A position sensing device for a motor, the motor has a stator having a coil winding, and a rotor, and the position sensing device including a fixing frame, including a first fixing portion, a second fixing portion, a third fixing portion, and a fourth fixing portion, multiple Hall components, and a PCB board. The position sensing device is connected to the stator via the first fixing portion whereby detecting a position of the rotor, the second fixing portion operates to fix a power lead connected to the coil winding of the stator, the PCB board is disposed on the fixing frame via the third fixing portion, and the Hall component is disposed on the fixing frame via the fourth fixing portion and connected to the PCB board. The invention features simple structure and is capable of being firmly connected and fixed to other electronic components such as a power lead, a PCB board and so on.
