What is PD IEC/TR 63021 – Rotating electrical machinery about?
PD IEC/TR 63021 is an international standard that discusses the natural graphite brush for slip-ring in wound rotor-type induction motor for rotating electrical machinery. Rotating electrical machinery produces the electromotive force that moves in the magnetic field, which generates electrical currents through the conductors.
PD IEC/TR 63021 presents technical characteristics, application results and practical information on NG-brush for slip-ring obtained through the application of NG-brush in various kinds of wound rotor-type induction motor (large-size water pump, belt conveyer, lift, winder motor, grinding mill and crusher in coal or ore mine; crane, rolling mill, compressor and winder motor for boring in oil or gas facility).
Who is PD IEC/TR 63021 – Rotating electrical machinery for?
PD IEC/TR 63021 on rotating electrical machinery applies to:
- Manufacturer of electric machines
- Quality testing personnel
- Electrical engineer
Why should you use PD IEC/TR 63021 – Rotating electrical machinery?
The rotating electrical machine consists of a stator, rotor and the air gap between them. The stator and rotor have windings. The rotor is installed into the stem, and the stem connects to the motor and any other loads.
PD IEC/TR 63021 provides various types of conditions for brush and slip-ring in wound rotor-type induction motors such as fire-spark, life, temperature, dust diffusion and noise. It also provides operating characteristics of natural graphite brush for slip-ring in a wound rotor-type induction motor such as current density, vibration along with ability, temperature and brush’s pressure. This helps in manufacturing good quality rotating electrical machinery.
PD IEC/TR 63021 exemplifies the required application for natural graphite brush for slip-ring in wound rotor-type induction motor for rotating electrical machinery.
