New European regulation EU 2019/1781 on minimum electric motor efficiency

The new European regulation (regulation EU 2019/1781) establishes new requirements for brake motors rated for operation on a 50 Hz, 60 Hz or 50/60 Hz sinusoidal voltage, rated voltage above 50 V and up to and including 1000 V and continuous duty (S1, S3 ≥ 80%, S6 ≥ 80%) operation, starting from the 1st of July 2021.
Starting from the 1st of July 2021:
- three phase brake motors with rated power 0,75 kW ≤ PN ≤ 1000 kW with 2, 4, 6, 8 pole, must be IE3.
- three phase brake motors with rated power 0,12 kW ≤ PN < 0,75 kW with 2, 4, 6, 8 pole, must be IE2.
Starting from the 1st of July 2023:
- single phase brake motors with rated power PN ≥ 0,12 kW with 2, 4, 6, 8 pole, must be IE2.

The new regulation doesn’t apply to some types of motors among which 2 speed motors and TENV motors.
