摘要： A sleeve unit for a motor of a ceiling fan includes a tubular member and a wire isolation member. The tubular member has a lateral slot extending through the tubular member from an inner periphery to an outer periphery of the tubular member. The lateral slot extends from a first axial end face towards a second axial end face of the tubular member along an axis of the tubular member. The wire isolation member includes an isolation plate unit delimiting a wire channel. The wire channel is located in the lateral slot. The isolation plate unit includes a stopper plate which is located in the lateral slot but does not come into a space delimited by the inner periphery of the tubular member.

摘要： A ceiling fan motor includes a sleeve, a stator unit fixed around the sleeve, a rotor unit rotatably mounted around the sleeve, and an axle detachably mounted to the sleeve. The axle can include an extending section and a suspension section. The extending section extends through and is coupled to the sleeve. The suspension section is exposed outside of the sleeve. The extending section can be contiguous to the suspension section. An outer diameter of the axle at the extending section can be smaller than an outer diameter at the suspension section to form a shoulder. An end of the sleeve can abut the shoulder.

摘要： An inner-rotor type motor includes an iron core having a magnetic yoke portion and a plurality of magnetic pole portions. The magnetic yoke portion includes an assembly hole through which a shaft extends. A plurality of magnetic pole portions is arranged around the magnetic yoke portion. The iron core includes a plurality of receiving grooves. Each receiving groove is formed between two adjacent magnetic pole portions. The permanent magnets are received in the receiving grooves. At least one abutting member is coupled with an outer periphery of the shaft and includes a radial extension portion having a guiding surface. The guiding surface abuts against at least one of permanent magnets. The iron core, the permanent magnets, and the at least one abutting member of the rotor are received in a compartment of the stator. The shaft of the rotor is rotatably coupled to the stator.

摘要： A motor of a ceiling fan includes a support unit, a rotor unit, a first bearing, a supporting bearing and a stator unit. The support unit has a shaft. The rotor unit has a rotational connecting member. The rotational connecting member includes a central hole through which the shaft extends, as well as an inner flange extending inwardly of the central hole. The first bearing includes an inner race fit around the shaft and an outer race connected to an inner periphery of the rotational connecting member. The inner and outer races are spaced from each other in a radial direction perpendicular to the shaft. The supporting bearing includes a fixed race fit around the shaft and a rotational race abutting with the inner flange. The fixed race and the rotational race are spaced from each other in an axial direction. The stator unit is connected to the support unit.

摘要： A ceiling fan motor with a reduced axial height includes a stator, a rotor and a light-emitting module. The stator includes an iron core and a shaft. The iron core forms an assembly opening at a central portion thereof. The rotor is rotatably coupled with an outer periphery of the shaft and includes a housing. The light-emitting module is at least partially arranged between the iron core and the shaft, or is arranged between the iron core and the housing of the rotor, along a radial direction perpendicular to the shaft.

摘要： An external rotor motor includes: a shaft, an insulator and a core. The insulator is coupled with an outer peripheral surface of the shaft, the core is arranged on an outer periphery of the insulator, and the insulator is formed between the shaft and the core, so that no electrically conductive route can be formed between the core and the shaft. A rotor has a housing rotatably coupling with the shaft, with an inner peripheral wall of the housing having a permanent magnet module.
