Draft Thai Industrial Standard for Rotating Electrical Machines Part 30-101 Efficiency Classes of AC Three Phase Induction Motors (TIS 866 Part 30(101) - 2561(2019)) (9 page(s), in Thai)
The Thai Industrial Standards Institute (TISI) has proposed the draft compulsory Thai Industrial Standard for Rotating Electrical Machines Part 30-101 Efficiency classes of AC three phase induction motors (TIS 866 Part 30(101) -2561(2019)). The coverage of standard includes scopes; definitions and symbols; classifications; and efficiency classes of AC three phase induction motors for single speed electrical motors that are rated in accordance with TIS 866 Part 1 (Identical IEC 60034-1:2014), and rated for operation on sinusoidal voltage supply and:
· have a rated power PN from 0.12 kW to 375 kW;
· have a rated voltage UN above 50 V up to 1 kV;
· have 2, 4, 6 or 8 poles.
The energy efficiency classes are IE1, IE2, IE3 and IE4. The testing method is in accordance with TIS 866 Part 2(1) (Identical IEC 60034-1:2014)
