There are various causes that require an electric motor, pump or fan to be overhauled. All these causes can be remedied by applying certain activities. Elektromotoren Emmen has become a specialist in the field of overhaul in the last 40 years. As a result, Elektromotoren Emmen is able to perform all overhaul work based on the ATEX certification or Siemens certification. These activities also include the specialty of Elektromotoren Emmen such as winding a stator and balancing an anchor.
Standard procedure
The revision of an electric motor, pump or fan is an accurate process. This process must follow strict guidelines and procedures. One of these procedures is the standard procedure. The standard procedure includes the following activities: external cleaning, disassembly, internal cleaning, electrical testing, mechanical check of ball bearing fits, winding drying, impregnation (if necessary), renewal of bearings, assembly and no-load testing, color spraying and a written report of the work performed.
ATEX procedure
In addition to the standard activities, there are also activities that fall under the ATEX procedure. The ATEX procedure includes the following activities: vibration analysis before and after overhaul, balancing, measuring bearing fits, measuring shaft throughputs, visually checking fitting surfaces, measuring blocking current and a ring magnetization test. When the required work has been carried out, an Ex report is prepared. This report states that the electric motor, pump or fan meets the ATEX guidelines. In addition, Elektromotoren Emmen also provides an EX certificate for the relevant electric motor, pump or fan. This is necessary to be able to demonstrate that an electric motor, pump or fan meets the ATEX guidelines.
Wrap
If there is damage present in the windings, there are two options to fix it. The first is to purchase a new electric motor, but this is not always possible. If an electric motor has received adjustments or is tailor-made, the new delivery can take a lot of time. In this case it is faster and cheaper to rewind the windings. By rewinding, an electric motor has new windings in the very short term. Elektromotoren Emmen only wraps by hand in order to guarantee the life of the windings in this way.
Balancing
An imbalance in an electric motor, pump or fan causes complications that cause problems for the installation. This imbalance can be remedied by applying the balancing of parts in an electric motor, pump or fan. However, balancing an electric motor, pump or fan is a job that requires a lot of knowledge and experience. For this purpose, Elektromotoren Emmen has a specialist in the field of balancing within the company with more than 40 years of experience. This experience is applicable on all fronts because Elektromotoren Emmen has two balancing benches.
