Here at Beatson Fans & Motors Ltd, we offer a wide variety of repair services. Our fully comprehensive workshop, run by our highly skilled engineers, and backed up by 95 years of industry knowledge, means we can offer a service that is both reliable and competitive locally and nationally.
Our workshop facilities include Electric Motor Rewinds, Machining, Fabrication and Mechanical Repairs as well as all types of fan repairs as referred to on our Industrial Fan Repairs page.
An electric motor rewind is a term referred to the replacement of the coils (usually copper) which may have failed in an electric motor. The coils are ‘wound’ to a number of turns hence the term ‘rewind’.
A skilled rewinder can look at the failed windings and know how to replace those windings. Essentially copying what was already there with new wire and better insulation.
There are numerous ways to prolong the life of your electric motor… These are some of the most common faults we encounter with electric motors when they arrive at our works for repair or replacement, which may result in your motor being rewound.
An electric motor will get hot and start overheating for a number of reasons… The motor may be overloaded which will eventually cause the motor to stall and windings to get hot and cause them to burn.
There might be a phase-off (on a 3phase motor) which will cause the winding on the failed phase to burn out as it will struggle on two phases.
The insulation between the windings has broken down over time, thus causing a short circuit in the windings. When this happens, the motor often goes with a little ‘pop’ and a puff of smoke.
Electric motors have a cooling fan on the back of the motor which is covered by a fan cowl. As the impeller spins with the speed of the motor the cowl directs the air down the fins of the motor body to keep the motor cool.
If the holes in the fan cowl get blocked up, this will cause a problem as essential cooling can’t be maintained, again, this will cause your motor to overheat and potentially burn out.
Environment: Water & Dirt Ingress
Quite often industrial environments can be harsh! It’s important to make sure that you select the right motor for your environment. Most standard 3phase and many 1phase IEC motors are IP55 as standard, which is generally OK for industrial environments such as machine shops and factories.
Sometimes, however, if the environment is particularly harsh, such as on a ship or in a quarry, the IP rating must be uprated to IP65 or even 67. Thus protecting against dust and water ingress which would cause the motor to fail.
If you have a vibration on your electric motor, this could be for a number of reasons. All of which will invariably involve the bearings and sometimes the motor shaft.
If your motor has been running with the shaft out of alignment i.e. Your motor has a pulley on it which drives a fan and the belts have been set too tight, the tension will put extra load on the bearings causing them to fail, which will cause the rotor to drop and rub directly on the stator, which will result in a motor failure.
You may have a fan attached to your motor. If the fan is out of balance this will cause vibration which will transmit down the shaft and again destroy the bearings and potentially damage the shaft and the bearing housings. If the bearing housings are damaged, the best option may be what we call MIWANO – Mend It With A New One!
Following your initial inquiry, we offer a free local collection and delivery service for all customers in Sheffield and the surrounding area. Alternatively, you can drop it off at our workshop, or arrange for courier delivery.
Inspection and stripping
Once we have your motor in our workshop, our engineers will test the motor electrically and if necessary, strip it down to its component parts for a closer mechanical inspection. This process will help us decide on the best course of action to take.
Repairs, Rewinds, or Refurbishments
Once decided which course of action to take, be it a repair or a rewind or a new unit, we will quote our best price and delivery based on our decision.
Hopefully, a price for repair is agreed upon between BFM and our valued customer and we are able to proceed with the repair, rewind or replacement of the motor.
Once we are we have repaired or rewound the motor, we test our work electrically and mechanically on our purpose-built test bench, making sure there’s no mechanical vibration and that all phases are in balance.
If we are testing the entire machine, the motor is attached so we make sure that the entire machine is running satisfactorily and that all phases are balanced and running with their Full Load Current.
Clean and Respray
Whilst the motor is stripped down we make sure that all the component parts are cleaned appropriately.
Once the motor has been reassembled and tested again, we will re-paint the motor in our spray bay to make it look as good as new.
With your motor back in working condition, we offer free delivery to businesses within the Sheffield area. You can also pick it up from our workshop, or we can arrange for a courier to deliver it further afield.
Established in 1928, Beatson Fan & Motors is a fourth-generation, family-run business, with over 95 years in the electric motor trade. We work closely with our customers, offering free testing and quotations and guiding you through the rewinding and repair process.
