Regal Rexnord
AC Motors - IEC
Regal Rexnord IEC AC motors provide the metric - frame, high - efficiency power solution for global industrial applications, aligning with IEC 60034 dimensional and performance standards that govern motor specification in Europe, Asia, the Middle East, and Latin America.Under the Marathon, LEESON, and Lincoln brands, our IEC motor portfolio spans frame sizes from 56 to 450, power ratings from 0.06 kW to over 1,000 kW, and efficiency classes from IE3 Premium to IE4 Super Premium — all engineered for the reliability and service life that industrial pump, fan, compressor, and conveyor drives demand in chemical, water, food - and - beverage, and general manufacturing facilities.Engineers specifying IEC motors for global projects or for equipment destined for international markets choose Regal Rexnord to meet the CE, UKCA, and regional efficiency regulations(such as EU MEPS) while providing the same rugged construction, bearing - life engineering, and application support they expect from a premier motor manufacturer.With aluminium and cast - iron frame options, multiple mounting arrangements(B3 foot, B5 flange, B14 face), and comprehensive inverter - duty ratings that ensure trouble - free VFD operation, our IEC motors provide the metric - flexibility and international - compliance features essential for globally deployed equipment.

Trusted by Industry Leaders
IE3 & IE4 Efficiency Class Compliance
Meet or exceed IE3 and IE4 efficiency levels per IEC 60034 - 30, reducing energy costs and meeting regulatory requirements in international markets — critical for equipment exported to the EU and regions with Minimum Energy Performance Standards(MEPS).
Multi - Mount Versatility(B3, B5, B14)
One motor frame can often be configured for foot, flange, or face mounting, reducing SKU proliferation and simplifying spares inventory for multi - national operations.
Inverter - Duty Windings for VFD Service
Spike - resistant insulation systems and symmetrical winding designs minimize the voltage - stress failures common with non - inverter - rated motors on VFDs, enabling reliable variable - speed operation.
Cast - Iron & Aluminium Frame Availability
Lightweight aluminium for OEM machine builders seeking reduced mass; robust cast - iron for harsh process - industry environments with vibration and corrosion.
Global Certifications & Documentation
CE, UKCA, EAC, and other regional marks, with full technical documentation packages supporting international equipment compliance and import -clearance processes.
Wide kW Range with Standardized Frames
From 0.06 kW fractional - power motors to 1,000 + kW large machines, all within standard IEC frame allocations that ensure physical interchangeability across competitor brands.
IEC Motors for Global Equipment OEMs
Machine builders exporting equipment to multiple world regions face a complex landscape of motor efficiency regulations, voltage / frequency standards, and certification requirements.Specifying a Regal Rexnord IEC motor with IE3 efficiency, multi - voltage capability(230 / 460V or 400 / 690V) and CE marking satisfies the majority of destination - country requirements, reducing the engineering cost and lead - time penalty of re - sourcing motors for each export market.Our IEC motors are supported by a global distributor network that can deliver replacement motors and parts to end - user sites in over 100 countries, ensuring that equipment uptime is maintained regardless of where the machine is installed.This global support infrastructure transforms the motor from a potential field - service liability into a reliability asset, enhancing the OEM’s brand reputation for dependability in international markets.
IE3 vs.IE4: Efficiency Class Lifecycle Cost Analysis
The decision between IE3 and IE4 efficiency classes involves comparing the incremental motor purchase cost against the energy savings over the motor’s operating life.For high - utilization applications — pumps and fans running 6,000 to 8,000 hours per year — the additional purchase cost of an IE4 motor is typically recovered in under 18 months through electricity savings, with every year thereafter representing pure cost reduction.For intermittent - duty or low - utilization applications, IE3 provides the optimal capital - cost / efficiency balance.Regal Rexnord application engineers can model the specific operating profile of your application, including local electricity rates and utility rebates, to quantify the payback period and lifecycle savings of IE3 versus IE4 motor selection.This analysis - driven approach ensures that the efficiency investment delivers real economic returns aligned with your organization’s capital - allocation criteria.
