HPS Series IE5 / without VFD

Made in Italy  

Lafert Group's permanent magnet synchronous motors offer IE5 and IE6 energy efficiency and combine the advantages of asynchronous and servo technologies.

HPS Series IE5 / Permanent magnet synchronous motors achieving energy efficiency level IE5 Ultra Premium Efficiency.

They combine the electrical design of brushless servo motors with the mechanical design of asynchronous motors.

The motors in this series ensure high efficiency and strong torque across the entire speed range.

They are suitable for both quadratic torque and constant torque applications.

These applications require high performance during continuous operation with variable speed. In such a duty cycle, the difference in efficiency accumulates over the entire service life.

Technical characteristics of the HPS IE5 series:

• Power rating from 0.18 kW to 37 kW
• Torque from 2 Nm to 190 Nm
• Frame sizes from 56 to 160
• Speed up to 4500 rpm
• IPM or SMPM design
• IEC mounting forms (B14, B5, ...)
• NEMA mounting design and PAD mounting design
• Protection rating IP55
• Sensorless control or with speed transducer
• Up to 50% reduction in size and weight

What IE5 Ultra Premium Efficiency means

IE5 Ultra Premium Efficiency is an energy efficiency level under IEC TS 60034-30-2:2016.

For a 7.5 kW motor at 3000 rpm, efficiency rises from 90.1% at level IE3 to 92.4% at level IE5.

Over 6000 operating hours per year this means around 1240 kWh less energy consumed, multiplied by the electricity price at the specific site.

The same motor moves from frame size 132 to frame size 112, and the weight drops from 53 kg to 26 kg.
