New gears and drives

4th Quarter 2010 Electrical switching & drive systems & components

Gear units

The full range of Hydromec gear units is now available from Stone-Stamcor Drives Division. Manufactured in Italy, the Hydromec range comprises worm, helical, helical-bevel and parallel shaft gear units and geared motors. All are designed to accommodate standard IEC electric motors without the need for special adapters. Hydromec’s unique modular design enables each basic gear unit to be adapted to suit virtually any application by simply bolting on various off-the-shelf mounting attachments. This same feature also allows for simple drop-in replacement of any other leading brand of gear unit without modification to the existing machine. All units are assembled locally and filled with synthetic oil for lifelong lubrication, making them maintenance free. Stainless steel versions are also available for the food processing industry and harsh environment applications.

Variable speed drives

The new Var-Spe K-series variable speed drive is also now available. Well known for its robust construction and exceptional reliability, the Var-Spe hydrostatic variator has been remodelled to make it more adaptable and user friendly. The new patented modular design employs various standard bolt-on mounting components as well as a choice of different control options. Compared to most speed variators, the Var-Spe unit offers higher efficiency and a wider speed range from zero to full motor speed in both directions of rotation. High starting torque, frequent starts, reversibility and adjustable torque limitation are all standard features of this durable, ATEX compliant speed variator. Available from Stone-Stamcor, the Var-Spe K can be coupled to any standard IEC or Nema electric motor in the 0,37 kW to 4 kW power range whilst higher powers up to 22 kW remain available in the previous design format.
