A waterproof motor includes: a recess () and a shaft tube () disposed upright on one side () of a base (); a waterproof cover () covering the one side () of the base () and having a through holecorrespondingly enclosing the shaft tube () and a protruding portion () correspondingly engaging the recess (), a first space () formed between the waterproof cover () and the one side () of the base (); a first circuit board () disposed inside the first space () and having a plurality of sensors (); a housing () having an opening () and connected to the other side () of the base (); an insulation plate () covering the opening of the housing (), a second space () opposite to the first space () formed between the insulation plate () and the housing ().

Waterproof motor

A fan includes an impeller and an inner rotor motor. The inner rotor motor connects to the impeller and drives it to rotate. The inner rotor motor includes a bushing, a shaft, a magnetic conducting shell, a magnetic element and a stator. The shaft passes through the bushing and is coupled to the impeller. The magnetic conducting shell is coupled to the shaft and telescoped to the bushing. The magnetic element is disposed around outside of the magnetic conducting shell. The stator is disposed around outside of the magnetic element.

Fan and inner rotor motor thereof

A fan includes a fan frame, a front impeller and a rear impeller. The fan frame has a frame body and a plurality of connecting elements. The front impeller has a first bushing disposed at the central portion of the frame body. Two ends of each connecting element are respectively connected with the frame body and the first bushing. The rear impeller has a second bushing partially telescoped into the first bushing.
