Government regulations mandate greater energy-efficiency and reduced environmental emissions. Electronically driven motors,mainly categorised under 3 types given below, aim to meet these requirements.
(1) DC Brushless drive (BLDC)
(2) Switched Reluctance Drive (SRM)
(3) Controlled Induction Motor (CIM) or ac variable frequency drive (AC VFD) -
When these three types are evaluated in terms of efficiency, BLDC gives the highest efficiency, SRM with medium efficiency and CIM / AC VFD provides the lowest efficiency.
To continue with earlier message I have to add that a clear trend is emerging in today's major appliance industry for lower energy, high efficiency motors. Studies have shown that electronically driven motors, the majority of which will be of the BLDC type, will soon replace constant-speed single-phase induction motor and variable-speed universal motor drive designs.
It seems you have answered your question in regards to Efficiency. I would ask myself what is the exact load, is the motor continous, and what HP is required. As far as emissions, does an electric motor create them? Or are you more concerned about the power requirements?
Is this a single phase or three phase application?

I was expecting your reply to my recent posting quoted below:
Your earlier query was:
"Is it efficient to use a reluctance motor for household pumping purposes?"
Present query is on motor performance for 5HP,3Ph,1 hr continuous running.
It will be helpful if you can explain the purpose of study,so that more purposeful reply,specific to your need,can be given.
