It is well known that the direct drive systems not to use the reduction gears with the clearane and backlash are required for the highly precise position control, whose motor must have high torque at very low speed. The authors have developed a new motor for this purpose and named PM vernier motor.In this paper, it is explained at first what is PM vernier motor, the construction and principle, and then the theory able to calculate the torque and how to control its speed are described. It is also shown that the calculated values of torque were agreed well with the experimental results.
