For Gulf sites: heat, 60 Hz and Saudi IE3
- Saudi Arabia – SASO 2893: IE3 is mandatory for three-phase motors from 0.75 to 375 kW (380 / 400 V, 60 Hz). Choose IE3 or IE4.
- 60 Hz: three-phase single-speed motors are marked with a 50 Hz and a 60 Hz voltage range. On 60 Hz with proportionally higher voltage, speed rises by 1.2× and output by 1.15×. Windings for 380 / 400 V 60 Hz are available on request.
- Ambient above 40 °C: with class B temperature rise the rated output falls to about 95% at 45 °C, 90% at 50 °C, 85% at 55 °C and 80% at 60 °C. A winding utilised to class F needs no derating up to 55 °C – tell us your site temperature.
- Coastal and outdoor sites: special finish K1 for corrosive chemical and marine atmospheres, anti-condensation heaters and drain holes.

- Windings for special voltages and 60 Hz
Frequently asked questions
Are Lafert AMPE motors suitable for Saudi Arabia?
Yes. AMPE motors are IE3, the level required by SASO 2893 for three-phase motors from 0.75 to 375 kW. For Saudi 380 / 400 V 60 Hz networks we confirm the winding and nameplate data with the quotation.
What is the difference between AMPE and AMPH?
AMPE is the IE3 range rated for 400 V 50 Hz. AMPH is rated for 460 V 60 Hz and meets NEMA Premium efficiency (EISA), verified by UL.
What does the * on some models mean?
It marks higher-output (progressive) motors: more kW in the same frame size, useful when space is limited.
Can a 50 Hz IE3 motor run on 60 Hz?
Yes, if the voltage rises in proportion (for example 400 V 50 Hz to 460 V 60 Hz); speed then increases by 1.2 and output by 1.15. At unchanged voltage the output cannot be increased.
What do you need to quote a replacement?
The full type from the nameplate (for example AMPE 132M BA 4), mounting arrangement (B3, B5, B14…), voltage, frequency and quantity.
Need Lafert IE3 motors?
Send us the type, kW, poles and mounting – or a nameplate photo – and we reply with a quotation.
