Brushless DC pump with enclosed circuit board |
摘要 |
A motor-driven pump including a pump housing; a brushless motor mounted in the pump housing; pump means mounted in the pump housing and adapted to be driven by the brushless motor; and a circuit package mounted in a liquid passage defined in the pump housing, the circuit package enclosing a circuit board mounting thereon a control circuit for controlling rotation of the brushless motor and means for detecting a rotor position of the brushless motor, wherein the circuit board is fixed through an elastic member to an inner wall of the circuit package with a gap defined between the circuit board and the inner wall, and the circuit package is opposed to the brushless motor at a position where the circuit board is spaced a distance from the brushless motor in an axial direction of a rotating shaft of the brushless motor.
