Investment in Another CEMB Balancing Machine

We are proud to announce we have recently invested in another CEMB balancing machine. This is a smaller balancing machine, in comparison to our ZB2000. Investing in this equipment will allow us to balance smaller rotors easily and more accurately.

The ZB20/TCN/GV CEMB balancing machine implemented in our Electro-mechanical workshop has the capability to re-balance rotors up to 20KG. Built to provide precision and outstanding balancing capabilities, this machinery asset can feel any vibration within the rotor, due to being compact. This allows Neutronic to provide re-balancing to all small-sized motors.

What Machinery Assets Can be Rebalanced?

Rotors within a motor can be rebalanced on this machine. As part of the Electro-Mechanical repair Neutronic service, we rebalance every motor repair which is sent to our workshop. We understand this is a critical part of the repair to prolong the longevity of the motor, and minimise the need for replacements.

Benefits of Rebalancing Rotors

There are many benefits to why rebalancing rotors is important and a critical part of the repair, as stated below:

1) Reduction in Noise and Vibration. Noise and vibrations are both signs of a fault within machinery. Vibration within a rotor can be generated from loose connections, misalignment or internal damage. It is crucial for an engineer to take a look if your motor is vibration or making a noise.

2) Increase Reliability. If a motor is regularly balanced, this can improve the reliability of the asset, and unexpected breakdowns are less likely. It helps reduce long-term internal damage.

3) Improved Efficiency. Bearings and internal components will become damaged, if weight is uneven on a motors shaft. A correctly balanced motor allows the load to be evenly distributed and run efficiently.

4) Reduction in Maintenance Costs. If a motor is regularly re-balanced, it is likely to experience fewer mechanical breakdowns and will require less maintenance cost.

At Neutronic, we understand Reliability, Efficiency and Time is important to all of our customers which is why we quote re-balancing as part of each repair. This will allow you to have confidence that your machinery asset is correctly aligned it machining at maximum efficiency and low likelihood of unexpected breakdowns.

Choosing Your Electric Motor Repair Partner

Estimated reading time: 3 minutes

Table of contents

Not all motor repair facilities are equal, in fact the difference between a motor repair company and a quality motor repair provider could mean a huge difference for the longevity and efficiency of your repaired motor.

Unfortunately, the industry has no legislation to enforce the quality of the repairs that are carried out, so it falls to the person in need of the repair to do their due diligence, and ensure that they are procuring a high level of quality when choosing a repairer.

Repairers vary from independent 1 man operations working from tiny premises, to multinational businesses operating in various places around the globe. So when choosing your repairer, does big mean better? And does being affiliated with a trade body such as the AEMT guarantee a high standard of repair? The answer is no to both of those questions.

Motor being repaired in the Neutronic Technologies Workshop

When choosing your repairer, you need to ensure they have the appropriate equipment to carry out the repair properly and if the repairer has multiple sites. Make sure they have the equipment needed at the branch you are using. You would be amazed at how many companies I have come across over the years who are poorly equipped or even lack basic essential repair equipment.

What to ask your Electric Motor repairer to demonstrate?

Surge Tester:- Without a surge tester the repairer has no real way of performing electrical tests on the stator. A multi-meter and megger test is simply not capable of testing electric motors sufficiently. In our repair shop we use the Electrom Instruments iTIG III Winding analyser.

Pyrolysis Oven:- One of the major processes of rewinding a motor is to remove the old windings, varnish and insulation. It’s not an easy process unless you have one of these Ovens which you must not mistake for a curing oven, they are very different. It’s surprising how many rewind shops don’t have this equipment but without it you cannot guarantee the ongoing efficiency of the motor after the repair.

Dynamic Balancing:- Another large and expensive piece of repair equipment that is essential to a high quality repair. The balancing machine ensures the rotor assembly is finely tuned and balanced for all speeds of rotation. Remember a slight imbalance on a rotor can quickly degrade bearing life and cause damage to other areas of the machine the motor is connected to.

There are lots of other pieces of equipment that we use in the repair process such as sand blasters, wash tanks, curing ovens, rotor removal equipment, bearing heaters, cranes, mechanical measurement devices and countless other tools, but in my opinion the 3 listed above are by far the most important for any rewind shop to effect a quality and reliable repair.
