What is BS EN IEC 60034‑2‑3 - Rotating electrical machines about?
BS EN IEC 60034‑2‑3 is a multi-part series in European standard which discusses about rotating electrical machine. BS EN IEC 60034‑2‑3 specifies test methods and an interpolation procedure for determining losses and efficiencies of converter-fed motors.
BS EN IEC 60034‑2‑3 applies the approach of the comparable converter, the motor efficiency determined for comparison of different motor designs only.
BS EN IEC 60034‑2‑3 specifies procedures to determine motor losses at any load point with the base speed range based on determination of losses at seven standardized load points.
Who is BS EN IEC 60034‑2‑3 - Rotating electrical machines for?
BS EN IEC 60034‑2‑3 on specific test methods for determining losses and efficiency of converter-fed AC is useful for:
- Manufacturer of electrical rotating machines
- Suppliers and distributors of electrical rotating machines
- Companies dealing with converter-fed AV motors
Why should you use BS EN IEC 60034‑2‑3 - Rotating electrical machines?
Rotating electrical machines consists of rotor, stator and air gap between them. Stator and rotor consist of windings, in which rotor is installed in the stem and that stem connects to the motor and any other loads.
The objective of BS EN IEC 60034‑2‑3 is to provide test methods for determining total losses including additional high frequency motor losses and efficiency of converter-fed motors.
BS EN IEC 60034‑2‑3 provides general terms such as: motor losses with converter supply which is when powered by a converter, motor losses are a combination of losses caused by fundamental frequency and losses caused by the converter high frequencies, fundamental losses, additional high frequency losses, base speed range and switching frequency. It helps for manufacturing a good quality of converter-fed motor in rotating electrical machines.
As a buyer of BS EN IEC 60034‑2‑3, it provides the test procedure which is conducted with converter and an assembled motor with the essential components in place, helps obtain test conditions equal or very similar to normal operating conditions.
What’s changed since the last update?
BS EN IEC 60034‑2‑3:2020 supersedes PD IEC/TS 60034‑2‑3:2013, which is withdrawn. BS EN IEC 60034‑2‑3:2020 has re-dated normative references with respect to PD IEC/TS 60034‑2‑3:2013.
