1, structural differences, brushless DC motors usually rotor poles using tile magnets, after the magnetic circuit design, you can get trapezoidal wave of air gap magnetic density, stator winding more concentrated whole pitch winding, so the induction counter-electromotive force is also trapezoidal wave. Brushless DC motor control requires position information…
1. What do you mean by electric motor? Motor is the part that converts battery electric energy into mechanical energy and drives the wheels of electric vehicles to rotate. 2. What is winding? Armature winding is the core part of a DC motor, which is a coil wound by copper…
With public health and safety a top priority in our daily lives, automatic door locks are becoming increasingly popular, and these locks need to have sophisticated motion control. Miniature precision stepper motors are the ideal solution for this compact, sophisticated design. Automatic door locks have been around for some time,…
When the drones sent express delivery and take-outs were still in a promotional video, China’s take-away industry was ahead of the world. At this year’s World Unmanned Systems Conference, the hungry take-out drone “E7” (Chinese name: Wing) made its debut publicly. The E7 has a maximum flight speed of 65…
DJI and the United States have relapsed into security issues. In the latest memo leaked a few days ago, the US Immigration and Customs Enforcement Agency pointed out that DJI is using its drone products to conduct espionage activities for the Chinese government in the United States. Its drones and…
Employee empowerment will be one of several key components helping the company meet its growth goals, Rohr says.
