BLDC Motor Winding: Materials, Design, Manufacturing and Testing
Introduction The winding is one of the most important parts of a brushless DC motor. Even when the stator core, permanent magnets and mechanical dimensions remain unchanged, different winding designs can significantly change motor speed, torque, current, efficiency and thermal performance. Wire diameter, number of turns, winding layout, slot/pole combination, phase connection and manufacturing process…
BLDC Stator Insulation: Coating, Plastic Bobbin and Slot Paper
Introduction The insulation between the stator core and enamelled copper wire is a small part of a BLDC motor, but it can have a major impact on motor reliability, copper fill factor, assembly, and thermal performance. This stator winding insulation must provide reliable electrical separation without unnecessarily reducing the available space for copper. When we…
