Explore the complete portfolio of OEMER three-phase asynchronous, synchronous permanent magnet, and servomotors with comprehensive engineering specifications, power ratings, and industrial applications.
OEMER HQL & HQLa High-Performance Inverter-Duty AC Motors
The flagship OEMER HQL and HQLa Sincrovert three-phase inverter-duty asynchronous AC motors are engineered for demanding variable-speed industrial drives. Featuring a compact square-laminated stator frame with optimized radial cooling fins and integrated forced-ventilation servo blowers, they deliver full continuous torque at near-zero speeds and wide constant-power field-weakening capabilities. Class H insulation with vacuum pressure impregnation (VPI) ensures complete resistance against steep voltage spikes from modern PWM frequency inverters. Power ratings span from 0.55 kW to 1115 kW across shaft heights SH 80 to 355 mm with output torques reaching 6700 Nm. These motors are widely utilized in machine tool main spindles, plastic extrusion lines, industrial winders, calenders, and printing machinery.
0.55–1115 kW, SH 80–355 mm, torque up to 6700 Nm, forced cooling, VPI Class H.
The specialized OEMER HQLa-Li low-inertia AC asynchronous motor series is specifically developed for cyclic industrial machinery requiring rapid acceleration, frequent reversing, and precise positioning. The elongated rotor profile with reduced outer diameter cuts rotor inertia by up to 40% compared to standard motors of equivalent capacity, allowing unprecedented angular accelerations under minimal drive current. Covering a power band from 30 kW to 289 kW and nominal torques from 550 Nm to 2870 Nm in frame sizes SH 180, 225, and 280 mm, it features heavy-duty shafts and reinforced bearings engineered for severe cyclic shock loads. These motors are essential for flying shears, rotary cut-off saws, stamping presses, and automotive dynamic test dynamometers.
30–289 kW, SH 180–280 mm, -40% rotor inertia, torque up to 2870 Nm, rapid cyclic duty.
OEMER LQ Liquid-Cooled Closed-Loop Inverter-Duty AC Motors
The OEMER LQ series comprises heavy-duty liquid-cooled asynchronous inverter motors featuring integrated cooling jackets built into the stator housing. Continuous coolant circulation (water or glycol mixture) guarantees uncompromised thermal dissipation across the entire speed spectrum down to standstill. The totally enclosed IP54/IP55 construction eliminates fan noise and stops hot air exhaust into the plant floor. Rated from 3.2 kW to 456 kW across frame sizes SH 100 to 280 mm with torques from 40 Nm to 2660 Nm, LQ motors sustain 100% continuous duty torque at low speeds without thermal derating. They represent the premier solution for plastic extruders, rubber internal mixers, metal rolling mills, and cleanroom manufacturing environments.
3.2–456 kW, SH 100–280 mm, internal water jacket, IP54/IP55, low-noise sealed operation.
The OEMER QLS series represents premium three-phase permanent magnet synchronous servomotors engineered with high-coercivity NdFeB magnets for high-precision motion control applications. Surface-mounted rotor magnets ensure maximum power density, minimized inertia, and instantaneous dynamic acceleration. Exceptionally low cogging torque provides vibration-free smoothness even at crawling velocities. Delivering 4.5 kW to 176 kW with continuous torques from 46 Nm to 2300 Nm across frame heights SH 100 to 225 mm, QLS servomotors integrate multi-protocol absolute feedback devices (EnDat, Hiperface, DRIVE-CLiQ, SSI, resolvers) and optional integrated holding brakes. Ideal for CNC feeds, main spindles, injection molding machines, industrial robots, and high-speed packaging.
4.5–176 kW, SH 100–225 mm, torque up to 2300 Nm, NdFeB magnets, EnDat/Hiperface encoders.
OEMER QS Super Premium IE4 Permanent Magnet Motors
The OEMER QS series permanent magnet synchronous motor line is certified to the highest international energy efficiency standard IE4 (Super Premium Efficiency under IEC 60034-30-2). The complete elimination of rotor Joule losses yields electrical efficiencies exceeding 96% across wide operational load ranges from 25% to 120%. Built to standard IEC mechanical dimensions (foot B3, flange B5/B14), QS motors enable straightforward retrofitting for immediate energy savings. Delivering 1.7 kW to 200 kW and torques from 25 Nm to 1400 Nm in shaft heights SH 100 to 225 mm, they operate with significantly lower winding temperatures, extending insulation and bearing life. Optimal for continuous industrial pump stations, cooling tower fans, rotary compressors, and material handling conveyors.
1.7–200 kW, SH 100–225 mm, IE4 Super Premium efficiency >96%, standard IEC frame.
The innovative OEMER QSR synchronous reluctance motor series blends the rugged reliability of squirrel-cage induction machines with the high efficiency of synchronous drives. The rotor is engineered entirely from laminated electrical steel with tailored anisotropic magnetic barriers, containing no rare-earth magnets or aluminum bars. This eliminates any risk of thermal demagnetization during heavy overloads while delivering a cost-effective drive solution. Power outputs range from 0.3 kW to 500 kW with nominal torques from 5 Nm to 2500 Nm across frame sizes SH 80 to 280 mm. The unheated rotor design protects bearing lubricants from thermal degradation. Highly suited for textile machinery, industrial mixers, metering pumps, and continuous assembly line conveyors.
0.3–500 kW, SH 80–280 mm, magnet-free rotor, torque up to 2500 Nm, cool running.
The OEMER LTS and LTS-TB (Thrust Bearing) high-torque permanent magnet synchronous direct-drive motor series is engineered for heavy-duty gearbox-free industrial machinery. Direct shaft coupling eliminates mechanical backlash, gear wear, oil leakage, and transmission losses. The specialized LTS-TB variant integrates a heavy-duty spherical roller thrust bearing designed to absorb massive axial reaction forces generated by high-pressure extrusion screws. Delivering power ratings from 2.5 kW to 496 kW with massive continuous torques from 118 Nm to 14046 Nm across frame sizes SH 132 to 355 mm, hollow-shaft configurations are readily available. Key applications include single and twin-screw extruders, plastic injection molding, rubber calenders, coil winders, and heavy-duty winches.
