High-efficiency 3-phase and single-phase electric motors engineered for heavy industrial, agro-processing and pumping duty
Electric motors account for over 70% of total electrical energy consumption in industrial facilities and commercial buildings. Nairobi Power Engineers supplies premium three-phase squirrel cage induction motors and heavy-duty single-phase motors engineered to international IEC 60034 standards.
As stockists for world-class motor manufacturers including ABB, WEG, and premium European brands, we stock motors from 0.18 kW to 315 kW in IE2 High Efficiency and IE3 Premium Efficiency classes, featuring rugged cast iron or aluminium frames, IP55/IP65 ingress protection, Class F/H insulation, and tropicalized windings.
Three-Phase • 0.37 kW to 315 kW
Heavy-duty 400V 3-phase motors in 2-pole (3000 rpm), 4-pole (1500 rpm), 6-pole (1000 rpm), and 8-pole (750 rpm) configurations.
IE3 Premium • Energy Saving
Top-tier efficiency motors engineered to cut plant electricity consumption, reduce operating temperatures, and provide VFD-ready inverter duty.
Single-Phase • High Starting Torque
230V single-phase motors equipped with centrifugal starting switch and run capacitor (Cap Start / Cap Run) for high starting torque loads.
