The present invention provides a spindle motor assembly with an encoder. The spindle motor includes a circuit board, a spindle motor and an encoder. A connector is mounted on the upper surface of the circuit board. The spindle motor is provided on the circuit board. The spindle motor functions to rotate a disk placed thereon. The encoder is provided on the connector and senses a detection mark of the disk and thereby detects a rotating speed of the disk. As such, because the encoder is installed on the connector, the number of components is reduced, and the production cost can be thus reduced.
