AI Technical Summary
The magnesium alloy housing of existing mid-drive motors is prone to electrochemical corrosion, and the motor bracket is easily deformed by the force of the screws, which affects the installation accuracy and increases the difficulty and cost of processing.
The connecting rods are wrapped with an isolation layer, and the motor bracket is indirectly connected through the first and second fixing parts to avoid direct contact. Non-metallic isolation materials, ceramic coatings, or zinc-nickel alloy coatings are used as the isolation layer. Combined with aluminum alloy bushings and a preset gap design, this prevents electrochemical corrosion and improves installation accuracy.
It effectively prevents electrochemical corrosion, extends the service life of motors, reduces maintenance costs, improves installation accuracy, simplifies processing procedures, reduces costs, and improves assembly efficiency.
