Single sided Brushless DC (BLDC) drives with axial flux have the advantage of a flat design and high torque. This makes them a good choice for operating less invasive implantable Ventricular Assist Devices (VADs), which can be applied for the therapy of cardio vascular diseases. The disadvantage of such drives is the occurrence of high axial forces. In order to avoid axial forces some VAD drives have air gap windings. Their torque generation completely relies on magnetic stray fluxes. Therefore… CONTINUE READING
