Explosion-proof motors generally require an ambient temperature of -20 to 40 °C, a temperature group of T4, and a maximum surface temperature of not more than 135 °C. Will it affect the motor if the ambient temperature exceeds 40°C? The high temperature of explosion-proof motors mainly affects the insulation of motor materials. If the temperature…
As one of the biggest countries in motor production, China has many motor manufacturers with many motor models. You are troubled by many problems of motor selection? This article helps you how to choose the right motor. Meaning of the China electric motor model First of all, we must understand the meaning of the model.…
Compared with the traditional motor casing, the aluminum die-casting casing motor has certain advantages. However, not all motors use aluminum casings. The material of the casing depends on the way the motor is used. For example, large motors generally use cast iron materials. Small motors such as our YE series three-phase asynchronous motors use aluminum…
Vibration is a very critical performance index requirement for motor products, especially for some precision equipment and places with high environmental requirements, the performance requirements for motors are more stringent or even severe. During the production and processing of the motor, the dynamic balance of the rotor, the static balance of the fan, the balance…
Indicators that can reflect the running state of the electrical engine bearing Temperature If the bearing has quality problems, assembly problems, or poor lubrication, it will cause the bearing to heat up and the temperature will exceed the standard. General regulations stipulate that the operating temperature of rolling bearings cannot exceed 95 °C, and the…
The structure of the explosion-proof motor Compared with ordinary motors, the biggest feature of explosion-proof motors is that the junction box, base, end cover, junction box bottom, and cover of the explosion-proof motor are provided with isolation surfaces on their joint surfaces. The setting of these isolation surfaces is no different from that of ordinary…
YE3 and YE4 are two series of Three-phase Asynchronous Motors, which are widely used in industrial and commercial applications. What is YE3 (IE3)? YE3 (IE3) ultra-high-efficiency motor adopts high-permeability and low-loss cold-rolled non-oriented silicon steel sheet. It is the model promoted by the state to replace Y, Y2, Y3, and YX3 series motors. The stipulation…
Variable frequency drive (VFD) technology has the advantages of energy saving, consumption reduction, safety and reliability, and simple design, and is widely used in motor drive control. This paper introduces the working principle and system structure of frequency conversion technology in detail and discusses the application of frequency conversion drive technology in motor control in…
