摘要： A motor assembly and a motor rotor are provided. The motor rotor includes a mandrel, a carrier, a plurality of iron cores, and a plurality of magnets. The outer edge of the carrier has a plurality of protrusions that are spaced apart from each other. A setting groove is formed between any two of the protrusions adjacent to each other. The iron cores are respectively fixed on the setting grooves. Each of the iron cores does not contact each other, so that an accommodating space is formed between any two of the iron cores adjacent to each other. One of two ends of each of the iron cores has a convex portion, so that each of the iron cores is connected to the corresponding setting groove through the convex portion thereof. The magnets are respectively disposed in the accommodating spaces.

摘要： A closed-cycle heat dissipation structure of a motor is provided. The motor includes a shell. The closed-cycle heat dissipation structure includes a plurality of thermal conduction members and a heat dissipation device. Each of the thermal conduction members defines two ends thereof as a heat absorbing end and a cooling end. The heat absorbing end of each of the thermal conduction members is connected to a stator of the motor, and the cooling end of each of the thermal conduction members penetrates the shell of the motor and extends out of the shell. The heat dissipation device is disposed outside of the shell of the motor, and the cooling end of each of the thermal conduction members is connected to the heat dissipation device.

摘要： A motor, into which air in an external environment is blocked from flowing, is provided. The motor includes a motor main body, a gas collection element and a protection component. The motor main body has a chamber. The gas collection element is disposed outside the motor main body and has a gas collection space. The gas collection space is only communicated with the chamber and allows gas to be exchanged between the gas collection space and the chamber. The protection component is disposed outside of the motor main body and used to protect the gas collection element.
