Service Case: Measure and Analyze the Vibration Issue
Customer S is a Thailand industrial ventilation system manufacturer. They have controversial issue with their previous supplier about the motor noise and vibration for a long time. Because they do not have a proper vibration standard to discuss with their former supplier, can only by the method of hand touch and feel the vibration.
Kuo Shuay tested their existed motor and analyzed the causes of noise and vibration in the UL lab. The motor are carefully tested from three planes (vertical, horizontal, and axial) by the vibration meter. We also had the noises test and analysis in our silent test chamber. By using accurate vibration and noise meter with statistic data and providing a quality control standard, our customer is very satisfied that we can systemically solve the vibration issue and provide trusted report for them.
|1||Efficiency Test||If the motor needs to enter North America, Japan, Europe, China, South Korea, etc., according to local laws and regulations, the motor must meet energy efficiency requirements. Kuo Shuay can provide either certified high-efficiency series products, or design new motors according to customer needs, and test the efficiency by specific methods in the UL laboratory.|
|2||Torque-Speed Curve Test||According to the speed and torque relation, sketch the performance curve, helping customer to know the motor performance at load point 0%, 25%, 50%, 75%, 100%, 125%, 150% and maximum torque. Computer can automatically collect key data such as current, efficiency, torque and speed.|
|3||Temperature Rise Test||One of the most important considerations of the motor is the temperature during operation. Temperature rising test can simulate the loading at customer's end. During the stabilization process of temperature, the computer would record the temperature rising curve, to let the customer know whether the insulation level of the motor meets the temperature requirement or the motor have correctly matched the temperature protection devices.|
|4||Circle Diagram Test||Through the stable and high quality power system in our UL lab, computer can automatically and precisely measure the data of the induction motor, draw the motor circle diagram and further calculate the maximum output, maximum torque, power factor, efficiency and speed, etc.|
|5||Inverter Duty Motor Test||Due to varies test methods, please ask us for further detail.|
|6||Brushless Motor Test||Due to varies test methods, please ask us for further detail.|

Due to the energy saving issue, many governments have started to regulate the energy consumption for motors. According to the IEC 60034 standard, the nominal efficiency for 20HP 4 poles three phase induction motor is 93% at 60Hz, and 92.1% at 50Hz. Compared with IE1 or less efficient traditional motors, the IE3 motor can save more than 5% energy losses. Therefore, significantly electricity cost could be saved for long term use.In order to provide a better efficiency, the motor core uses special electromagnetic steel with excellent insulation and magnetic permeability to achieve a high power density, and significantly reduces the core loss. The motor runs with low temperature rise, and has an IP54 protection. Kuo Shuay could provide certification including UL (North American), BSMI (Taiwan), CE (Europe) and GB2 (China), and have been approved for sale by the US Department of Energy.
The 15HP2P high efficiency squirrel cage induction motor has an aluminum frame and use a smaller motor iron core. Therefore, the weight is lighter than traditional iron cast motor. It follows the international standard IEC60034 and designed for IE3 efficiency equivalent to premium level in North America). Compared to traditional or IE1 motor efficiency (87.5% or less), IE3 efficiency is 91%. It helps our customer saving the energy cost each year. The motor is certificated by UL (North America), BSMI (Taiwan) and CE (Europe), and sold to Europe, America, Japan, Korea, China and many countries.The advantage of Kuo Shuay's high efficiency motor is the wide range of the voltage and frequency cover (200V, 220V, 230V, 240V, 380V, 400V, 415V, 440V, 460V to 480V, with frequency 50Hz and 60Hz). It helps our customer reduces the inventory cost and easier to control their stocks. On the other hand, the motor has three positions of foot mount installation. The terminal box can be rotated 90°, let customers have more flexibility to adjust the cable power entrance and foot mounted position.
20HP three phase AC motor is widely used in various industries. Cast iron frame and TEFC structure provided IP54 protection. High quality double shield ball bearings are pre-lubricated; therefore, the motor is easy maintenance. F class insulation (withstand heat up to 155°C) let the motor have more temperature tolerance and long service life.Motor designed in accordance with IEC60034, has excellent operating performance, and has reached IE3 and NEMA Premium efficiency. Installation dimensions are all international universal specifications, and the motors are interchangeable. 50Hz, 60Hz dual frequency and multi-voltage designs allows customers to reduce their inventory costs. The products have obtained certification including UL (North America), BSMI (Taiwan), GB2 (China) and CE (Europe).
The 15HP IE3 motor, efficiency reaches 91% obtains the Department of Energy from U.S. approval according to the energy regulation 10-CFR 431. The high efficiency can reduce the energy consumption, protect the environment. Recently, many countries have already made the regulation for the energy-saving way. The ANUH series gets the certification from UL (North America), CE (Europe) and BSMI (Taiwan). Applicable voltage includes 200V, 220V, 230V, 240V, 380V, 400V, 415V, 440V, 460V to 480V, frequency 50Hz and 60Hz.The motor adopts a shorter diameter of stator with upgraded electromagnetic steel, increasing the power density. It can maintain the same output, while achieving the IE3 level. In addition, the motor has F class insulation and IP 55 protection. As a professional motor design manufacturer, Kuo Shuay could provide an excellent quality product and offer a more competitive option.
