The selection principle of the machine

Modular technology advantages,together with its competitive price and the total life significantly reduce costs,will speed up direct drive technology in the design of the new machine application in many fields,such as metallurgy,packaging,printing,semiconductor and factory automation.Please see the following an example:a is trying to make the machine more than 150 pieces/minute packaging OEM production,they face the challenge of gear box on a key axis of flexible when they tried to raise production machinery interference is introduced.For another modular direct drive applications:a OEM service for tyre and automobile industry provide test/measuring equipment,the company found that use of direct drive technology improve the quality of the measurement and the reliability of the machine,its reason is to eliminate invalid stroke and other external effects by a belt and pulley system.Their original design USES a frameless direct drive motor,compared with the traditional solution,it has brought many benefits,but also the disadvantage of assembly and installation difficulties-in fact,the combination of the frameless motor and feedback device on the need to spend the whole day.As a result,the company turned to the modular direct drive technology,found that due to its simple installation,integration only spent about 30 minutes,is much save time and cost.In

addition,they are glad to see that compared with the frameless direct drive type,modular motor torque

density is higher.

Because of its unique design,modular DDR motor compared with the traditional mechanical drive servo motor,appear more competitive in price.Even if the initial cost of a little higher,but in the five years of use,the operation cost of this new technology is greatly less than traditional systems.Today's most servo applications use the traditional servo motor system with mechanical transmission.The initial cost of attractive traditional system,and performance has been verified in various applications,these applications include:electronics assembly,packaging,aerospace and defence.However,people often don't notice this kind of system in the aspect of design and integration of extra spending costs,these additional spending for pulley,gearbox and belt and so on need to add the mechanical components.These parts in the whole machine life wear constantly,it also increases the total cost of life.Positioning error and tuning difficulty is common problem in these systems,they are caused by the transmission of the flexible and invalid clearance.Belt and pulley and transmission maintenance and replacement of the easily worn parts are need to pay a high price:first of all,users have to more parts inventory management; Secondly these additional parts caused by system failure increases system unplanned downtime,making machine production fell.Role can directly produce driving the rotation of the motor is essentially a large torque of permanent magnet motor,it is directly connected to the load.This design eliminates all mechanical transmission parts such as gears,belts,pulleys and shafts.

Direct drive rotary system brought many benefits for designers and users.Because of a mechanical transmission require regular maintenance and frequently cause unplanned downtime,therefore,direct drive rotary motor technology fundamentally improve the reliability of the machine,reduce maintenance time and costs.By eliminating the mechanical transmission of flexible,direct drive design to avoid the trouble of motor and load inertia matching,at the same time,the positioning precision can also improve the speed and 50 times.Direct drive motor also bring another benefit:water pump motor acoustic noise reduction as much as 20 db.Closed and open frame type direct drive rotary Y series motor,in a variety of applications has replaced the traditional,servo motor system with mechanical transmission.And now a new,called modular (cartridge) direct drive rotary (DDR) technology of DDR will open frame type direct drive motor in terms of performance advantages and whole framework combines the advantages of convenient installation,its price is much lower than the traditional direct drive technology.DDR motor for semiconductor process equipment is an ideal solution,because the motor is directly connected to the driven load,eliminates the traditional servo motor system usually must use the belt,pulley and gear box.The reduction in the number of parts makes the machine's overall size is reduced,the production management personnel can put more in a process of the compartment,high added value of the process equipment.Elimination of mechanical transmission parts bring a no maintenance system,and the system work more quiet.

The motor www.facebook.com/guohong.trading is nature customised,therefore more expensive,need

for weeks,even months for the design and integration time.In addition,once the system failure,motor or feedback device to take out the replacement process is extremely complex.Frameless DDR motor lamination technology,therefore,is not suitable for each kind of application,it is the most widely used in airborne and ground vehicles,such as night vision equipment,radar system and weapon system aimed at control,as well as those on the size,weight,and/or performance has a higher requirement of high-end industrial applications,such as robots or precision grinding machine.(closed) direct drive rotary motor with shell,is the aim the rotor,stator and before they go out to complete the feedback device integrated into a shell with a precision bearing,is a complete solution.Enclosed for direct drive rotary motor load can ride across on the motor bearing applications is very ideal.For motors have been used for bearings,users need to put the motor

connected to the load,or three or more complete alignment of bearing,it will be a hard and time- consuming work.Therefore,enclosed DDR motor is generally used in dividing and application rate turntable.Modular (Cartridge) DDR motor is a new kind of direct drive solutions,its structure includes a unique without bearing shell and shell in the integration of the rotor,stator,and before delivery to complete the alignment of the high resolution feedback devices.

Cylindrical DDR technology application to eliminate the mechanical transmission parts,both retained all the advantages of direct drive,and avoids the traditional closed or frameless DDR solution complex and expensive

shortcomings.Modular direct drive rotary motor using novel compression coupling device to the rotor and shaft together,and provided with a unique design of clip so as to realize the "out-of-the-box",it takes less than 30 minutes.Through the shaft up installation modular direct drive rotary motor,eliminates the mechanical flexible,wholesalemotor.blogspot.com makes the OEM can increase the output of the machine to 180 pieces per minute.Besides increasing yield,the OEM also realized the following benefits:zero maintenance workload,the improvement of reliability and acoustic noise reduction.
