Motor core technology into electric tool development main bottleneck

Learned, the core technologies of electric tools have four projects, motor manufacturing, precision alum parts processing, emc, injection. And the most key of index to test power tools enterprise is the technical system integration, which makes the noise and vibration lower in the corresponding fast speed.
Motor is professional electric tool heart that motor manufacturing technology show manufacturer's core technology level.Electric tool motor smaller volume, high speed and more power output of motor bearing, rotor,gear ,accuracy requirement is high.
Because professional electric tool to use in building roads, metal processing, wood processing aspects, ask product is small in order to carry.General motor speed should reach 18,000 turn/minutes, and professional electric tool speed requirements to 30,000-40,000 turn/minutes, far higher than general motors.
High speed, small volume, the larger the output power of motor rotor gears, bearings and the processing manufacture precision, wearability, rigid raised very tall requirement, so for making gears of raw materials, processing and assembling process raised very tall requirement.
In addition, high-end power tools to the motor temperature requirement is high. Because professional electric tools need in big load, state of uncertainty, motor overloaded work under high-speed operation will generate high quantity of heat, such as the core component of motor stator and rotor etc to a higher temperature performance.
This will inevitably ask its purchasing higher quality of motor, prospectuses existing suppliers is often very difficult to achieve high electric tools motor product technical requirements. In front of the power tools, it is necessary to introduce more professional motor suppliers, and high-end motors purchasing also tend to be more than domestic brand high on 9 times of motor, some even more, manufacturing costs lead to its sale price and foreign brand yielding around words, open the high-end market will face many problems.
Professional electric tool system integration ability to meet the end user's demand as the essential starting point, not just simple device assembly, but to integrate the most suitable user needs products and technology, involving integrated design, manufacture, commissioning and application support need through structured integrated wiring system and control technology, each separate parts, including motor, gear, transmission parts, work top parts set to the interrelated, unity and coordinate system.
Professional electric tool system integration between the system needs to solve the interconnection and interoperability problems, such as motor and transmission parts system to solve the fit, driving system and working head the fit, electric tools parts and the shell and handles the conjunction.
These integrated need to face a variety of suppliers (e.g. electricity mechanism needs enamelled copper makes suppliers, JueYuanQi suppliers, XiGangPian suppliers), a variety of application system structure, this needs to solve all kinds of equipments, subsystem of the interface between, agreement, and application environment, organizational and personnel related problems.
Only through system integration technology, ability makes professional electric tool overload ability, use efficiency, noise and vibration reduction indicators meet different customers' requirement.
 Professional electric tool system integration is the core of the integrated design ability, by integrating the optimal design of motor and transmission system, work head, operation device layout scheme, and for different manufacturer product selection, collocation, so as to realize the professional electric tool that the system integration of goals to achieve: overall optimal performance, namely all components combined with a professional electric tool system is reasonable and efficient cost.
Because professional electric tool product has the product updating cycle is short, the more complex shape, mold piece and reliability requirements higher characteristic, development process and complex and precision, involving materials, manufacturing, process factors, the product shape of often need many design, testing, improvement.
Despite the CAD and rapid prototyping technology as support, but electric tool technical personnel still face some big challenge.
