　　Three-phase brushless DC motors （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 decreased dramatically and new control algorithms have proliferated. BLDC motors offer high reliability， high efficiency and high power-to-volume ratio. They can run at high speed （greater than 10，000 rpm）， have low rotor inertia allowing for quick acceleration， 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 have similar 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 the air 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.
