How our Magnet Charging  Facility can help you

Our Policy is to check the flux density of permanent magnets before proposing a 

rewind of the armature or stator.

Saves time and money in rewinding a motor which will never perform.

Permanent magnet electric motors are very common and magnets become weak through 

power supply faults, winding faults, overload, or shock.

We have the necessary equipment to measure the flux density of permanent magnets, 

before a repair, and so avoid the time, cost and risk of rewinding a motor with weak 

magnets.

Motor and transformer windings, Samatic 12/3 tester

Your motor and transformer windings are tested on site up with 

this extremely sensitive  equipment It detects weakness in the insulation, not yet 

aparent at the working voltage. This enables us to provide a guarantee on the 

materials and workmanship I the winding for 12 months.

Surge testing

This equipment puts out an international standard pulse When connected to a   

winding, measures the reflections, and represents this on a screen  graphically with  

a numerical summary.  A second and third reading is taken, and comparisons made. 

Where significant variances occur,  a likely fault exists.

Polarity Index Test

Is usually carried out on motors over 75 kW, it measures the electrical resilience of the 

insulation, over a 10 minute period the voltage is held at a certain  level, end the leakage 

current measured.

(low leakage at the end if the test is good, when compared with the beginning)

Rotor testing without disassembly

The Samatic Surge tester basically measures inductance,  using it in a slightly different 

mode measures the change in inductance due to broken rotor bars,. 

Worn Bearing housings

This equipment has in fact found worn housings. The inductance changed so 

significantly due to the air gap inside the motor closing, as the slightly eccentric rotor 

turned

Power supplies

Laptop oscilloscope

We can test power supplies up to 2000 amp ac or dc for waveform of current and 

voltage in real time .

Datalogger

We can log any parameter of voltage current resistance, temperature for an indefinite 

period, and also we can record any of these parameters before and or after a selected 

event .

This is especially useful in finding the source of intermittent problems 

Transient analysis

Equipment reliability is affected by transient waveforms in the power supply

We are able to measure, and analyse , and trace the source of  the offending transient. 

The equipment uses FFT analysis , represented graphically

Ultraprobe 2000 

Used to listen to bearings, in the inaudible ultrasonic frequencies, this is where the sounds of wear 

in bearings is initiated.

A little experience on the operators part enables discrimination of "normal to worn" sounds.

top

Vibration analysis

Machine condition

Commtest 3000 used to record a machine signature.

This is the spectral representation of all vibrations in the machine. This information is 

used to monitor machines for wear.

As it is very sensitive to changes, it can detect machine wear in the very early stages, 

e.g. loosenes of mounting bolts, loose drive belts, worn couplings, worn bearings,

When the bearing  size and brand is known it is  very easy to tell  which part of the 

bearing is worn.

Your Motor efficiency  is our concern)

kW Clampmeter

kW taken measured instantaneously, or averaged over time.

Downloaded to a laptop, for reporting.

Maximum, or minimum also give indication of load requirement

This is especially useful when deciding suitability for the powerboss intelligent soft starter.

This equipment measures kW consumed on one phase, as well as power factor, KVA, 

Amps, Votts. With True RMS values

Magnetic Flux Measurement

Many motors today have permanent magnets inside them.

When faults occur in the power supply, or in the motor winding, it can lead to damage in

 the permanent magnet. 

DC motors generally have magnets in the stator, of two common varieties, and 3 other 

less common types, thye each have normal flux densities different, need to be identified, 

and measured before other repairs take place

AC servo motors more common today, have rotating permanent magnets.

It is vital to check the flux density of this befor  the stator rewind, which is very easy

 to carry out. We have developed several ways to recharge magnet on rotors and stators.
