IEC 60034-28 Ed. 1.0:2007 (b)

Rotating electrical machines - Part 28: Test methods for determining quantities of equivalent circuit diagrams for three-phase low-voltage cage induction motors

Applies to three-phase low-voltage cage induction motors of frame numbers 56 to 400 as specified in IEC 60072-1. Establishes procedures to obtain values for elements of single phase equivalent circuit diagrams from tests and defines standard elements of these diagrams.

-------------------------------------------------------------------------------------------

IEC 60034-29 Ed. 1.0:2008 (b)

Rotating electrical machines - Part 29: Equivalent loading and superposition techniques - Indirect testing to determine temperature rise

IEC 60034-29 provides various indirect load tests, the purpose of which is to determine the temperature rise of rotating electrical machines, including a.c. induction machines, a.c. synchronous machines and d.c. machines. The test methods in some cases provide, in addition, means of measuring or estimating other parameters such as losses and vibration. Applies to machines covered by IEC 60034-1 when they cannot be loaded to a specific condition. Is applicable to both motors and generators.

IEC 60034-30 Ed. 1.0:2008 (b)

Rotating electrical machines - Part 30: Efficiency classes of single-speed, three-phase, cage-induction motors (IE-code)

IEC 60034-30:2008 specifies efficiency classes for single-speed, three-phase, 50 Hz and 60 Hz, cage-induction motors.
