　　无刷直流电机（BLDC）、永磁同步电机（PMSM）现在在许多应用的青睐，但控制软件运行可以是艰巨的实施。Kinetis电机套件NXP的桥梁的差距与嵌入式控制软件，减少软件的复杂性和加快发展过程中的一个直观的图形用户界面。

　　本文将提供一个简短的介绍BLDC和永磁同步电机电机的建设和关键操作参数，才进入如何驱动他们。然后，它将讨论为什么软件是复杂的，如何管理，和一些硬件选项。然后看看如何获得项目和NXP的Kinetis电机套件运行。

　　Three-phase brushlessDCmotors （BLDC） and their close cousins， permanent magnet synchronous motors（PMSMs）， have become industry workhorses in the last decade as the cost of their control electronics has decreaseddramatically and new control algorithms have proliferated. BLDC motors offer high reliability， high efficiency and high power-to-volume ratio. Theycanrun at high speed （greater than 10，000 rpm）， have low rotor inertia allowing for quickacceleration， deceleration and quick reverse， and have high power density， packing a lot of torque into compact sizes. Today， they are used in any number of applications， including fans， pumps， vacuums， quadcopters and medical devices， to name just a few.

　　PMSMs havesimilar construction to the BLDC with a wound stator and permanent magnet rotor， but the stator construction and winding is more similar to an AC induction motor， producing a sinusoidal flux density in theair gap. PMSMs run synchronously with the applied 3-phase AC voltage and have higher power density than AC induction motors because no stator power is going towards inducing the magnetic field in the rotor. Today’s designs are also more powerful while having a lower mass and moment of inertia， making them attractive for industrial drives， traction applications and appliances.
