Cost-effective DC motor solutions

Third Quarter 2019 Electrical switching & drive systems & components

Vert Energy’s Leroy-Somer LSK direct current DC motors provide cost-effective solutions for variable speed applications. The major advantage of direct current motors is the ease of effecting accurate speed control, and LSK’s advanced technology enables motors to respond to electronic controllers, which place great demands on the performance of DC motors. Smooth running is achieved by the introduction of an advanced frame design, incorporating the largest dimensioned shaft. LSK square laminated frame DC motors, which have been designed by Leroy-Somer to the latest European standards for industrial requirements, have ratings from 2 to 750 kW. Leroy-Somer also produces non-standard motors, providing a range of power from 0,06 to 18,5 kW.

Vert Energy’s LSK DC range includes enclosed permanent magnet motors, enclosed wound motors, drip-proof wound motors and drip-proof, force-cooled wound motors. These motors can be foot, flange or foot and flange mounted. Flanges are incorporated into the steel stator castings, giving a robust construction that eliminates vibrations. Four removable plates allow direct access to brushes for easy replacement, thus simplifying maintenance. Leroy-Somer’s advanced design of the DC motor incorporates cooling and ventilation systems that reduce wear and tear on the brush gear, by the elimination of dirty particles. These motors, with a Class H insulation system, can operate at ambient temperatures of between 5 and 40°C and are protected with a range of surface treatments that withstand harsh environments. The quality of the winding, insulation and impregnation guarantees optimum performance, even in arduous conditions.
