YEJ2 Series Electromagnetic Braking Three Phase Motor Working Principle:

• Basic Motor Operation
  The YEJ2 series is a type of three-phase induction motor that operates similarly to a standard three-phase motor. When a three-phase AC supply is provided to the stator windings, a rotating magnetic field is produced. This rotating field induces a current in the rotor, which then generates a magnetic field. The interaction between the stator’s rotating magnetic field and the rotor’s induced field produces the torque that causes the rotor to turn, powering mechanical loads.
• Electromagnetic Braking Mechanism
  The key feature of the YEJ2 series motor is the integrated electromagnetic brake. The motor is equipped with an additional electromagnetic brake assembly attached to the motor shaft. This brake operates through the use of a magnetic field generated by a DC current, which is applied to a brake coil or electromagnet. The braking mechanism is activated when DC voltage is applied, causing the brake to engage and apply a force on the rotor, halting its motion.
• Brake Engagement and Disengagement
  When the motor is powered, the electromagnetic brake is disengaged, allowing the motor to run normally. However, when the power supply is cut or a braking signal is sent, the DC current is applied to the brake coil. This creates a magnetic field that attracts a brake pad or armature, causing the rotor to slow down and come to a stop. The brake typically engages when the motor is de-energized or when a stop command is given, making it useful in applications that require rapid stopping or precise control of the motor’s deceleration.
• Braking Action
  The electromagnetic brake provides a quick, controlled stop by generating a braking force through electromagnetic attraction. This braking action is achieved without the use of mechanical friction parts like traditional brakes, which makes it more efficient, less prone to wear, and capable of providing a more reliable and maintenance-free solution for motor stopping. The brake is released when the DC current is turned off, and the motor can resume operation.
• Applications
  The YEJ2 series electromagnetic braking motors are widely used in applications requiring rapid stopping and precise control, such as cranes, hoists, elevators, conveyors, and other industrial machinery where stopping the motor quickly or holding it in place is crucial. The built-in electromagnetic brake allows for a compact design, reducing the need for additional external braking systems while providing high safety and efficiency.

YEJ2 Series Electromagnetic Braking Three Phase Asynchronous Motor Applications:

1. Cranes and Hoists
   The YEJ2 series motor is extensively used in crane and hoist systems, where precise control over the motor’s start and stop functions is critical. The integrated electromagnetic braking system allows for rapid stopping of the load, ensuring safe and efficient operation in lifting and lowering applications. This is particularly useful in environments like warehouses, ports, and construction sites where precise load positioning is required.
2. Elevators and Escalators
   Elevators and escalators rely on the YEJ2 series motor for smooth, quick stops and controlled starts. The electromagnetic brake ensures that the motor halts instantly when the elevator reaches the desired floor or when the escalator must stop, providing safety and preventing overshooting. The system’s ability to hold the load in a stationary position is also essential in elevator applications, enhancing safety and user comfort.
3. Conveyors and Material Handling Systems
   In automated material handling and conveyor systems, the YEJ2 series motor offers reliable braking capabilities. It ensures that conveyors stop quickly and safely when required, preventing damage to goods or equipment. The motor’s electromagnetic brake helps maintain system efficiency by providing rapid and precise stopping without the wear and tear associated with mechanical brakes, making it ideal for high-duty cycles in production lines, warehouses, and sorting facilities.
4. Machine Tools and CNC Equipment
   Machine tools, such as CNC machines, benefit from the YEJ2 series motor’s braking function, which helps in fast stopping of the spindle or cutting tools after a job is completed. The ability to quickly and accurately decelerate prevents damage to the machine and enhances productivity. Electromagnetic braking in these systems ensures the tool can be stopped instantly, improving precision and safety in operations like milling, turning, and grinding.
5. Winders and Reels
   The YEJ2 motor is also suitable for applications like winders and reels, commonly used in industries such as textiles, wire drawing, and cable production. The motor’s electromagnetic brake ensures that the reels stop with high precision, preventing overrun or damage to the material being wound. This capability is crucial in industries where controlled winding or unwinding of material is essential for quality and efficiency.

These applications demonstrate the versatility and reliability of the YEJ2 series electromagnetic braking three-phase asynchronous motor, particularly where precise control, rapid stopping, and safety are paramount.
