ANY IDEA HOW THIS WORKS ON A FUEL PUMP ENVIRONMENT.THIS MAY BE VERY USEFUL SINCE THIS WORKS IN PARLLEL TO THE BRUSH AND NO CURRENT WILL FLOW THRU THE SUPPESSION DEVICE.
EXPENSIVE SILICON STEELS ARE USED IN SMALL TRANSFORMERS (UPTO 500VA FOR UPS)WITH NO LOAD LOSS GOING UPTO 12WATTS.(M6,50RM600 ANNEALED/UN ANNEALED ETC)
ONLY GRADES OF STEEL IS CHANGED TO GET THE REQUIRED CORE LOSS .IS THERE ANY OTHER ONGOING IN EXPENSIVE DESIGN SOLUTION TO MINIMIZE THE NO LOAD...
I HAVE A SPECIFIC QUESTION ON IMPACT OF BRUSH MATERIAL,BRUSH PROFILE ,SHAPE ON THE RFI SUPPRESSION PROPERTIES IN PMDC MOTOR.ANY TECHNICAL LEAD WILL BE USEFUL.
(EXPERTS FROM "CARBONE,MORGANITE,HAFFMAN "CAN THROW SOME LIGHT ON THIS??? IF IT IS NOT SECRET
I would like to understand the impact of brush material,brush dimension and any other profile or shape that has an impact on the RFI suppression in permanent magnet dc motors.Any technical lead will be useful.
WE ARE IN THE PROCESS OF MAKING A MAGNETIZER FOR MAGNETIZING ARC TYPE BONDED NDFEB MAGNETS.BUT WE COULD REACH ONLY 80%FLUX LEVEL IRRESPECTIVE OF APPLYING MAXIMUM MAGNETIZATION FORCE.IS THERE ANY CRITERIA LIKE SHAPE OR FIXTURE CONSIDERATION THAT AFFECT THE FLUX VALUE OR LIMITING THE SATURATION...

CAN ANYBODY HELP TO DETERMINE THE FOLLOWING MORE PRECISELY:
HAVE A SHAFT OF 4 MM DIAMETER
ASEMBLING A COLLAR ON SHAFT WITH TWO DIFFERENT MATERIALS
BRASS AND STEEL
THE THICKNESS OF COLLAR IS 3MM
THE INTERFERENCE MAXIMUM BETWEEN BRASS COLLAR AND SHAFT IS 20MICRON
THE INTERFERENE MAXIMUM...
FOR BETTER POSITIONAL ACCURACY WE WOULD LIKE TO REPLACE OUR 1 TON PNEMATIC PRESS WITH A SERVO MOTOR.CAN ANY BODY RECOMMEND A SUITABLE SPEC /ECONOMIC SOURCE FOR SUCH SERVO MOTOR
CAN ANYBODY E MAIL THE SPEC DETAILS REGARDING QUALIFICATION TESTS FOR FLAT COMMUTATOR for FUEL PUMP APPLICATION AS PER UL FILE 1004
URGENT PLEASE

has anybody come across cost effective laser welding machines from fareast?we are using it to weld some washers in brackets and we need a new machine for welding a bracket as well.currently we get it from miyachi japan which is too expensive
these motors are used as drain pump in washing machines/dish washer applications
widely.have seen basically two types of strating mechanism-one system has got double winding and the other one was a patented mecahnical system in which a small amount of jerk is created which helps in rotation.can...
we are using bonded ndfeb magnets for our dc motors.but we could not
introduce this motor to several automotive application because of high cogging torque.
can anybody share their experience on reduction of cogging torque using bonded ndfeb magnets
WE HAVE TO DECIDE ON A SUITABLE CLEANING SYSTEM TO REMOVE CONTAMINANTS OF PARTS THAT ARE ASSEMBLED ONTO ARMATURE AND BRUSH BOX ASSEMBLY WHICH CONSISTS OF MATERIAL LIKE PPS,SS,COPPER,STEEL.CAN ANYBODY RECOMMEND A SUITABLE MEDIA OTHER THAN TRI CHLORO ETHYLENE WHICH HAS BEEN BANNED NOW TO HAVE...
WE HAVE TO CONTROL PPI(540 TO 800)AS WELL Rz 8 TO 10.FOR TURNING OF COMMUTATOR (COPPER).THE PROBLEM IS TO ACHIEVE THIS SPEC WE HAVE TO REALLY GET A ZERO RADIUS TOOL OF 115 DEG.WHICH WE FIND VERY DIFFICULT TO GET.IS THERE ANY OTHER METHOD BY WHICH WE CAN GET THE ABOVE PERFORMANCE .ANYBODY HAS...
CAN ANYBODY EXPLAIN THE REAL STATUS OF THE DEVELOPMENT/AVAILABILITY OF ULTRASONIC MOTORSS.WILL IT REALLY REPLACE THE PERMANENT MAGNET MOTORS IN FUTURE.WOULD LIKE TO GET SOME GOOD INFO ON SUCH MOTORS
WE HAVE A DISPENSER FOR LOCTITE.BUT IN AUTO MODE NO DETECTION IS POSSIBLE WHETHER THE DISPENSER DELIVER LOCTITE OR NOT.THE QUANTITY FOR THE CYCLE IS JUST ONE DROP EVERY 1 MINUTE AND DIFFICULT TO USE CONVENTIONAL OPTO SENSOR SINCE IT IS INTERMIDIATE.IS THERE ANY SENSOR WHICH SENSES THE PRESNCE OF...
IT IS NORMAL TO HAVE VERY TIGHT SPEC FOR BALANCING VALUES (16MICRON DYNAMIC AND 8 MICRON STATIC FOR ARMATURES OF SIZE 28MM)BUT THIS SPEC RESULTS IN OVER 2%REJECTION FOR VIBRATION.THE REJECTION OF MOTOR FOR VIBRATION IS VERY LESS IF THE SPEC IS HALVED BUT RESULTING IN VERY POOR PRODUCTIVITY.ANY...
