motor performanceSiemens Motor (SIEMENS Motor) Siemens is the world's leading motor manufacturer with more than 100 years of motor manufacturing experience. Siemens motor products cover motors that can be used in almost all industrial fields. No matter what kind of load you need to drive, Siemens motors can meet the specific requirements of the system.
Higher efficiency grades reduce energy consumption, which directly saves users costs!
Higher protection level (IP55) ensures safe and reliable use by customers!
High cost performance, customers can enjoy high-quality, good reputation international brand products at a low price, which provides a guarantee for customers' use and indirectly saves costs for users.
——Flexible outlet: the junction box can be rotated in 4*90 degrees, and the customer can specify it arbitrarily, just specify it when ordering.
——Sturdy component connection: implement Siemens motor assembly standard, modular design, modular installation, improve the reliability of component connection, greatly reduce the installation and commissioning time, and shorten the delivery time.
——High-performance protection level: All motors are designed with IP55 protection level. They can be used outdoors or in dusty and humid environments. Users do not need to add additional devices without affecting normal use. And it can also provide a higher protection level according to user requirements.
——Improve the insulation performance and increase the service life of the motor: all standard motors adopt F-class insulation system, and are assessed according to B-class insulation, which increases the reliability of the motor operation and the life of the motor, and can provide more according to user requirements High insulation class.
——Excellent rotor processing technology: After each rotor is processed, it will be properly protected and coated with protective paint.
——Selection of high-performance bearings and lubricating grease: The bearings are selected from famous brand manufacturers and customized according to Siemens requirements. The grease is selected from Esso Unirex N3 new lubricating grease, which is resistant to high temperature and is not volatile, ensuring the continuous and long-term reliable operation of key components;
——Wide voltage, wide frequency: the actual voltage can be within the rated voltage.
Machine advantages
1. High efficiency level reduces energy consumption, which directly enables users to save costs
2. High protection level (IP55) to ensure safe and reliable use by customers
3. High cost performance.
Application industry

Pump load (fixed speed and variable torque load speed regulation)
Compressor load (fixed speed and variable torque load speed regulation)
When the pulse voltage is transmitted on the cable, if the impedance of the cable does not match the impedance of the load, reflection will occur at the load end. The result of the reflection is that the incident wave and the reflected wave are superimposed to form a higher voltage, and its amplitude can reach twice the DC bus voltage at most, which is about three times the input voltage of the inverter, as shown in Figure 3 . Excessive peak voltage is added to the coil of the motor stator, causing a voltage shock to the coil, and frequent overvoltage shocks will cause the motor to fail prematurely.
After the motor driven by the frequency converter is impacted by the peak voltage, its actual life is related to many factors, including temperature, pollution, vibration, voltage, carrier frequency, and coil insulation process.
The higher the carrier frequency of the inverter, the closer the output current waveform is to a sine wave, which will reduce the operating temperature of the motor and prolong the life of the insulation. However, a higher carrier frequency means that the number of peak voltages generated per second is greater, and the number of shocks to the motor is greater. Figure 4 shows the insulation life as a function of cable length and carrier frequency. It can be seen from the figure that for a 200-foot cable, when the carrier frequency is increased from 3kHz to 12kHz (a change of 4 times), the life of the insulation decreases from about 80,000 hours to 20,000 hours (a difference of 4 times).
We are a professional sales agent of world-renowned brands of welding machines, frequency converters, vacuum pumps, fluid equipment, counters, instruments, pumps, valves and other dynamic products. The imported spare parts we sell are purchased directly from other manufacturers, and the flat sales model is implemented, which saves time and cost for customers. Our goal is that domestic users can find us when they encounter difficulties and difficulties in purchasing foreign spare parts. We are able to offer favorable prices and fast delivery in a timely manner; when domestic users purchase foreign spare parts at prices monopolized by an exclusive agent, we will provide users with a chance to compare and provide customers with the best solution. Because our orders are concentrated and the order quantity is large, we can provide quite competitive prices and deliver quickly. We have long been committed to solving difficult problems in domestic users purchasing foreign spare parts
