Explore our precision-engineered high-voltage and low-voltage electric motor configurations customized for demanding industrial applications worldwide.
In the context of the global green transition, industrial electric motors consume approximately 45% of global electricity. Elevating standard efficiency profiles to Premium Efficiency levels (IE3 according to IEC 60034-30-1) is no longer a regulatory option; it is a critical optimization strategy for modern enterprises to reduce operating costs and eliminate system losses.
Under the IEC 60034-30-1 standard, the IE3 designation represents Premium Efficiency. Compared to legacy IE1 or standard IE2 configurations, IE3 motors decrease energy losses by up to 15-20%. This is accomplished by utilizing superior electromagnetic materials, optimizing core stator structures, and reducing windage and stray load losses.
To reach IE3 benchmarks, the internal stator and rotor require highly refined manufacturing. Our processes include the integration of high-density copper windings to lower I²R losses, optimized magnetic circuits via high-grade cold-rolled silicon steel laminations, and tight structural tolerances to minimize mechanical drag.
Industrial applications rarely accommodate one-size-fits-all hardware. Our technical division designs and manufactures bespoke shafts, custom flange mounts, protective enclosure grades (IP55, IP56, IP65), and specialized insulation classes (Class H, Class F) to integrate seamlessly with your existing infrastructure.

SIMO Motor established and led by government in Xi'an, marking the foundation of a legacy industrial brand.
Relocated to a newly constructed manufacturing plant in Xi'an city to ramp up output capacity.
Renamed to Xi'an Motor Factory following strategic government-led acquisitions and industrial integration.
Successfully reformed from a state-owned factory into a highly flexible limited liability corporation.
Simo Motor Group established, expanding our industrial ecosystem with 14 specialized subsidiaries.
Relocated manufacturing bases to a brand new high-tech facility featuring modern machining lines.
Rebranded to Tech Full Simo Motor, optimizing internal assets for globalization and export dominance.
Operating with 3 key manufacturing plants, 1 subsidiary, and more than 1172 sets of advanced equipment to lead the global high-efficiency motor supply chain.
To understand how an OEM Motor Efficiency IE3 configuration cuts costs, we must analyze the electrical loss components within AC induction motors. By optimizing stator and rotor geometries and copper-fill coefficients, SIMO motors achieve premium operating performance.
| Motor Efficiency Standard | Stator & Rotor I²R Losses | Stray Load Loss (SLL) Mitigation | Core Lamination Material | Typical Power Range Coverage |
|---|---|---|---|---|
| IE1 (Standard Efficiency) | Baseline values; standard round wire winding. | Determined by basic estimation methods. | Silicon steel sheets with standard core losses. | 0.35kW to 1000kW |
| IE2 (High Efficiency) | Reduced stator resistance; thicker conductor gauges. | Mitigated via optimized rotor slot geometries. | Semi-processed low-loss electrical steels. | 0.35kW to 1500kW |
| IE3 (Premium Efficiency) | Optimized slot shapes; maximum copper slot fill factor. | Measured precisely using low-tolerance tests. | Thin, cold-rolled non-oriented silicon steel (high grade). | 0.35kW to 25,000kW |
| IE4 / IE5 (Super & Ultra Premium) | Permanent magnet assisted/Synchronous Reluctance technology. | Minimized to negligible levels. | Premium thin silicon iron laminations. | Up to 15,000kW (mostly low-voltage) |
Our R&D team utilizes advanced electromagnetic design software to simulate and eliminate losses in three critical zones:
China is home to the most integrated electromechanical supply chain in the world. From direct access to domestic rare earth elements (crucial for permanent magnet IE4/IE5 motors) to high-grade cold-rolled electrical steels and high-purity copper casting materials, SIMO enjoys immediate, cost-competitive material access.
Through decades of engineering experience, our plants have developed manufacturing setups that switch between standard runs and specialized OEM orders (e.g., custom voltages like 6kV/10kV, tailored shaft configurations, explosion-proof housings) without causing system delays or cost inflation.
Our Xi'an facilities houses advanced quality testing stations. Our facilities can load-test high-voltage motors up to 25,000 kW under full operating conditions to verify real-world heat generation, noise limits, structural vibrations, and actual efficiency metrics before shipment.
