Abstract

The invention discloses a motor with an immersion type liquid cooling stator armature. The motor with an immersion type liquid cooling stator armature includes an end cap for a non-driving end, an end cap for a driving end, a rotor, a stator, a non-driving end bearing and a driving end bearing, wherein the stator includes a seal cylinder, a support, a seal-end cap for a non leading-out end, a seal-end cap for a leading-out end, and a stator armature; an independent seal cavity is formed through enclosing of the seal cylinder, the support, the seal-end cap for the non leading-out end, the seal-end cap for the non leading-out end and the stator armature; a liquid outlet seal cavity and a liquid inlet seal cavity are respectively connected with a liquid outlet end pipeline and a liquid inlet end pipeline; the stator armature includes a tooth support and a plurality of iron core punching sheets; an opening groove is formed in each iron core punching sheet; in-groove pipes are arranged in each opening groove; a stator coil is arranged in a groove which is formed by the in-groove pipes; and the stator coil is swelled by a groove wedge. The motor with an immersion type liquid cooling stator armature starts with the motor topological structure and the stator cooling mode to optimize and arrange the cooling pipeline, and can effectively control temperature rise of the stator and improve the reliability of the motor so as to satisfy the requirement for high heat load, compact structure and high torque density of the motor.

Description

technical field [0001] The invention belongs to the field of motors, and in particular relates to a motor with immersed liquid-cooled stator armature. Ship propulsion motors or wind generators with high density requirements. Background technique [0002] In some applications, it is necessary to use motors with small size, high power density, light weight, safe and reliable operation, etc. Compared with conventional motors with the same capacity, the thermal load and torque density of the motor are greatly increased. As a result, the loss per unit volume of the motor and the operating temperature rise increase significantly. Therefore, it is necessary to optimize the design of the overall topology of the motor and the cooling system to effectively control the operating temperature rise of the motor while satisfying the electromagnetic performance of the motor. High torque density requirements, thereby reducing the volume and weight of the motor, improving the performance of...
