Due to the advancement of power electronics and drive systems, special electric machines were introduced, and the Brushless DC motor is one of them. An electronic controller is used to switch DC currents of the stator windings producing magnetic fields which effectively rotate in space and which the permanent magnet rotor follows. Researchers have moved towards Brushless DC (BLDC) from traditional brushed motors to take advantage of the power efficiency, torque efficacy, size, and reliability benefits. It is suitable for many applications such as robotics, drones, automobiles, and even aircraft. In this context, a special interest is paid to the concentrated windings that allow more compact designs and more efficient topologies as they are known by shorter end windings.
In this webinar, we will show you step-by-step, how to use our virtual prototyping EMWorks2D software, to study and perform two BLDC motor designs with 16 and 20 poles under different commutation conditions (120° and 180° conduction mode). The electromagnetic results such as back EMF, flux linkage, and average torque as well as thermal analysis will be evaluated and analyzed. In addition, we will demonstrate how to build and simulate the BLDC motor using our electromagnetic simulation software tools – EMWorks2D
