More Cost-efficient • Up to 30 % more cost-efficient • Savings due to absence of the encoder • Only one power cable without any additional shielded wires Simpler Commissioning • Fewer parameters to consider • Reduced wiring effort • Reduced storage and logistics expenses Rugged • No encoder • Simpler on-site motor and cable repairs • Rugged spring-loaded holding brake Do you need an inexpensive and rugged alternative to a synchronous motor? Our LeanMotor offers you a world first: The new motor class is more cost-efficient and more rugged than a synchronous servo motor. It withstands high vibrations and oscillations and is therefore suitable for harsh production environments, for example. In addition to efficiency levels of up to 96 %, the STOBER LeanMotor offers you many more advantages: A NewMotor Class! The perfect link between the worlds of asynchronous and synchronous motors Is an AC motor too big and not efficient enough for you? Our LeanMotor offers an interesting alternative. Delivering the same output, the LeanMotor is significantly smaller and, as a result, lighter than an asynchronous motor. Other advantages: High Efficiency • IE5 efficiency (up to 96%) • Future-proof product for the global market Higher Power Density • Lower volume + weight with the same output • Reduction in installation space and machine size • More freedom in the machine design • Simple installation Compact and Rugged • Fanless servo-design • No electronics in the motor since the encoder is eliminated; comparable to an asynchronous motor with incremental encoder • Rugged spring-loaded holding brake Greater Dynamics • Larger speed adjustment range • Excellent acceleration performance • Enables faster processes • Dynamic regulation of speed and torque at lower speeds Efficiency of LeanMotor compared to asynchronous motors STRONG RUGGED PRECISE COMPACT 0.72 kW 1.4 kW 1.9 kW 2.9 kW 4.2 kW 6.2 kW 8.1 kW LeanMotor 84.64% 88.65% 89.96% 93.52% 94.57% 95.36% 96.01% 0.75 kW 1.5 kW 2.2 kW 3 kW 4 kW 7.5 kW 11 kW IE2 77.4% 81.3% 83.2% 84.6% 85.8% 88.1% 89.4% IE3 80.7% 84.2% 85.9% 87.1% 88.1% 90.1% 91.2% IE4 83.5% 86.5% 88% 89.1% 90% 91.7% 92.6% 100% 95% 90% 85% 80% 75% IE5 Efficiency Contact us today to see how we can help!
