STM Neri MR IE3 Motor 4.0kW 3 Phase 8 Pole Frame Size 160 Flange Mount B14

STM Neri MR IE3 motors are high‑efficiency stainless steel three‑phase induction motors designed for demanding wash-down, food, beverage and pharmaceutical environments where hygiene, reliability and low energy consumption are critical. Built to IE3 efficiency class, they help reduce operating costs and environmental impact while maintaining consistent performance in continuous duty applications.

Key features

• Three‑phase asynchronous design for reliable power transmission and smooth operation in industrial machinery.
• Stainless steel construction with IP69K protection, ideal for aggressive cleaning, high‑pressure wash-down and corrosive environments.​
• IE3 high‑efficiency class to meet modern energy‑saving standards and reduce lifecycle costs.
• Wide operating range, typically from 0.18 kW to 7.5 kW with speeds from approximately 920 to 2940 rpm, suitable for conveyors, mixers, pumps and packaging lines.
• Multi‑voltage capability (common options include 240 V, 380 V, 400 V and 690 V) for flexibility across different installations and regions.​
• Robust torque output (around 0.61 Nm to 49.1 Nm depending on size) for both light and heavy duty applications.​

Benefits in application

• Ensures hygiene and easy cleaning in food and pharma plants thanks to smooth stainless surfaces and high ingress protection.​
• Lowers energy usage and running costs over the motor’s life through IE3‑class efficiency and optimised induction design.
• Minimises unplanned downtime with robust construction tailored for continuous S1 duty in harsh environments.
• Simplifies integration with IEC‑compliant dimensions and common three‑phase supply voltages, making upgrades and replacements straightforward.
