Replacing the inverter in a standard high-voltage motor
Thread Content
Our facility uses 10KV/220KW motors driven by multi-stage pumps; we need to change the frequency. Does anyone here have experience with this? Are there any feasibility reports or relevant documents available? What will be the effect of the changes, and does it need to replace the motor with an inverter-driven motor? I would appreciate the guidance of experts from Haiyou. Thank you!
Electric motors generally do not need to be replaced, but operation at low speeds is not recommended, as this leads to poor heat dissipation. For high-voltage frequency converters, it is advisable to use brands such as Rongxin or Legrand, or opt for imported models. It’s best not to use Hekang. There are too many minor problems. I also suggest that you consider a permanent magnet speed regulator.
