H160-31511-250KW
The outer casing is protected to prevent debris or water droplets larger than 12mm from entering the motor at an angle of 60° to the vertical line. It is suitable for various mechanical equipments with long running time and high load rate.
3. High efficiency three-phase asynchronous motor
YX (IP44)
H100-2801.5-90KW
The use of cold-rolled silicon steel sheets and new processes to reduce motor losses, the efficiency is 3% higher than the average of the Y series, suitable for heavy-duty start-up occasions, such as lifting equipment, winches, compressors, pumps, etc.
4. Winding type three-phase asynchronous motor
YR (IP44) (IP23), JRO2, JR2
H132-2804-75KW
The rotor is of a winding type, and a large starting torque can be obtained by the external resistor of the rotor and the motor speed can be adjusted step by step within a certain range.
5. Frequency conversion multi-speed three-phase asynchronous motor
YD (IP44), JDO2
H80-2800.55-90KW
Derived on the Y basic series, using multiple sets of stator winding connections to achieve motor speed shifting. Suitable for universal, combined, special cutting machine tools and transmission mechanisms requiring multi-speed.
6. High slip rate three-phase asynchronous motor
YH (IP44), JHO2
H80-2800.55-90KW
Derived in the Y basic series, with rotor deep groove and high resistivity rotor conductor structure, large stall torque, high slip rate, small stall current, soft mechanical characteristics, can withstand impact load for large torque of transmission flywheel And uneven impact loads, such as hammers, shears, punches, forging machines, etc.
7. Electromagnetic speed regulation three-phase asynchronous motor
YCT, JZT
H112-3350.55-90KW
It is a combination of Y series motor and electromagnetic clutch, which is a constant torque stepless speed regulating motor. It is used for constant speed stepless speed regulation, especially for loads such as fans and pumps.
8. Electromagnetic brake three-phase asynchronous motor
YEJ
H80-2250.55-45KW
It is made up of a DC disc brake on one end of the Y series motor, which can be quickly stopped and correctly positioned. Used in lifting machinery, transportation, packaging, construction, food, woodworking machinery, etc.
9. Increased safety three-phase asynchronous motor
YA, JAO2
H80-2800.55-75KW
In the basic series of Y, the structure and protection measures are strengthened, which is suitable for occasions with explosion hazard.
10. Flameproof three-phase asynchronous motor
YB, BJO2
H80-3150.55-220KW
Derived on the basic series of Y, produced according to the standard of explosion-proof. Used in coal mines and factories with flammable gases.
11.Outdoor three-phase asynchronous motor
Y-W, JO2-W
H80-3150.55-160KW
Derived from the basic series of Y, adopting measures to strengthen structural seals and materials and process anti-corrosion. Y-W is used in outdoor machinery, Y-F is used in machinery with chemically corrosive media, and Y-WF is used in various machines with chemical corrosion outdoors. Mainly used in petroleum, chemical, fertilizer, pharmaceutical, printing and dyeing enterprises, such as pumps, oil pumps, blowers, exhaust fans and other mechanical equipment.
12. Protective three-phase asynchronous motor
Y-F, JO2-F
13. Outdoor anti-corrosion three-phase asynchronous motor
Y-WF, JO2-WF
14. Marine three-phase asynchronous motor
