The Industrial Type Air Cooler Motor from Shengzhou Jiangxin Motor Technology Co., Ltd. is a motor series for industrial air coolers. The air cooler provides cooling and also ventilation, dust removal and odor removal, and it is described as popular equipment for factory workshops, public places and commercial entertainment venues. Jiangxin produces the motor with 100 percent copper windings and class E insulation.

Models and Parameters

The product page lists five models. The YY90-4 has a rated output of 1.1 kilowatts, a 220 volt single-phase supply, 1400 revolutions per minute and 7.41 amps. The SY90-4 has 1.5 kilowatts, a 380 volt single-phase supply, 1400 revolutions per minute and 2.62 amps. The YY140-6 is listed in three versions: 0.39 kilowatts at 750 revolutions per minute and 2 amps, 0.5 kilowatts at 850 revolutions per minute and 2.5 amps, and 0.75 kilowatts at 910 revolutions per minute and 3.1 amps, all on a 220 to 240 volt single-phase supply.

The table also lists a locked rotor torque of 0.32 for the YY90-4, 0.3 for the SY90-4 and 0.33 for the YY140-6 versions, a breakdown torque multiple of 1.7, and a locked rotor current multiple of 30, 45, 20, 20 and 30 for the five rows. The buyer should confirm the model, the voltage, the speed and the shaft details against the fan or cooler being built.

The table is a guide, not a complete specification. The buyer should ask for the mounting dimensions, the shaft diameter, the shaft length, the flange or foot pattern, the capacitor if required, the insulation class, the protection level and the duty rating. A motor that fits the cooler frame but has the wrong shaft or speed can cause noise, vibration or poor airflow.

Construction

The motor uses 100 percent copper windings and class E insulation. The page states that the design gives high voltage and over-current stability and stable operation. The body is aluminum and fully sealed, with anti-seepage water, anti-rust and anti-corrosion ability, fast heat dissipation and a stable temperature rise. Those features are useful in a workshop or a humid environment where the motor may be exposed to dust and water.

The sealed aluminum body helps protect the windings, but the buyer should still confirm the protection level and the installation position. A motor mounted in the air stream may see more dust and moisture than one mounted outside the cabinet. The buyer should also confirm the bearing type and the expected maintenance interval.

The page mentions overload use. The buyer should not treat that as a license to run the motor beyond its rating; the actual load, the ambient temperature and the duty cycle should be checked. A motor that runs hot will have a shorter life even if it has a class E insulation system.

Applications

The motor is used in industrial air coolers, evaporative coolers, ventilation fans and similar cooling equipment. Jiangxin's wider range includes external BLDC air cooler motors, window type air cooler motors, permanent magnet air cooler motors, oil pump motors, heater series, cattle house fan motors, negative pressure fan motors and fiberglass fan motors. A buyer who needs several motor types can discuss the full list with one supplier.

For a factory workshop, the motor should be matched to the air volume and the static pressure of the cooler. For a public place or a commercial venue, the noise level and the appearance may matter more. The buyer should state the application so that the supplier can recommend the speed and the winding.

The product page does not list the efficiency class or the certification. The buyer should ask for the test report and the certificate required for the destination market, especially for a product that will run for long hours.

Ordering Notes

The order should state the model, the rated output, the voltage, the frequency, the speed, the shaft, the mounting, the protection level and the quantity. The buyer should also confirm the lead time, the packing and the documents. A sample or a small trial order is the practical way to check the fit, the noise and the temperature rise.

Jiangxin can be contacted through the telephone and email shown on the product page. The buyer should send the cooler drawing and the required airflow so that the supplier can recommend the motor.

The Industrial Type Air Cooler Motor is one part of a cooling system, and the result depends on the motor, the fan, the housing and the installation. A correct match is more valuable than a low price per unit.
