Abstract
A direct drive type system such as a direct drive type robot is provided. This system includes a rail member, a movable member guided by the rail member and movable along the rail member, and an electric motor to drive the movable member. The system includes a transmission coil and a reception coil. The transmission coil has plural transmission coil segments which are planar coils and arranged on and along the rail member. High-frequency power is supplied to the transmission coil from a power source. The reception coil is arranged on the movable member to be opposed to the transmission coil and configured to an area faced with each of the transmission coil segments, wherein the area is smaller than that of each transmission coil segment. The reception coil receives power from the transmission coil without contact by a magnetic resonance. The received power is supplied to the motor.
