Problems solved by technology
This is because when most of the cooling air flow passes through the second air path, the flow through the air gap in the first air path drops significantly, so that the rotor cannot be effectively cooled

The invention discloses a stator and a motor comprising the same. The stator comprises a stator winding and a stator core. A baffling air duct is arranged in the stator core, wherein one end of the baffling air duct leads to a winding gap formed between adjacent stator windings, and the other end of the baffling air duct leads to an inner cavity of the stator. The stator also comprises a pluralityof radial ventilation grooves, wherein one end of each radial ventilation groove is communicated with an air gap and the winding gap, and the other end of each radial ventilation groove is communicated with the inner cavity of the stator. By combining the radial ventilation grooves and the baffling air duct, one part of cooling fluid flows through the air gap, the radial ventilation grooves, a cooling rotor and a cooling stator, and the other part of cooling fluid flows through the winding gap, the radial ventilation grooves, the baffling air duct and the cooling stator, so that the internalflow resistance of the motor is reduced, and the motor rotor is cooled. By reasonably designing the sizes, the number and the arrangement of the radial ventilation grooves and the baffling air ducts,the flow proportional relation of cooling air flowing through the air gaps and the winding gaps can be adjusted, and therefore, the optimal cooling effect is achieved.
Description
technical field [0001] The invention relates to a stator and a motor including the same. Background technique [0002] Large motors will generate a lot of loss during operation, causing the temperature of each component of the motor to rise. The temperature rise of these components must be effectively controlled to ensure the stable and normal operation of the motor. Among them, most of the losses occur in the stator winding, so that the temperature rise of the stator winding and the components connected to it is much higher than other components. Excessive winding temperature will accelerate the aging of winding insulation, even cause winding insulation failure, and also cause excessive deformation of mechanical structural parts. Therefore, the stator winding is a key component in motor cooling. How to reasonably design the cooling system and cooling structure to control the temperature of the stator winding within the limit is one of the main challenges in motor design, e...
