摘要： A fluid driving device, a motor assembly and a centrifugal friction clutch thereof are provided. The centrifugal friction clutch includes: a fixing member (20) for being fixed on a rotary shaft (11) and comprising a guiding groove disposed in a radial direction of the fixing member (20) and passing through an outer circumferential surface of the fixing member (20); a centrifugal block (24) disposed in the guiding groove and slidable in the guiding groove; and a loading wheel (26) having an inner hole (261) in which the fixing member (20) is received. A gap between a wall of the inner hole (261) and the outer circumferential surface of the fixing member (20) is less than a length of the centrifugal block (24) along its sliding direction. The centrifugal friction clutch reduces vibrations at startup of the motor, thereby effectively reducing the vibrational noise. In addition, this also avoids the startup failure of the motor and effectively improves the startup performance of the motor.

The stator core (30) includes an outer ring portion (31), teeth (33) extending inwardly from the outer ring portion (31), and two pole shoes (35) extending from a distal end of each tooth (33). A winding slot is formed between each two adjacent teeth (33).

The air supplying unit (710) includes the single phase motor (10) and an impeller (711). The startup angle and cogging torque of the motor (10) are adjustable by adjusting the position/width of the slot opening (37), without the need of additional positioning slots or positioning holes defined at the pole shoes (35), which makes the motor structure simple.

摘要： The present teaching relates to a magnetic sensor (1105) including an input port (1102, 1104) and an output port (1106) and an electrical circuit (1100) which includes a magnetic field detecting circuit (1130), an output control circuit (1120), a state control circuit (1140) coupled with the output control circuit (1120) and configured to determine whether a predetermined condition is satisfied and signal the same to the output control circuit (1120). When the predetermined condition is satisfied, the state control circuit (1140) is at least responsive to the magnetic induction signal to enable the output control circuit (1120) to control the magnetic sensor to operate in at least one of a first state and a second state. In the first state, a load current flows in a first direction from the output port (1106) to outside of the magnetic sensor. In the second state, a load current flows in a second direction opposite of the first direction from outside of the magnetic sensor into the magnetic sensor via the output port (1106). When the predetermined condition is not satisfied, the state control circuit (1140) enables the output control circuit (1120) to control the magnetic sensor to operate in a third state.
