3 Tr a d i t i o n I n n ovation Q u a l i t y ELPROM-ZEM Co. a joint stock company is the biggest manufacturer of rotating electrical machines in Bulgaria with more than sixty years of experience in their manufacturing. Our production is well known in all countries of CIS and East Europe, as well in many West European countries, Asia, Africa and Latin America. The company employs more than 280 highly specialized employees and many costumers rely on our services. As a result of the changes, which occurred in the Bulgarian society and its orientation to the market economy, the company has been privatized in 1997 and 97% of the capital is a private property. The main share holder, possessing the control package of shares is Industrial holding Bulgaria. ELPROM-ZEM Co. manufactures and sells a wide range of electric machines, such as: Low voltage asynchronous electric motors with squirrel cage rotor for common industrial use, series M, MO, MOM and A, as per the requirements of the IEC, DIN and CENELEC, with degree of protection IP 23, IP 44, IP 54 and IP 55, from 2 to 8 poles, power outputs from 11 up to 315 kw, for rated voltage 380 V, 50 Hz, with shaft height from 160 up to 355 mm. Different types of enclosures are possible as well as other rated voltage. The newest AD series electric motors are tested and certified with CE, signed by TUV-Rheinland. High voltage asynchronous electric motors with squirrel cage rotor for rated voltage 3 kv and 6 kv, series A, in accordance to IEC and DIN, wit degree of protection IP 23, from 2 up to 8 poles, power output from 200 kw up to 1000 kw and shaft height from 355 up to 450 mm. High voltage asynchronous electric motors with squirrel cage rotor for rated voltage 6 kv, power output from 315 kw up to 2000 kw, designed according to individual customer s requirements. Synchronous electric motors for driving of mills, compressors, water pumps, etc., rated voltage up to 10 kv, power output up to 9000 kw, and asynchronous electric motors designed for special conditions of operation for driving of water pumps in Nuclear Power Plants, blowers and belt conveyors in Thermal Power Plants and mines, with power up to 3150 kw. NEW STANDARD FOR MOTOR S EFFICIENCY CLASS (IE-Code) According to IEC :2010 standard, new efficiency classes are defined for single-speed, three-phase cageinduction motors (IE-code). The following three power classes are created from 0,75kW to 375 kw and 2-, 4- or 6-poles: IE1 Standard Efficiency IE2 High Efficiency IE3 Premium Efficiency With the purpose of reducing energy consumption in worldwide significance (motors consume between 30% and 40% of the world s produced energy) From June , motors shall not be less efficient than the IE2 efficiency level. From January motors with a rated output of 7,5kW to 375 kw shall not be less efficient than the IE3 efficiency level From January all motors with a rated output of 0.75kW to 375 kw shall not be less efficient than the IE3 efficiency level The following motors are excluded from IEC : Motors made solely for converter operation; Motors completely integrated into a machine (for example, pump, fan or compressor) that cannot be tested separately from the machine Motors from ELPROM-ZEM Co. correspond with IEC :20 and reach requested values of efficiency as per efficiency IE1 class (for series M, MO and MOM) and IE2 class for series AD. Elprom-ZEM co. is actively involved in the idea of protection of natural resources and we offer for our clients with green orientated special manufactured motors from AD+ serias from category IE3 (with high efficiency Although according to the standard shall IE3 class to be produced after January HOW WE ACHIEVE HIGH ENERGY EFFICIENCY? By magnetic losses reduction: A significant part of the losses in the electrical motors are magnetic losses. This is why we reduce them by using better electrotechnical steel and by this we reduce losses in no load mode. Reducing electrical losses: We achieve this by using hi-tech insulation systems, which allow reducing insulation thickness and increasing the copper in the motor slots. By reducing mechanical losses: We use special fans, which reduce mechanical losses. In our efforts to reduce them further, we implement only the bearings from reputable manufacturers with proven effect. WHAT DO YOU BENEFIT BY BYING IE3 CLASS MO- TORS? Lower energy costs: Through increased energy efficiency our motors consume less amount of electricity compared to other classes and you pay less for it. Lower noise levels: Noise at work issues were significantly reduced in the motors class IE3 due to the fans and bearings we use. According to the IEC :2010 standard, the motor s nameplate has to be labeled with class efficiency (IE - the code) and its value as a percentage.

If the motors are operating in dusty or moisture conditions, replacement of the grease should be done more often, according the operation conditions. The cells of the bearings caps should be fulfilled with grease up to 50% of its capacity. 14
