YBX4 Series 4-Pole Motor

The YBX4 Series 4-pole three-phase induction motor is a versatile, high-efficiency solution designed for industrial applications requiring balanced performance at moderate speeds. With a 4-pole configuration, it delivers a synchronous speed of 1,500 r/min (at 50 Hz) or 1,800 r/min (at 60 Hz), making it well-suited for machinery such as conveyors, mixers, general-purpose pumps, and HVAC systems that operate optimally at medium rotational speeds.

Constructed with a durable cast-iron frame, the YBX4 Series ensures long-term reliability in harsh environments, while its IP55 protection rating provides effective defense against dust and moisture ingress. The motor incorporates F-class insulation (rated for 155°C), enhancing thermal resilience and extending operational lifespan under continuous or variable-load conditions. Its advanced electromagnetic design minimizes energy losses, achieving IE3/IE4 efficiency levels in compliance with IEC 60034-30-1 standards, reducing energy consumption and lowering operating costs.

Key features include high starting torque, low vibration, and quiet operation, ensuring stable performance across a wide range of loads. The motor supports a power range of 0.75 kW to 315 kW and voltage compatibility from 380V to 660V, catering to diverse industrial needs. Optional accessories like thermal overload protectors and space heaters enhance safety and reliability.

With its compact design, ease of maintenance, and global certifications (IEC, NEMA), the YBX4 Series 4-pole motor is widely adopted in manufacturing, mining, and water treatment sectors, offering a cost-effective blend of efficiency, durability, and adaptability for medium-speed applications.

The YBX4 series 4-pole motor (synchronous speed 1500 r/min) is a versatile explosion-proof drive component engineered for balanced speed and torque, seamlessly integrating with reducer systems to meet diverse industrial transmission needs. Complying with IE4 ultra-high energy efficiency standards, it adopts a precision electromagnetic structure and durable mechanical design, striking an optimal balance between operational stability, load capacity, and energy conservation.

A standout advantage is its excellent adaptability to variable working conditions. The 4-pole configuration delivers steady intermediate-speed operation with strong load-bearing capacity, reducing mechanical wear on reducer components during frequent start-stop cycles and improving the overall reliability of the transmission system. Its Ex db ⅡC T4 Gb explosion-proof rating ensures safe application in hazardous environments with flammable gases, dust, or vapors, such as chemical plants, food processing facilities, and material handling workshops.

Equipped with F-class insulation and IP55 protection, the motor resists moisture, dust, and temperature variations, maintaining consistent performance in harsh or humid working environments. The optimized IC411 cooling system enhances heat dissipation efficiency, enabling continuous S1 duty operation without overheating, while the standardized mounting interface simplifies quick integration with various reducer models.

Featuring low noise emission, minimal vibration, and reduced maintenance demands, it lowers long-term operational costs. Optional intelligent monitoring functions, including temperature and load detection, further enhance operational safety. This combination of balanced performance, explosion-proof reliability, and energy efficiency makes it an ideal choice for reducer-motor assemblies in general machinery, pumps, fans, and conveyor systems.
