15  Conducting tests

General requirements

             (1)  Subject to subsection (2), the motor’s efficiency must be tested in accordance with the requirements mentioned in subclause 6.1.3 of IEC 60034-2-1 Ed. 2.0 (Method 2-1-1B – Summation of losses, additional load losses according to the method of residual loss).

Special requirements—totally enclosed air over motors

             (2)  For totally enclosed air over motors, the testing requirements specified in subsection (1) must be met while using an externally and independently generated air-stream, at laboratory ambient air temperature, directed over the motor’s stator from the non-drive end, with air-flow parallel to the motor’s shaft at the minimum declared air velocity specified by the manufacturer for normal operation of the product.

             (3)  For tests conducted according to subsection (2):

                     (a)  measurement of the externally-generated air flow velocity must be made using a hot-wire anemometer, or similar, type instrument; and

                     (b)  efficiency measurements must be carried out using the same procedure as for products subject to the requirements of subsection (1) only; and

                     (c)  the power required to generate the air-stream must not be counted against the results for the motor under test.

             (4)  In this section:

totally enclosed air over motor means a frame surface cooled machine, the exterior of which is cooled by a ventilating means external to the motor, for example by a fan.


Part 4—GEMS labelling requirements

                     (a)  this Determination is revoked in accordance with paragraph 35(1)(a) of the Act; and

                     (b)  another GEMS determination (the replacement determination) is made in accordance with paragraph 35(1)(b) of the Act; and

                     (c)  a transitional GEMS labelling requirement (the replacement requirement) of the replacement determination  provides that, if the replacement requirement is complied with, the revoked requirement is taken to be complied with.

The last row of this table is not relevant in relation to paragraph 14(1)(a) of this Determination, as a motor covered by this Determination cannot have a rated output power of 185 kW. See paragraph 11(1)(a) of this Determination.

                   For a motor with a rated output power between values specified in Table 2, the minimum efficiency is the relevant amount worked out in accordance with paragraph 14(1)(b) of this Determination. The last row of this table is relevant in relation to paragraph 14(1)(b) of this Determination.

Note 2:       The values in this table are equivalent to the efficiency requirements for IE2 (High Efficiency) levels in the IEC framework.

Note 1:       For a motor with a rated output power specified in Table 3, the high efficiency level is the relevant amount specified in the table. See paragraph 21(1)(a) of this Determination. The last row of this table is not relevant in relation to paragraph 21(1)(a) of this Determination, as a motor covered by this Determination cannot have a rated output power of 185 kW. See paragraph 11(1)(a) of this Determination.

                   For a motor with a rated output power between values specified in Table 3, the high efficiency level is the relevant amount worked out in accordance with paragraph 21(1)(b) of this Determination. The last row of this table is relevant in relation to paragraph 21(1)(b) of this Determination.

Note 2:       The values in this table are equivalent to the efficiency requirements for IE3 (Premium Efficiency) levels in the IEC framework.
