Steering control is a key to motor manufacturing
For most motors, in the absence of special regulations, rotate in a clockwise direction, that is, after wiring according to the terminal mark of the motor, it should rotate in a clockwise direction when viewed from the motor shaft extension end; motors that are different from this requirement , s...Read more -
What performance does the dust shield affect the motor?
The dust shield is a standard configuration of some wound motors and motors with relatively low protection levels. Its main purpose is to prevent dust, especially conductive objects, from entering the inner cavity of the motor, resulting in unsafe electrical performance of the motor. In the namin...Read more -
Why can’t general motors be used in plateau areas?
The main features of the plateau area are: 1. Low air pressure or air density. 2. The air temperature is low and the temperature changes greatly. 3. The absolute humidity of the air is small. 4. The solar irradiance is high. The oxygen content of the air at 5000m is only 53% of that at sea leve...Read more -
Can the level 1 energy efficiency stipulated in the new version of GB18613 allow China’s motors to stand at the highest level of international motor energy efficiency?
It is learned from the national professional authority that the GB18613-2020 standard will soon meet with motor manufacturers and will be officially implemented in June 2021. The new requirements of the new standard once again reflect the national control requirements for motor efficiency indicat...Read more -
What are the mandatory standards for motor products?
0 1 The current mandatory national standard (1) GB 18613-2020 Allowable Values of Energy Efficiency and Energy Efficiency Grades of Electric Motors (2) GB 30253-2013 Permanent Magnet Synchronous Motor Energy Efficiency Allowable Values and Energy Efficiency Grade Standards (3) GB 3025...Read more -
The specific performance of the frequency conversion motor is different from that of the ordinary motor
Ms. Shen’s best friend HH doesn’t like summer very much. The first reason is that HH ’s sweat glands are special, and basically does not sweat on hot days, so it feels particularly uncomfortable; the second reason is that HH ’s mosquito relationship is particularly good, and sometimes...Read more -
Knowledge in motor manufacturing: How much bearing clearance is more reasonable? Why should the bearing be preloaded?
Bearing system reliability is always a hot topic in electric motor products. We have talked a lot in previous articles, such as bearing sound problems, shaft current problems, bearing heating problems and so on. The focus of this article is the clearance of the motor bearing, that is to say, unde...Read more -
High-efficiency, energy-saving and consumption-reducing control of motor frequency conversion and speed regulation
The frequency conversion and speed regulation operation of the motor has gradually become a symbol of the times. The speed regulation of the synchronous motor is the frequency conversion and speed regulation control of the square torque load machinery such as the fan and the pump driven by the fr...Read more -
Coaxiality Requirement and Realization of Motor Frame
The frame is a very critical part of the motor. Compared with parts such as end covers, since the iron core is pressed into the frame, it will become a component that is not easy to disassemble. Therefore, people should pay more attention to the quality compliance of the frame. Some. The diamet...Read more -
Motor quality problems caused by unsuitable bearings
Motor bearings are always the most discussed topic in motor products. Different motor products need corresponding bearings to match them. If the bearings are not selected properly, there may be problems such as noise and vibration that directly affect the performance of the motor. impact on servi...Read more -
The random inspection of the whole motor is generally not disassembled for inspection
Quality supervision and random inspection is a means for the country to supervise and inspect product quality from different levels and scopes, and motor products are no exception; but from the entire development process of motor product quality supervision and random inspection, motor quality ra...Read more -
When the direction of the left, right, and top outlets of the motor changes, will it affect the rotation of the motor?
The direction of rotation is one of the important quality properties of motor products. If the customer has no special requirements, the motor manufacturer will manufacture it in a clockwise direction, that is, after wiring according to the phase sequence marked on the motor, the motor should rot...Read more
