Abstract: A flattened DC brushless motor pump is provided. A first part of a silicon steel sheet unit is attached to a first face of a base plate and a second part of the silicon steel sheet unit is wound with a coil unit so that the coil unit does not overlap the height of a blade member of an impeller so as to reduce the length of a shaft of the impeller, such that the height of a base can be reduced to achieve the advantage of flattening. Thus, the flattened DC brushless motor pump can be hidden in a working machine to reduce the space of use.

Abstract: A permanent magnetic motor with external rotor includes a first housing provided with a foundation plate having its circumference formed integral with a circumferential wall and its interior formed with an accommodating space. Plural permanent magnets are equidistantly and annularly disposed inside the circumferential wall of the first housing, and a second housing to be covered with the first housing has its outer circumference annularly provided with a protruding-up extension portion, which is slightly the same as the circumferential wall in height. Thus, magnetic permeance area can be doubled via the circumferential wall and the extension portion, able to make magnetic conduction smooth and increase output power of the permanent magnet motor with external rotor.

Abstract: A three-in-one control device for a ceiling fan includes a signal receiving module, which is able to receive segmented controlled signals, stepless controlled signals and wireless controlled signals respectively, for transmitting controlled signals to a micro computer control unit to process, analyze and code them. Then, the processed signals are transmitted to a driving unit to drive the blades of the ceiling fan to rotate. Therefore, when a control switch is replaced with another type, it is unnecessary to change the control device but just connect it to a corresponding control module, able to save manufacturing cost.

Abstract: A negative pressure pump device includes a water tank installed with a pump having an entrance connector extended out of the water tank. The water tank has an exit connector and a valve set on its topside. The entrance connector and the exit connector are respectively connected with a connecting tube for connecting with a circulation system. When the pump works with the valve closed, water is filled in the circulation system, the connecting tubes and the pump to make the pressure of a chamber of the water tank become negative, forming a suction force to suck in the water in the entrance connector, not only keeping the pump operate with a less power for saving energy, but also using less the connecting tubes for decreasing possibility of leakage.

The stator includes a central tubular shaft located at its center and bored with a sidewise hole at a preset position for plural wires to pass through, and plural wire wound sets located around its circumference with a number of three's multiple. Each wire wound set is wound by the wire with a preset number of turns via an automatic triple-phase winding means, which can be modified and revised from a conventional automatic winding means. Therefore, the stator can be not only easily made into a small size, but also consume less energy.
