摘要:
A medical pump includes a single phase synchronous motor, a rod piston, a cylinder for receiving the rod piston for reciprocating motion therein. The single phase synchronous motor includes a stator and a rotor rotatable relative to the stator. The rotor includes a plurality of permanent magnets. The stator comprises a stator core and a winding wound around the stator core. The stator core comprises two opposed pole portions that define there between a rotor receiving space for receiving the permanent magnets. The medical pump has a compact structure. In addition, the motor of the medical pump has a constant rotation speed and has a smaller size and less weight under the same output power conditions as traditional motors used in medical pumps. The medical pump is particularly suitable for use in atomizers.
