What are some of the characteristics that need to be met by a good decelerating motor? First of all, it needs to be combined with international technical requirements, to have a high level of technology, in the space-saving, reliable and durable premise, to have a high overload capacity, the power needs to reach 90 kilowatts or more. Energy consumption must be low, performance must be good, efficiency to achieve more than ninety-five per cent, low vibration, low noise, energy-saving high-quality steel, steel cast iron box, gear surface after high-frequency heat treatment. After precision machining to ensure shaft parallelism and positioning accuracy, all of which constitute the gear reducer equipped with a variety of motors, forming a mechatronics engineering, fully guarantee the use of product quality characteristics.
