YD series pole-changing multi-speed three-phase asynchronous motor

product description

In order to solve the three major problems of traditional motors, namely large size, heavy weight and high noise, Huanian Motor has developed the YD series variable pole multi-speed three-phase asynchronous motor. This motor has many advantages such as high efficiency, energy saving, small size, light weight, low noise and low vibration, providing users with a better choice.

The appearance of this series of motors is the same as that of the Y and Y2 series motors, and the power level and installation dimensions are in line with the specifications of the International Electrotechnical Commission (IEC) and the German Industrial Standard (DIN). This ensures that the motor has good compatibility and versatility worldwide. The insulation level of the YD series motor is B, but users can also choose higher F or H insulation levels to meet different usage requirements. In addition, the protection level of this series of motors is IP44, and users can also choose higher IPS4, IPS5 or IPS6 protection levels to cope with more severe environmental conditions.

It is worth mentioning that this series of motors is also equipped with an electromagnetic brake, which derives the YDEJ electromagnetic brake variable pole multi-speed three-phase asynchronous motor. This enables the motor to brake quickly and safely when it stops running, improving the safety and reliability of operation.

The YD series variable-pole multi-speed three-phase asynchronous motor changes the number of motor poles by changing the traditional stator winding connection method, thereby achieving speed change. This design allows the motor to adjust the power and speed in stages according to the different requirements of the load to achieve a reasonable match with the load. This not only simplifies the design of the speed change system, but also significantly saves energy. This feature is particularly suitable for application scenarios that require frequent speed changes, such as in industries such as mechanical processing, transportation, and textiles, which can improve production efficiency and reduce operating costs.

Technical features

(1) High efficiency and energy saving

Energy efficiency level: YD series motors are designed to meet high energy efficiency standards, usually reaching or exceeding IE3 (International Energy Efficiency Level 3) standards to ensure high energy conversion efficiency of the motor during operation. This means that with the same power output, the motor consumes less electricity, reducing energy waste.

Energy-saving advantages: By optimizing electromagnetic design and using high-efficiency materials, YD series motors can maintain efficient operation under a variety of load conditions. Its pole-changing multi-speed feature enables the motor to adjust power and speed according to load requirements, thereby avoiding excessive energy consumption and further improving overall energy utilization efficiency.

(2) Small size and light weight

Structural design: YD series motors achieve a compact design by optimizing internal structure and material selection. The use of high-density electromagnetic steel sheets and high-performance winding materials not only reduces the size of the motor, but also significantly reduces the weight.

Compactness: The overall dimensions of the motor are the same as those of the traditional Y and Y2 series motors, but the internal design is more compact and efficient. This allows the YD series motors to occupy less space during installation, making them ideal for applications that require space saving, such as in industrial automation systems with compact equipment.

Material application: Light alloy materials are used to manufacture the casing and end covers, while ensuring the strength and durability of the motor, further reducing the overall weight.

(3) Low noise and small vibration

Noise control: YD series motors adopt low-noise bearings and optimized airflow path design during the design process to reduce noise during operation. The fan and cooling system of the motor are carefully designed to ensure effective heat dissipation and reduce aerodynamic noise during operation.

Vibration control: Through high-precision rotor dynamic balancing and precise bearing support design, the vibration of YD series motors is effectively controlled during operation. The motor remains stable during high-speed operation, reducing the impact on surrounding equipment.

Structural optimization: The close fit of internal components such as the stator and rotor, as well as the solid mechanical structure design, enable the motor to maintain low vibration characteristics under various operating conditions, extending the service life of the motor and equipment.
