Overview:

YE3 series (frame size H355--450) low-voltage, high-power, and high-efficiency three-phase asynchronous motors are our company's latest electromagnetic calculation and analysis software, combined with domestic and foreign advanced motor design and manufacturing technologies, and manufactured with new technology and new materials. The high-efficiency, high-power-density industrial prime mover. This series of motors has the characteristics of compact structure, high efficiency, small size, light weight, low vibration and high reliability. It can be widely used in petroleum, chemical, coal mining, metallurgy, pharmaceutical, building materials, food, machining and other industries to drive various general machinery such as blowers, compressors, water pumps, ball mills, crushers, mixers, belt conveyors, Conveyors, various mechanical processing equipment, etc.

The performance of this series of motors conforms to the provisions of IEC72 and GB755. The energy efficiency level conforms to IEC60034--30IE3 level.

The cooling method of this series of motors adopts IC411 or IC416.

The installation methods of this series of motors can be made into IMB3, IMB35, IMV1, IMV5 and so on.

The rated voltage of this series of motors can be made into 380V, 660V, 1140V. The rated frequency can be made 50Hz and 60Hz, and can also be made with a frequency of 50-60Hz.

(W), wet tropical zone (TH), outdoor wet tropical zone (WTH), anti-corrosion type (F1, F2), outdoor anti-corrosion type (WF1, WF2), etc.

 

Structural features:

This series of motors adopts high-strength cast iron frame, vertical and horizontal heat dissipation rib structure, resin sand molding process, beautiful appearance and high mechanical strength. The motor is made of high-quality low-loss silicon steel sheet, made of stator and rotor cores, and high-insulation performance magnet wire, which is dipped by vacuum pressure (VPI), so that the winding stator has good electrical performance and insulation performance.

The ventilation and heat dissipation structure of this series of motors is divided into an inner air path and an outer air path. The inner air path passes through the inner fan and rotor blades, and circulates the heat inside the motor to the cooling air ducts and cooling ribs on the motor base, and then passes through the outer The external fan on the air path dissipates the heat on the base shell, effectively controls the temperature rise of the motor, and improves the reliability of the motor operation.

The rotor of this series of motors adopts cast aluminum or copper strip structure. The dynamic balance accuracy of the rotor is assessed according to G1.0 level. The motor has a small vibration value and stable operation. The external fan structure of this series of motors adopts axial flow fans and backward inclined centrifugal fans, which not only ensures the effective heat dissipation of the motor, but also reduces the ventilation noise of the motor.

This series of motor parts processing and manufacturing adopts advanced technology and high-precision processing equipment, so that the processing accuracy of motor parts can reach the best size, and ensure that the matching clearance of each part of the motor parts reaches an ideal state when the motor is assembled. The motor bearing adopts well-known brands at home and abroad, and a reliable measure of blocking shaft current is adopted for the variable frequency motor to ensure that the lubricating oil film will not fail when the motor bearing is running, which improves the service life of the bearing and makes the operation of this series of motors more reliable.
