This paper presents a novel electric brushless DC (BLDC) motor made directly on a printed circuit board (PCB). This PCB-based BLDC motor is ultra-compact, low-cost, high-torque, and compatible with PCB manufacturing process. This new motor structure is specifically designed for motor-on-board sensor systems like LiDARs, camera gimbals, fans, and other smart sensors and actuators. With this technology, the whole motor-on-board system can be highly integrated in a single compact module. The configuration and working principle of this new motor system is presented. A prototype is built and tested to prove this new concept. FEA analysis is presented to help people understand the design process of this system. The experimental results are analyzed and discussed.
