Three phase electric motors – scope and exclusions
Scope
The Standard specifies the method of determining the performance characteristics of three-phase electric motors.
Exclusions
Motors that do not need to comply with MEPS include:
- Motors normally submersed in a liquid
- Motors integral with the equipment, that cannot be separated e.g. some gear motors
- Motors that run on different speeds by using switchgear to reconfigure the connection of windings (variable or multi-speed motors)
- Motors rated (S2) for short duty applications such as hoists and roller doors
- Rewound motors (except when the supplier claims it meets one of the efficiency levels in the standard)
- Motors granted exemption by EECA due to key design aspects.
