Abstract

The invention belongs to the field of motor cooling, and discloses a fan driving motor with a self-suction cooling function. The fan driving motor comprises a driving motor, a motor shell and a cooling air duct; one end of the cooling air duct is connected with the motor shell, and the other end is connected with an air inlet channel of the fan; a plurality of first ventilation holes and a plurality of second ventilation holes are formed in the motor shell, and the first ventilation holes are located in an area where the motor shell is connected with the cooling air duct; the driving motor ispositioned in the motor shell; and in the use state, the interior of the cooling air duct communicates with the interior of the air inlet channel of the fan. The interior of the cooling air duct is communicated with the interior of the air inlet channel of the fan and the interior of the motor shell, self-suction force is generated through negative pressure in the air inlet channel of the primaryfan, normal-temperature air is sucked from the atmosphere and flows through the interior of the motor shell, and the cooling capacity of the draught fan driving motor is enhanced in a forced ventilation mode.

Description

technical field [0001] The invention belongs to the field of motor cooling, and relates to a fan driving motor with self-suction cooling function. Background technique [0002] The three major fans of coal-fired power plants are composed of induced draft fans, supply fans and primary fans. The three major fans play a vital role in coal-fired power plants, responsible for sending air into the boiler, blowing coal powder and extracting flue gas. Maintain normal pressure and fuel in the furnace. The total power consumption rate of the driving motors of the three major fans accounts for about 2% of the power consumption rate of the factory. The safe and efficient operation of power plants plays a decisive role. [0003] At present, due to problems such as long-term uninterrupted operation and insufficient cooling capacity of the motor cooling fan, the fan-driven motor is overheated in summer all the year round and causes an over-temperature alarm, which seriously restricts the...
