Nowadays, the reduction of size and weight is very often one of the most important requirements in product design. Many applications in robotics, automation, medicine systems etc require powerful precison actuator. The powerful precision actuator has Speeds up to high speed and high output torque efficiencies. To accomplish a powerful precision actuator, these powerful motor have to be combined with gearhead of the same outer diameter. So, we have developed BLDC motor and planetary type gearheads as powerful precison actuator. The BLDC motor has advantages that compact structure, high efficiency, high reliability. The planetary type gear heads have advantages that same-axle structure, high torque transmission, low noise in comparison with spur gear heads. In this study included BLDC motor and planetary type gear heads design, manufacture for small robot.
