How does the motor manufacturing industry choose qualified suppliers?
Quality is often touted and often referred to as a cliché, and even when it’s used as a buzzword, many engineers throw the idea out of the way before delving into the situation. Every company wants to use this word, but how many are willing to use it? Quality is an attitude and a way of lif...Read more -
Which motors use rain caps?
The protection level is an important performance parameter of motor products, and it is the protection requirement for the motor housing. It is characterized by the letter “IP” plus numbers. IP23, 1P44, IP54, IP55 and IP56 are the more commonly used protection levels for motor product...Read more -
Three Ways to Reduce Motor Weight and Improve Efficiency
Depending on the type of system being designed and the underlying environment in which it operates, motor weight can be very important to the overall cost and operating value of the system. Motor weight reduction can be addressed in several directions, including universal motor design, efficient ...Read more -
The efficiency of the motor cannot be evaluated only by the magnitude of the current
For motor products, power and efficiency are very critical performance indicators. Professional motor manufacturers and test institutions will conduct tests and evaluations in accordance with corresponding standards; and for motor users, they often use current to evaluate intuitively. As a result...Read more -
Permanent magnet motor saves 5 million yuan a year? It’s time to witness the “miracle”!
Relying on the Suzhou Metro Line 3 project, a new generation of permanent magnet synchronous traction system developed by Huichuan Jingwei Railway has been operating in Suzhou Rail Transit Line 3 0345 vehicles for more than 90,000 kilometers. After more than a year of energy-saving verification t...Read more -
A “black technology” motor that is more energy-efficient than rare earth permanent magnet motors?
A “black technology” motor that is more energy-efficient than rare earth permanent magnet motors? The “stand out” synchronous reluctance motor! Rare earth is known as “industrial gold”, and it can be combined with other materials to form a variety of...Read more -
Is the remanufacturing of the motor the same as refurbishing the motor?
An old product is processed by a remanufacturing process, and after strict inspection, it reaches the same quality as a new product, and the price is 10%-15% cheaper than the new product. Are you willing to buy such a product? Different consumers may have different answers. Change the old conc...Read more -
Discussing the Basic Selection Control of Electric Motors from Accident Cases
A motor manufacturer exported a batch of motors. The customer found that several motors could not be installed during installation. When the pictures were sent back on site, some assemblers could not understand them. It can be seen how important the unit is to the education and training of employ...Read more -
Motor lecture: Switched reluctance motor
1 Introduction The switched reluctance motor drive system (srd) consists of four parts: switched reluctance motor (srm or sr motor), power converter, controller and detector. The rapid development of a new type of speed control drive system developed. The switched reluctance mo...Read more -
Why does the winding of the three-phase motor burn out when the phase is missing? How much current can star and delta connections be made?
For any motor, as long as the actual running current of the motor does not exceed the rated motor, the motor is relatively safe, and when the current exceeds the rated current, the motor windings are in danger of being burned. In three-phase motor faults, phase loss is a typical type of fault, bu...Read more -
Why is the shaft extension diameter of the multi-pole low-speed motor larger?
A group of students asked a question when they visited the factory: Why are the diameters of the shaft extensions obviously different for two motors with basically the same shape? Regarding this content, some fans have also raised similar questions. Combined with the questions raised by fans, we ...Read more -
The future of the motor will be “brushless” after all! The advantages and disadvantages, function and life of brushless motors!
Summary Brushless DC motors have flooded into various industries like a mad wave, becoming a well-deserved rising star in the motor industry. Can we make a bold guess – in the future, the motor industry will enter the “brushless” era? Brushless DC motors do not have brush...Read more
