An electric motor is a device that converts electrical energy into mechanical energy. It uses an energized coil (that is, the stator winding) to generate a rotating magnetic field and acts on the rotor (such as a squirrel-cage closed aluminum frame) to form a magneto-electric rotating torque.
Motors are divided into DC motors and AC motors according to different power sources. Most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors (the stator magnetic field speed of the motor does not maintain the same speed as the rotor rotation speed).
The following is an introduction to the world's seven major motor manufacturing powers:
1
Germany
Germany is a respectable craftsman-style technological developed country. German manufacturing was once known as the "factory of many factories" and was the manufacturer of the world's factories. It is worth mentioning that among the 31 sectors of Germany's machinery manufacturing industry, 27 once occupied a leading position in the world, and a total of 17 sectors were in the top three. For example, Germany leads the world in manufacturing industries such as steel, chemicals, machinery, and electrical appliances. In particular, Germany has given birth to a number of world-renowned companies such as Volkswagen, Daimler, BMW, and Siemens. According to incomplete statistics, Germany, with a population of just over 82 million, has an astonishing number of more than 2,300 world-famous brands.
German motor manufacturing technology is at the top level in the world. The outstanding features of motor manufacturing are: exquisite craftsmanship, excellent and reliable quality, and scientific and perfect design. In particular, the vibration, noise and performance of the motor are quite reliable. For example, the efficiency of German motors in Europe SHCORCH is considered to belong to the eff`1 level (the highest level of efficiency), which is the highest standard of high-efficiency motors. Its competitors are only second tier. Its brand is recognized by many OEM manufacturers and engineering companies in Europe and the United States.
Germany has many top motor manufacturing giants. For example, the German Flanders Group is one of the largest professional power transmission equipment manufacturers in the world. It was founded in 1899 and is headquartered in Bocholt, Germany. It has a century of manufacturing experience. For a hundred years, it has occupied a leading position in the world's drive industry with its strong technical resources, leading manufacturing technology and excellent product quality. Produces reducers, couplings, gear motors and electric motors for various purposes.
Important German motor manufacturer
Siemens: the world's leading motor manufacturer. From construction technology and automation equipment for manufacturers and construction companies, to imaging and diagnostic systems for hospitals, and electric motors for industrial and mobile purposes, Siemens seems to be everywhere. Since its founding more than 150 years ago, Siemens has grown into one of the world's leading electric motor manufacturers.
Germany (Lenze) Lenze Motor: Since the establishment of Lenze in Germany in 1947, drive and automation systems have always been Lenze's core competitiveness, making Lenze one of the most innovative companies in the industry. Lenze Group can also provide customers with a complete product system at all stages of machinery development and is one of the few such suppliers on the market.
Schorch, Germany: The company was founded in 1882 and is one of the world's famous motor manufacturers. Due to its high-quality technological innovation and outstanding product quality, SCHORCH motors were once acquired by the international motor manufacturing giant and later acquired by the AEG Group. AEG produces Many of our high-power special motors are OEM-produced by SCHORCH factories. SCHORCH motors can be seen in many major and influential projects around the world. SCHORCH has had good relationships with many well-known enterprises and engineering companies in these fields for decades in supporting product supply and project cooperation. SCHORCH motors have gained the full trust of users. , for example, the Anglo-Dutch Shell (SHELL) has designated the SCHORCH brand in the selection of high-power motors for many of its global investment projects, including many projects in developed countries.

Japan
Japan has the world's leading top motor manufacturing technology. Japan has always been a strong country in robotics, so Japan's servo motor industry is also the top in the world. According to previous global market survey reports by research institutions, Japanese companies account for 50% of the market and occupy half of the entire robot motor industry.
Since the 1980s, Japan has been the country with the most robots in the world! For example, Nidec Motor Company once ranked first in the world, with annual revenue of 97 billion from one motor. Don't you know that when Nidec was founded, there were only four young people. In just ten years, Nidec became the world's number one in the field of drive motors. After that, Nidec acquired more than 50 companies around the world, eventually becoming today's "global integrated electromechanical product manufacturer."
Nidec's precision small motors have been outstanding in the world since 2010. Especially in 2020, Nidec has blossomed into three categories (precision small motors, automotive and home appliances, and industrial and commercial motors). It can be said that Nidec has transformed motors into Armed to the teeth, maintain a domineering share of global production. By 2001, Nidec was listed in New York, USA, and then successfully listed in Osaka, Tokyo, and achieved further development. Nidec has become the world's leading industry in many fields. For example, its brushless DC motors occupy a global monopoly. Moreover, Nidec has expanded from a small company of four people to more than 96,000 people, realizing its ambition to be the world's number one. At present, Nidec has a new development direction-electric vehicle parts. Its orders for pure electric vehicle drive motors have surged significantly.
Japanese motor manufacturers in the field of intelligent manufacturing control global high-end technology and occupy a very important position in the global motor market. Japanese motors are almost all at the top of the market and have the top technologies and products in the global industry.
Japan has carried out a lot of research and development work on the high efficiency and quietness of permanent magnet motors, and the high performance of permanent magnet motors for industrial servos. Therefore, it has a great leading edge in technology. The micro motor equipment produced in Japan has high control It has competitive advantages such as precision, low power consumption, long life, low cost and small size, and is also at the forefront of the world's technology, occupying most of the world's high-end permanent magnet motor market.
