Self-ventilation motor highly efficient in cooling and heat dissipation

Abstract

The invention relates to a traction motor for locomotives, in particular to a self-ventilating motor with high-efficiency cooling and heat dissipation. High-efficiency cooling and heat-dissipating self-ventilated motor, including rotor, base, and end cover, wherein the rotor includes a rotating shaft and a centrifugal fan, the base includes a stator core and a casing, and the casing is provided with an outer circular air inlet and an outer circular air outlet. There is an air inlet on the cover, the stator core is fixed on the casing through ribs, there is a ventilation space between the stator core and the inner wall of the casing, and there is an axial ventilation hole on the rotating shaft, thus forming four air passage structures. The heat source stator winding, stator core, bearing and rotor core in the motor with the unique cooling air path structure of the present invention are well cooled, and the generated heat can be well taken away. The motor with the structure of the invention has the characteristics of excellent cooling and heat dissipation capacity, and is especially suitable for the performance requirements of the traction motor by vehicle users.

Description

technical field [0001] The invention relates to a traction motor for locomotives, in particular to a self-ventilating motor with high-efficiency cooling and heat dissipation. Background technique [0002] The motor-driven vehicle is a new energy green vehicle that has emerged in recent years. It uses electric energy as the power source and drives the vehicle through a power traction system composed of a controller and a traction motor. Compared with traditional fuel vehicles, it has the advantages of zero emission, no pollution, energy saving, consumption reduction, and environmental protection. The core of the motor-driven vehicle is the power drive system, including the controller and the traction motor. The particularity of the vehicle's operating mode, operating environment, and technical performance determines that there are special requirements for the traction motor, which requires frequent start and stop of the motor, intermittent work, and low-speed torque. It has ...
