IE5 m550-U Three-Phase Motor + i550 motec
IE5 m550-U three-phase motor with an integrated i550 motec inverter for 0.37–11 kW: IE5 efficiency and up to 40% lower losses than IE3.
Specifications
- Power
- 0.37 … 11 kW
- Torque
- 1.9 … 56.5 Nm
- Efficiency class
- IE5
- Mounting design
- B3, B5, B14
This drive unit pairs the IE5 m550-U three-phase motor with an i550 motec frequency inverter mounted directly on the motor, so speed is controlled at the machine rather than from the control cabinet. The integrated inverter makes the drive suitable for a broad range of speed-controlled tasks.
Compared with an IE3 motor, the m550-U lowers losses by up to 40% and reaches IE5 under IEC TS 60034-30-2 and Grade 2 under GB30253-2024. It provides up to 250% starting torque from standstill and is optimised for sensorless operation on Lenze inverters.
The combination covers 0.37 … 11 kW with torques of 1.9 … 56.5 Nm and is available in B3, B5 and B14 mounting designs. Connection via terminal box or standard plug connectors keeps commissioning quick.
Features
Integrated i550 motec
The inverter sits on the motor, enabling decentralised speed control without cabinet space.
IE5, up to 40% lower losses
Losses fall by up to 40% versus IE3, meeting IE5 (IEC TS 60034-30-2) and Grade 2 (GB30253-2024).
Up to 250% starting torque
High breakaway torque from standstill copes with heavy starts and frequent cycles.
Sensorless operation
The motor is tuned for encoderless control with Lenze inverters, which saves feedback hardware.
0.37–11 kW power range
Torques of 1.9 to 56.5 Nm are covered in B3, B5 and B14 designs.
Applications
- Conveyor lines with decentralised drive architecture
- Logistics and warehouse conveying systems
- Pump and fan drives
- Packaging machines
