Abstract: An interior-permanent-magnet motor structure includes an air gap having the form of an annular band. The air gap is positioned between the stator and the rotor. The width of the annular band of the air gap has a maximum value and a minimum value within each pole pitch range. Accordingly, the air gap magnetic flux is nearly in sine wave state.

Abstract: An industrial robot includes an actuator and a driver. The actuator serves to provide power inside so as to create a predetermined motional form. The driver serves to drive an internal power source of the actuator to output power. The driver is adjacently and fixedly connected with one end of the actuator. A power unit is disposed in the actuator for generating power. The power unit has an output shaft. The actuator has a transmission unit for transmitting the power to make an operation unit move in the predetermined motional form. The transmission unit has a transmission shaft. The output shaft and the transmission shaft are coaxially and integrally formed.
