Abstract: The present invention provides a motor including a base, a winding assembly and a rotor. The base includes a pivoting portion. The winding assembly includes a support. The support includes at least one coil supporting portion and a circuit supporting portion connected to the at least one coil supporting portion. A coil is arranged on each of the at least one coil supporting portion. A circuit is arranged on the circuit supporting portion and electrically connected to the coil or coils. A folding portion is arranged between the at least one coil supporting portion and the circuit supporting portion. The circuit supporting portion and the at least one coil supporting portion are folded and stacked together via the folding portion. The rotor is rotatably coupled to the pivoting portion of the base. Due to the arrangement of the folding portion, a radial width of the motor is efficiently reduced.

Abstract: The present invention provides a motor winding assembly including a flexible base plate and a winding assembly. The flexible base plate includes a plurality of supports. A bridge is connected between adjacent two of the plurality of supports. Each of the plurality of supports has a center, and the flexible base plate has a reference line extending through the centers of the plurality of supports. The bridge is not located on the reference line. The winding assembly includes a plurality of winding units. Each of the plurality of supports is provided with at least one winding unit. An electrical path is located on the bridge between the adjacent two of the plurality of supports and electrically connected to the winding units of the adjacent two of the plurality of supports. In this arrangement, the total length of the flexible base plate is reduced.

Abstract: A sensorless three-phased brushless direct current (BLDC) motor comprises a stator, a rotor and a driving unit. The stator has a first-phased coil, a second-phased coil and a third-phased coil. Each of the first-phased, second-phased and third-phased coils has a varying inductance value. The varying inductance value has an inductance changing rate greater than 15%. The rotor has a plurality of magnetic poles, each having a magnetic pole face facing the stator. The driving unit has a power input end and a signal input/output end. The signal input/output end is coupled to the first-phased, second-phased and third-phased coils, and the power input end is used to receive power for maintaining operation of the driving unit.

Abstract: A lamp with power supply detection includes a power supply unit, a control module and a lighting module. The power supply unit provides a direct current (DC) voltage. The control module is coupled to the power supply unit, receives and stores the DC power, and generates a control signal according to whether the DC power is terminated or regained. The lighting module is coupled to the power supply unit and the control module, receives the DC power and adjusts brightness of the lighting module according to the control signal.
