What are the characteristics of permanent magnet direct drive motors?

Conventional motors rotate at high speeds and produce beeping sounds, and belts can become eccentric if used for too long. The permanent magnet direct drive motor can avoid these troubles and realize 1:1 transmission between equipment and motor, which makes the equipment compact, less noisy, more environmentally friendly and more professional. Direct drives are suitable for applications requiring low speeds, speed regulation and heavy loads. The main benefits of the improvement include quietness, energy saving, stability, strong power and intelligent transformation. So, the direct drive will bring you a better quality of life.

Short-time high overload permanent magnet synchronous motor electromagnetic heat research

With the development of all-electric technology, electric rudder is widely used in aerospace, military applications and other fields. The rudder system motor requires high power density, high dynamic response and high reliability. Permanent magnet synchronous motors are widely used in rudder servo systems because of their simple structure, high torque density, high power density and high efficiency.

What is the copper wire used in the motor

Electromagnetic wire is divided into two major types of oxygen-free (production of raw materials used for the fine copper rod, copper) low oxygen (the raw materials used for the recycling of old copper wire, old material melted and re-produced) according to its temperature resistance level is also divided into 130 level (temperature resistance level of 130 ℃) 180 level (temperature resistance level of 180 ℃).

Motor energy-saving effect is obvious, the guidelines will be further followed up and implemented

China's motor industry has achieved great results by improving energy efficiency. According to the Ministry of Industry and Information Technology and the General Administration of Quality Supervision, Inspection and Quarantine issued the "national motor energy efficiency improvement program (2013-2015)" proposed by the policy shows that, through the upgrading of motor goods, it is estimated that in 2015, the completion of the current year to save 80 billion kilowatt hours of electricity. And this data is close to the Yangtze River Three Gorges project a year of power generation.
