m500/m550/m650/MF + i550/i650 motec motors with integrated frequency inverter 0.25–22 kW

Technical specifications

Specifications are taken from the manufacturer’s technical documentation. Updated 11/06/2026.

Description

The m500 of classes IE2/IE3 is combined with the i550 motec at 0.25–7.5 kW (1.7–48 N·m) and with the i650 motec at 0.25–5.5 kW (1.7–35 N·m). The MF with a control range up to 1:24 works with the i550 motec at 0.55–18.5 kW (1.5–50 N·m), and the m550-U of class IE5 gives 0.37–11 kW (1.9–56.5 N·m). The m650-U of class IE5 at 120 Hz is two frame sizes smaller than an IE2/IE3 motor of the same power and covers 0.75–22 kW, while the m550-V of class IE6 covers 0.25–7.5 kW (1.2–38.5 N·m). Classes IE5 and IE6 are confirmed under IEC TS 60034-30-2, and Grade 2 and Grade 1 under GB 30253-2024. Starting torque reaches 250 % for IE5 and 300 % for IE6; the MF and m500 also have B9. Combinations with the 8400 motec at 0.12–7.5 kW were formerly made. The integrated inverter has four IO-Link ports, a regeneration module and EtherCAT, EtherNet/IP, Modbus RTU/TCP and PROFINET interfaces. The i650 motec version adds a CODESYS logic PLC, table positioning and STO via CIP Safety.

How to choose

The m550-V is needed where class IE6 matters, the m550-U and m650-U give IE5 with sensorless control, and the m500 and MF remain for classes IE2/IE3 and wide control range. With the i650 motec the m550 and m650 motors give an overload torque of up to 300 % from standstill without a feedback sensor, according to a 2025 press release. The combination of motor, gearbox and drive reduces losses by up to 60 %, and built-in regeneration returns energy to the mains without braking resistors.
