YBX4 Series 2-Pole Motor

The YBX4 Series 2-pole three-phase induction motor is a high-speed, energy-efficient solution engineered for industrial applications demanding rapid rotational performance. With a 2-pole configuration, it achieves a synchronous speed of 3,000 r/min (at 50 Hz) or 3,600 r/min (at 60 Hz), making it ideal for machinery such as centrifugal fans, high-speed pumps, compressors, and machine tool spindles that require precise and consistent high-speed operation.

Constructed with a robust cast-iron frame, the YBX4 Series ensures durability in demanding environments, while its IP55 protection rating provides reliable defense against dust and water ingress. The motor features F-class insulation (rated for 155°C), enhancing thermal stability and extending service life under continuous or heavy-duty operation. Its optimized electromagnetic design reduces energy losses, meeting IE3/IE4 efficiency standards per IEC 60034-30-1, which lowers operational costs and supports sustainability goals.

Key advantages include high starting torque, low vibration, and quiet operation, ensuring smooth performance even under varying loads. The motor supports a power range of 0.75 kW to 315 kW and voltage compatibility from 380V to 660V, accommodating diverse industrial requirements. Optional accessories like thermal overload protectors and vibration dampers enhance safety and reliability.

With its compact design, ease of maintenance, and global certifications (IEC, NEMA), the YBX4 Series 2-pole motor is widely adopted in manufacturing, HVAC, and automotive sectors, offering a cost-effective balance of speed, efficiency, and durability for high-performance applications.

The YBX4 series 2-pole motor (synchronous speed 3000 r/min) is a high-speed, energy-efficient explosion-proof drive component designed for seamless integration with reducer systems, catering to high-speed industrial transmission demands. Adhering to IE4 ultra-high energy efficiency standards, it features a compact electromagnetic design and high-strength mechanical structure, balancing rapid rotational speed with stable power output for precision equipment.

A core advantage lies in its exceptional high-speed performance and energy-saving capability. The 2-pole configuration achieves fast rotational speeds with minimal energy loss, reducing the load on reducers during speed adjustment and improving overall transmission efficiency. Its Ex db ⅡC T4 Gb explosion-proof rating ensures safe operation in hazardous environments with flammable gases or dust, such as petrochemical plants, precision processing workshops, and power equipment.

Equipped with F-class insulation and IP55 protection, the motor resists moisture, dust, and high-temperature effects, maintaining reliable performance under continuous high-speed operation. The optimized IC411 cooling system enhances heat dissipation, preventing overheating even during long-term S1 duty cycles, while the standardized mounting interface simplifies compatibility with various reducer models.

Featuring low vibration, low noise, and durable construction, it minimizes maintenance costs and extends service life. Optional speed monitoring and overload protection functions further enhance operational safety. This combination of high-speed efficiency, explosion-proof reliability, and energy conservation makes it an ideal choice for reducer-motor assemblies in precision machinery, ventilation equipment, and high-speed transmission systems.
