This steel motor housing features a lightweight precision design with an inner diameter of 120mm, height of 69.9mm, and a wall thickness of only 1.2mm, achieving extreme light weight while maintaining structural rigidity.
·The precision-machined end faces have a parallelism tolerance within 0.1mm, ensuring perfect fit with the end covers, effectively improving overall assembly accuracy and sealing reliability.
·Ventilation holes are designed on both ends, establishing an efficient axial air cooling channel that allows airflow to pass smoothly through the housing interior, directly cooling the stator and rotor assemblies, significantly reducing temperature rise, and greatly extending the motor's service life under continuous high-load conditions.
