Abstract: A guiding grid is disclosed and includes plural circumferential elements and plural radial elements. The circumferential elements are disposed concentrically relative to a central axis, spaced apart from each other in a radial direction, and form different heights relative to a bottom surface. One of the circumferential elements forms a top height relative to the bottom surface, so that the circumferential elements are divided into an outer-ring region and a central region in the radial direction. The circumferential elements located in the central region are increased in height relative to the bottom surface along the radial direction. The circumferential element located in the outer ring region are reduced in height relative to the bottom surface along the radial direction. The radial elements are connected between each of two adjacent circumferential elements. At least one of the radial elements is misaligned and discontinuous in the radial direction.

Abstract: The present disclosure provides a motor including a stator, a rotor and a first circuit board. The stator includes a winding assembly including a plurality of coils. A conductive element is extended out from the winding assembly and is electrically connected to a first electrical connector. The first electrical connector penetrates through a pillow of the stator and is electrically connected to the first circuit board. The motor further includes a second circuit board electrically connected to the first circuit board, and a first insulation plate, a second insulation plate and a third insulation plate for fixing and protecting the circuit boards. The motor also includes a clip for fixing and heat dissipating an electronic component disposed on the second circuit board.

Abstract: The present disclosure provides a motor including a base, a stator and a rotor. The stator is disposed on the base. The base includes a cylinder. There is a flange disposed on a side of the cylinder neighboring to the rotor. Fins are axially disposed on the flange, and the periphery of the flange has a breach. The breach is partially extended to the cylinder, and there is also a plurality of fins disposed in the breach. A plurality of air-guiding members are annularly disposed on the periphery of the rotor. The air-guiding members are connected to each other through a connecting rim. The fins on the flange and the air-guiding members of the rotor are both extended axially, thus the interference therebetween is avoided. When the motor rotates, the air-guiding members are able to drive the flow passing through the breach for achieving heat-dissipating effect.

Abstract: The present disclosure provides an external rotor motor including a rotor, an air guider, a pillow and a stator. The rotor includes a hub. The air guider includes a connecting ring and rotor air-guiding members. The connecting ring is disposed on the hub. The rotor air-guiding members are disposed on the connecting ring. A first gap is formed among any two adjacent rotor air-guiding members and the connecting ring. The pillow includes a stator flange, a cylinder and fins. The stator flange is disposed on the cylinder. The fins are radially arranged on a first surface of the stator flange. A second gap is formed among any two adjacent fins and the stator flange. A first acute angle is formed between a radial extension direction of each of the fins and a first tangent direction of the cylinder. The stator is mounted on the pillow and rotates along an axis.
