High Voltage Motors

Royals Electric offers a full range of high voltage asynchronous induction motors, including rib cooled squirrel cage motors, and modular slip-ring and squirrel cage welded steel frame motors with different cooling options. These motors are optimally designed, engineered and built for the toughest and most demanding industrial applications, using the state-of-the-art techniques and premium grade materials and components, featuring extra safety, reliability, durability, efficiency and productivity.


Slip-ring modular motors


These motors are used in applications requiring high starting torque or low starting current. They are especially suitable for heavy load inertia applications like mill drives or situations where network conditions are weak.

Slip-ring motors are built using proven standardized motor design, high-quality materials and advanced ventilation technology. This, combined with the fully-braced and vacuum pressure impregnated(VPI) windings, ensure they are extremely efficient and reliable.


Squirrel-cage modular motors


Built on the most successful modular motor platform, they comply with all relevant international standards, are optimized for variable speed control and undergo rigorous testing at every stage of production.


Rib-cooled squirrel cage motors


These multi-purpose motors provide a unique combination of small size, high power density, high reliability, low losses and easy maintenance. Versions specifically designed for use with variable speed drives are also available. VSD control generally means even higher efficiency and precise process control in both quadratic and constant torque applications.

Losses have been minimized by the effective use of material and optimized fan designs. Reduced core and fan losses mean there is no sharp drop in the efficiency curve at partial load.

Typical applications include pumps, fans, blowers, compressors, conveyors, pulverizers, and even ship thrusters and AC generators. These motors are an excellent choice for driving pumps in power plants and process industries, as well as many other continuous duty applications.
