How does The Ark create savings with electric motors?
As we know, Power (kW) is equal to the Voltage (V) multiplied by the Current (i), kW = V x I. Power into a 3-phase motor (kW in) is equal to the power out (kW out) plus system losses (heat and vibration). A motor running on higher voltage than required will have increased copper and iron losses for a similar power output, as well as poorer power factor. Hence the electricity consumed (kW in) significantly increases with an increase in voltage beyond a motor’s optimum capacity. With an Ark installation, the internal losses and the stress on motors is significantly reduced. An Ark installation enables motors and equipment on-site to operate within their optimal (and design specified) voltage range, while also improving power factor, 3-phase voltage balancing and reducing harmonic distortions. The net effect is that motors operate with greater efficiency. There is a significant reduction in internal losses and hence a net reduction in power usage for the same motor output. There is no eff
