Medical equipment, Robotics | --- ### 2. Key Electronic Components & Principles The internal "electronic" operation relies on electromagnetic induction and resistance: * **Solenoid Coil:** The heart of the unit. When a DC current flows through this copper coil, it generates a magnetic field. * **Armature Plate:** A ferrous metal plate that is pulled toward the coil by the magnetic force, compressing internal springs to release the friction disc. * **Power Consumption:** These units are designed for low wattage to prevent overheating during continuous "release" states. * **Lead Wires:** Usually color-coded (Red/Black or similar) for 24V DC input. Polarities are often interchangeable unless a diode is integrated. --- ### 3. Operational Logic The M2SBS-412-R/N operates on a "Fail-Safe" logic: 1. **Power OFF (0V):** Internal springs push the armature against the friction hub. The shaft is locked. This prevents the load from falling during a power outage. 2. **Power ON (24V DC):** The electromagnetic coil creates a field stronger than the spring tension. The armature is pulled away, allowing the friction hub (and the motor shaft) to rotate freely. --- ### 4. Technical Summary Table | Parameter | Typical Value (M2SBS Series) | | :--- | :--- | | **Static Friction Torque** | ~0.4 Nm to 1.2 Nm (depending on exact sub-spec) | | **Rated Voltage** | DC 24V | | **Power Rating** | 5W - 8W | | **Response Time** | < 30ms (Engagement) / < 50ms (Release) | | **Insulation Class** | Class E or B (120°C - 130°C) | --- ### 5. Installation Note When integrating the **M2SBS-412-R/N**, ensure that the DC power supply is regulated. Voltage spikes or "noisy" power can cause the brake to chatter or fail to release fully, leading to premature wear of the friction linings.
