Micro motors are widely used in robotics. Our Micro motor is small size, light and high energy output. They are excellent for powering the drive wheels of a mobile robot as well as powering other mechanical assemblies. Our Micro motor, the smallest size is 4mm diameter, is one of our new development which is an ongoing process intended to continuously improve performance and convenience. It is suitable to be used for R/C toys such as helicopter, tiny R/C cars, robots, and remote control models.
