2013 R&D 100 Winner
Coin Type MotorRadial winding motors are common devices in a variety of electronic products, from micropumps to electronic locks. Mounted on a printed circuit board (PCB), the motors offer performance based on the thickness of their coils. Traditional designs experience power loss when less than 3 mm thick, a disadvantage that limits design possibilities. Engineers at Metal Industries Research and Development Centre have introduced a new axial flux motor design in its Coin Type Motor that integrates a kite pattern stator coil and drive circuitry into the PCB. This helps reduces the motor thickness without losing power. Measuring 12 by 2.5 mm, the slotless brushless motor module is powered by 3-V DC and can be constructed using a single surface-mount fabrication process. Performance and efficiency exceeds current technology by 25%.
