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.
Faults exclusion is an important work of maintenance personnel,to eliminate the fault,must know the cause of the failure,more important is can theoretically analysis,solve the fault occurred,should have certain professional theory knowledge,to master the methods of troubleshooting.(a) gradual deduction:if there is a short circuit fault occurs,can be gradually removed part of the circuit to determine the scope of the fault and fault point.(2) adjust the parameter method:in some cases,failure,circuit components is not necessarily bad,line contact is also good,just because of some physical quantity adjustment may be inappropriate or run after a long time,likely due to external factors causing system parameter electrical motor changes or not automatic correction system value,resulting in system cannot work normally,at this time should be adjusted according to the actual circumstances of the equipment.
(3) the principle analysis:according to the principle diagram of the control system,by tracking that is associated with fault signals,the analysis judgment,find out the fault point,and find out the cause of permanent magnet generator the problem.Using this method requires maintenance personnel and unit of the whole system working principle of the circuit have a clear understanding.(11) comparison,analysis,judgement method:it is according to the working principle of the system for controlling the action program and the logical relationship between them,in combination with failure phenomenon,comparison,analysis,and judgment,and reduce the measurement and inspection link,and quickly judge fault range.Above several kinds of commonly used method,can be used alone,also can mix,met the actual electrical fault should be combined with the specific circumstances and flexible application.
Electrical fault phenomenon is varied,the same type of failure may have different failure phenomenon,no similar failure may be the same failure phenomenon www.facebook.com/dongfeng.motor of identity and diversity,complexity to malfunction.Fault phenomena,however,is to find the basic foundation of electrical failure,and is to find the starting point of electrical fault,so be careful observation of fault phenomenon analysis,find out the fault phenomenon in the main,the most typical aspects,find out the failure time,location,environment,etc.A lot of electrical failure,must rely on the professional theory knowledge to really understand have a good grasp of.Electrical maintenance personnel and other workers maintenance personnel in comparison,more theoretical and sometimes no theory to guide a lot of work,it's impossible to be so to have certain professional theoretical high efficiency electric motor knowledge.Maintenance personnel in order to better improve their ability to solve practical problems effectively in the practical work and maintenance level,should constantly strengthen their own professional theoretical knowledge learning and improve the level of operating skills,when electrical fault occurs,can accurately locate the fault,and troubleshoot electrical equipment can steadily run normally.
