MF three-phase motors for inverter operation 0.55–22 kW
Country: Germany · Model: MF
The MF four-pole three-phase asynchronous motors, 0.55–22 kW and 1–60 N·m, are designed for operation from a frequency inverter. Efficiency exceeds the requirements of class IE2, and the constant-torque control range reaches 1:24. They are taken where wide speed control is needed with minimal drive dimensions.

Description
As part of g500 geared motors, the motors are designed for 120 Hz from the inverter, and a smaller motor gives the same power. Versions B3, B5, B9 and B14. For positioning and closed-loop control the motors are fitted with a resolver, an absolute or an incremental encoder. The g500 gearboxes are helical g500-H at 4–3000 N·m, shaft-mounted g500-S at 5–4500 N·m and bevel g500-B at 8–4300 N·m. The motor works together with i510 cabinet, i550 cabinet and i550 protec inverters, as well as i550/i650 motec. Units with a built-in i550 motec cover 0.55–18.5 kW and 1.5–50 N·m, and versions with the 8400 motec at 0.55–7.5 kW and 1.5–20 N·m were formerly made. Since the motor is intended only for inverter operation, the requirements of Regulation (EU) 2019/1781 on the minimum class IE3 do not apply to it, according to the manufacturer's information letter. Motors suitable only for inverter operation are explicitly excluded from this rule.
How to choose
Here the control range and the gearbox are decisive. If the drive works over a wide speed range, the MF with control up to 1:24 suits better than an ordinary asynchronous motor. For requirements of a higher efficiency class look at the m550-U, m650-U or m550-V, and for mains supply at the m500 series. The MF series is available for inverter operation with wide control.

FAQ
What are the power and torque of the MF motors?
Power 0.55–22 kW, torque 1–60 N·m. The motors are four-pole.
What is the speed control range?
Up to 1:24 at constant torque. For feedback there is a resolver, an absolute or an incremental encoder.
Must the MF meet class IE3 under Regulation 2019/1781?
No, according to the manufacturer's information letter the minimum class IE3 requirements do not apply to motors for inverter operation only.
What mounting versions does the MF have?
Four versions, B3, B5, B9 and B14. For closed-loop control the motors are fitted with a resolver or an encoder.
What power does the MF with an integrated inverter have?
With the i550 motec 0.55–18.5 kW and 1.5–50 N·m. Formerly there was a combination with the 8400 motec at 0.55–7.5 kW.
