Brushless motor of low-loss snow remover Technical Field The utility model belongs to the technical field of brushless motors, and particularly relates to a brushless motor of a low-loss snow remover. Background The snow remover motor mostly adopts a brush direct current motor or a common alternating current induction motor as a power source. Although these conventional motors can meet basic driving requirements, they have problems in practical applications, particularly in terms of high load, long-term operation, and poor environmental suitability. The traditional brush motor has the advantages that because of physical contact between the brushes and the commutator, larger friction loss and spark can be generated in the operation process, the motor efficiency is reduced, the brushes are easy to wear, the service life is shortened, and the maintenance frequency and cost are increased. In addition, because snow removal operations typically occur in complex environments where low temperatures, moisture, and even ice and snow are mixed, brush systems are extremely vulnerable to moisture or freezing, resulting in difficult starting or unstable operation. The traditional motor has simpler heat dissipation design and mainly depends on a natural heat dissipation or passive air cooling mode. For example, cooling is performed only by means of the heat dissipation ribs on the surface of the shell and a small number of ventilation openings, heat accumulation generated by the snow remover under high-strength continuous operation cannot be effectively prevented, the temperature rise of the motor is too high, the output performance and reliability of the motor are affected, and even overheat burning of the motor is caused when the temperature rise is severe.
