The new European regulation (EU Regulation 2019/1781) establishes new requirements for brake motors designed to operate at a sinusoidal voltage of 50 Hz, 60 Hz, or 50/60 Hz, with a nominal voltage above 50V and up to 1000 V inclusive and continuous operation (S1, S3 ≥ 80%, S6 ≥ 80%), starting from July 1, 2021.
From July 1, 2021: – Three-phase brake motors with a rated power of 0.75 kW ≤ PN ≤ 1000 kW with 2, 4, 6, or 8 poles must have a minimum efficiency class of IE3. – Three-phase brake motors with a rated power of 0.12 kW ≤ PN < 0.75 kW with 2, 4, 6, or 8 poles must have a minimum efficiency class of IE2.
From July 1, 2023: – Single-phase brake motors with a rated power of PN ≥ 0.12 kW with 2, 4, 6, or 8 poles must have a minimum efficiency class of IE2.
The regulation does not apply to certain types of motors, including two-speed motors and motors without ventilation (TENV).
