Bernati’s BMT three-phase motor series is built within a cutting-edge technology, with a simple and robust design and in compliance with IEC standards. BMT three phase aluminium motors covers the product range with outputs from 0.18kW to 18.50kW in frame sizes IEC56 to IEC160, in either 2,4,6 or 8 pole speeds. The aluminium cast ensures high resistance to corrosion and atmospheric attack, and has a much lighter weight when compared to cast iron frames.

With a remarkably short payback period, they offer significant savings over IE2 and IE3 motors along with a host of technologically superior features. Between some of the main advantages of IE4 class of efficiency motors is a higher level of efficiency and a higher power factor at all loads.

Bernati’s BMT IE4 Super Premium performance, ensures an improved horsepower per frame size, a wide range of torque and higher lifespan. It provides greater efficiency, quality and saving for the industry.

Standards compliance

These motors comply with the latest efficiency standards and requirements of IEC 60034-30-1;2014. They have a proven high quality, reliability and performance.

Additional info

Bernati motors with IE3 and IE4 efficiency classes, only from 0.75kW on up, come equipped with a positive temperature coeficiente (PTC) thermistor. Therefore, in these cases, when resistance increases as coil temperature reaches values defined by the insulation class F, a signal is sent to the motor’s control unit in order to protect the motor and increase its operating lifetime. Upon request, the PTC thermistors can be installed in all other ranges where this protection is not standard.
