Repair of 400V electric motors
We undertake full maintenance of these machines and repair of electrical and
mechanical faults without any performance limitation.
We are taking apart the motors with the newest technology that available our factory, just like hydraulic pulling machine, and after that we are begin to clean the parts with solvent and water-based materials too.
The drying, happening in a industrial furnace with fully controlled by computer.
We work closely with our supplier and our customers to ensure the high
performance, and we using first of all SKF and FAG tpye bearing for the high performance too.
In every workflow we are chaking the tolerance of fit dimmensions, flatness, size tolerance, and alignment too. In the case of something wrong, we are looking for the problems parts and reapair it, at the workflow that we found. We can made heat treatment and CNC works too, inmadiatly at our factory, if the case is
requires. Then we ended the work, we checking out the motors, like – rotor balance, –
electrical test, – test flights
We useing „F”, „H”, and „C” type of insulating material for the stator- and rotor.
According to the customers needs the Viceroy Ltd. undertake rewind for other speed or other voltage too.
Every time, before we starting the winding, we perform an inspection on the core. We cheking the iron short circuit, and the physical parameters. ISOVOLTA, KREMPEL, ISOLA the most popular material what we our factory using. There is an opportunity using other material, if the customer request it. For the motors impregnation, and enamelling the we are using Dolphin resin.
In this case of the motor needs we changing the carbon brushes, we regulate the slip ring, and seting up the brush holding pressure. The end of the repairing the motors, it get corrosion protection, then, primer and the last paint according to the customers wishes.
During the internal painting, the elements exposed to corrosion, are get the right chemical process, and the necessary other thing the engine requires. We make the painting of the engine, in a painters cabin, what working with flowing air warm, thanks to these processes it can be dry in few hour.
We can provide automatic lubricator, bearing temperature, status, and vibration
sensor and other sensor for the requiest our costumers.
Repair of 6kV electric motors
The elctrical failure, somethimes can be repairable inmediatly, just like the insulation repair, or some parts exchange, but the most of times need rewinding. We make the insulation for specially designed wire, for the costumer requested with the current latest technology all with a special gruop of machines.
We use qualified raw materials, with has very well electrical properties, because their use many times lowest then the similar machines. Compared to insulating materials used in machines operating in the lower voltage range.
We pay a lot of attention, for the good quality of coil elements, from the insulation to the impregnation.
For making coil elements used by the ISOVOLTA materials, and the „Resin-Rich” technology.
The Viceroy has undertake without power limit maintenance of devices, bearing, mechanical components – shaft, shields, terminal housing, bushings, etc – improves.
We can make simple high voltaga coils, and full high voltaga coils with deadline. According to the customers, it has oportunity to undertake maintence on the costumer site.
Repair of explosion proof motors
The explosion proof motors has got more attention, all the electric side, then the mechanik side to. For the repairing, only useing for qualified parts and materials.
Only that person can made the repairing who has owner a special certification – MSZ
EN 50014 – 50020) – because in the all workflow can measure, the repair result, from
the gaps, tolerances, to the vibration – about the engine making. After that he must
made offical statement, and a certufucates that tha EXP motors is safety.
