Tests

Testing of our electric motors is secured by our own laboratories, which are equipped with test equipment and apparatus, allowing us to undertake electrical and mechanical testing of the electric motors in accordance with the requirements of IEC 60034.Motors from IHB ELECTRIC correspond with IEC 60034-30:20 and reach requested values of efficiency as per efficiency IE1 class (for series M, MO and MOM) and IE2 class for series AD. IHB ELECTRIC is actively involved in the idea of protection of natural resources and we offer for our clients special manufactured motors from AD+ series from category IE3. Although according to the standard IE3 class to be produced after January 1 2015.

Energy efficiency

The energy efficiency value is the crucial benchmark of the electric motor. The higher the value is, the more benefits get the user.

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. In our company policy has set the rule for using materials of highest quality from veri-fied international suppliers.Reducing electrical losses:We achieve this by using hi-tech insulation systems, which allow re-ducing insulation thickness and increasing the copper in the motor slots. A milestone is using the Global VPI insulation system, which guarantees extended operation and reliability of the electric motor.By reducing mechanical losses:We have developed and 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 MOTORS?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.

The factory which is the manufacturer recommends lubrication of the bearing units to be performed by lithium grease for operation at -�0ºC ÷ +1�0 ºC, viscosity of 91 mm/s and consistency according

NLG-�. In the process of manufacturing is used grease “Litol ��”, in compliance to GOST �11�0-7�. Replacement of the grease at normal operation conditions should be performed after �000 hours of operation, but not less than once in a year. 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.
