Repair or Replace
Our policy: at least two proposals
Our policy is to give you at least two proposals with relative advantages of the 
repair or replacement products outlined with completion dates, for you to 
decide the economics
Your part is in evaluating the cost of lost production, and the 
loss of goodwill through late delivery
With our experience in repairing or replacing, a few minutes 
invested will always  shed some light on the likely economics, 
and time involved .

 ISO metric Standard Electric Motors
90% of  the motors in use in industry are ISO standard motors
 . Which means that many different brands of motor will fit in 
the place of each other and perform in a similar way
This  ISO  standard motor is a Brook Crompton W series 
electric motor which is very popular because of the quality, 
efficiency, and the ability to mount the feet in any one of three 
positions so that the terminal box can be positioned more 
conveniently.

Special Motors
ISO standard  motors are  available to suit the following 
applications: 
Flammable gases (EXD
Explosive dust (DIP)
Corrosive chemicals,( aluminium, cast iron or stainless , or  
epoxy finish )
Wet environments, ( IP56 to IP67 hose proof to submersible)
 Hot environments to  (250 deg C smoke spill duty) 
Cold environments  to -40 degC
Frequently we take an iso standard motor, and modify the 
shaft and flange s and mounting to  make them suitable for 
your special applications. This one is for a cryogenic freezer, 
has low temperature bearings, and an extended shaft

Rewind and Repair
Common examples of motors we routinely rewind or repair 
are ac servo motors, dc servo motors, AC 3 phase induction 
motors, AC three phase variable speed, Schrage motors, 
forklift drive motors, fork lift pump motors. Brake motors, 
magnet coils, solenoid coils Special motors of every kind 
          
 
 
Rewind Efficiency
 
The Electrical Apparatus Service Associations carried out 
extensive testing on rewound electric motors over an eight 
year period. They found that when the process is correctly 
adhered to there is no deterioration in motor performance or
 life.

machine spindle power supply.
Disassembly, clean and check all parts, rewind the rotating 
field, fit new brushes, and bearings, metalspray machine the 
endshield bearing housing
Assembly and test on full resistive load
Rotating Winding guaranteed for 3 years, 
Mechanical aspects guaranteed for 12 months 
Motor stator surge tested to find weaknesses not yet apparent 
at the working voltage, and so guarantee the winding for 12 
months

Typical work example
Bull 220kW 1725 rpm 360v DC motor 
Disassembly, clean and check all parts Motor cooling had 
been obstructed, overheated the motor , and melted the solder.
 
Rewind the armature. steam clean, oven dry, and varnish the 
stator. Reassembly, check interpole relationship, series winding 
polarity, and Brush neutral axis. Test No Load. Fit new 
bearings to circulating fan motor , surge test winding , 
guarantee the winding for 12 months, test on load. Reinstall, 
with 90 degree microtherm in cooling air outlet and commission.

Extra ordinary Work we have carried out
Parvex Servo Motor,280/37Amps,2400 Rpm ,
Mod-LC640TFR0514,
Faulty encoder position, another company had serviced this 
motor, and did not record accurately the encoder position on 
the shaft. Have spare electronic drives coupled to act as power
 supply with encoder feedback. Test encoder, and by elimination 
find encoder position. Make up a test rig, and instructions so 
that the test can be repeated at any future date easily.

Extra ordinary Work we have carried out 
75 kW 985 RPM Brook motor.
 Dough mixer drive  for Quality Bakers Auckland
Taking high amps on load, and tripping motor control. 
Call out to site, check current on load., found to be excessive
Fit replacement other brand motor, and test on load,
kW consumed similar, but peak amps on the replacement 
motor were less Does not trip the machine control
 
Test motor on no load in workshop, all results within Expected 
guidelines Disassembly, clean and check all parts, including 
special rotor and stator lamination testing. Found no fault.
Assemble and test motor on no load.
Transport motor to testing facility at ABB , 
Carry out full load testing , all results perfectly normal.
Mount this same motor back onto a second machine , different 
only in the direction of rotation and the dough mixer arm design.
And test, all results normal.
Conclusion The design of the dough mixer hooks are different 
enough
To add 20% in kW consumed
Our thanks to  ABB for their help especially to Peter.
Our recommendation was to run the one hook slightly slower 
than the other. and so consume less kW.

Challenging sometimes , Sometimes Easy
 
2 kW 1400 rpm special Bean splitting machine
Motor was burnt out due to overload when we had it dropped 
off to us for reconditioning.
 We repaired the motor shaft, and drive end housing, coated 
the housings in a two pot food grade epoxy coating
Rewound the stator, assembled and tested no load.
Within a couple of hours  our customer called us  indicating 
that smoke eased out occasionally.
We promptly looked into it and found that the lack of water 
flow  over the beans as they were split, caused them to stick 
in the discharge chute, and so clog the machine., and overload it.
Our solution was to fit correct current protection equipment 
on the motor supply for him, and recommend more water 
flow.
 
Conclusion: We are experts in our own products, but not in the 
processes or products our customers use. We need to work 
together to solve these technical hiccups.
