The Lenze MF is an energy-efficient three-phase AC motor designed specifically for inverter operation. Combined with an 8400 motec frequency inverter mounted on the motor, it forms a compact decentralised drive covering 0.55 … 7.5 kW and 1.5 … 20 Nm.
The pairing suits tasks that need a wide speed setting range from a small motor: torque stays constant over a setting range of up to 1:24, and the drive responds more dynamically than a conventional three-phase AC motor. Efficiency is above class IE2, and the motors are optimised for use as geared motors with g500 gearboxes.
B3, B5, B9 and B14 mounting designs are available, and resolver, absolute value encoder or incremental encoder can be selected as feedback. The MF + 8400 motec combination belongs to Lenze's previous product range; Euronorm can advise on availability and successor solutions for existing plants.
Features
Integrated 8400 motec
Speed control takes place directly at the motor, so the drive can be used universally.
Setting range up to 1:24
Constant torque over a wide speed range allows a smaller motor to be selected.
Above IE2 efficiency
The inverter-optimised MF design exceeds the requirements of efficiency class IE2.
More dynamic response
The motor reacts faster to speed changes than a conventional three-phase AC motor.
Flexible feedback and mounting
Resolver, absolute value or incremental encoder and B3, B5, B9 or B14 designs are available.
Applications
- Drives requiring a large speed setting range
- Compact machine designs
- Conveyor and transport systems
- Spare and replacement drives in existing plants
