What is IEC 60034-27-1:2017 ?

IEC 60034-28:2017 is a technical standard that aims to establish a common set of guidelines and requirements for manufacturers, users, and regulators to ensure the energy efficiency of single or multi-speed, continuous duty rating, and low-voltage three-phase cage induction motors. The standard is part of the IEC 60034 series, which specifically focuses on the efficiency classes of these types of motors.

The key requirements of IEC 60034-28:2017 are as follows:

3.Efficiency Classes

The standard defines four efficiency classes for single-speed, multi-speed, and continuous duty rating motors, which are labeled as C, B, A, and F, respectively. These classes are based on the efficiency of the motor and are used to determine the energy efficiency of the device.

3.Performance Test

The standard requires manufacturers to perform a series of tests to verify the performance of their motors. These tests include a thermal test, a vibration test, and a electromagnetic interference (EMI) test. The tests are designed to ensure that the motors operate efficiently and safely in a variety of environments.

3.Safety

The standard emphasizes the importance of safety in the design and use of motors. It sets guidelines for the use of protective devices, such as fuses and circuit breakers, to protect against overcurrents, overheats, and other hazards.

3.Environmental Considerations

The standard takes into account environmental factors such as temperature, humidity, and vibration. It requires manufacturers to consider these factors when designing their motors and to ensure that they meet the requirements of the standard.

3.Documentation

The standard requires manufacturers to provide documentation for their motors, including a technical file and a declaration of conformity (DoC). These documents must be used to ensure that the motors are designed and manufactured in accordance with the requirements of the standard.

ConclusionIEC 60034-28:2017 is an important standard that establishes guidelines and requirements for manufacturers, users, and regulators to ensure the energy efficiency of single or multi-speed, continuous duty rating, and low-voltage three-phase cage induction motors. By following the key requirements of this standard, manufacturers can ensure that their motors are safe, reliable, and efficient, while also reducing their environmental impact.
