I am searching for controllers for PMS (permanent magnet synchronous) motor

Voltage up to 150V
Amperage up to 500A peak
with encoder feedback or with vector control algorithm

How about price ?
or price/preformance

I see that it is based on IGBT modules (400V). When driving 120V motor I could use MOSFET controller - less switching losses.

Not a huge amount.... IGBT's have come a long way. And the problem with your situation, is that between them and Kelly, they're the only ones that make a 120VDC BLDC motor controller that is commercially available. And I won't recommend Kelly.

Not sure about price, you should contact one of their distributors.

sevcon is a great company with good quality and the performance on the controllers I've seen is good. These are their new line.

Thanks for reply.
I will write inquiry to Sevcon.
Maybe someone else have found other manufacturer.
I have also found Sigmadrive controllers http://www.dmcde.de
But they limit max. to 120V battery supply

have you heard back from Sevcon??
and may be you can checkout Zapi's AC-5
they show maximum battery voltage of 152V

I'm just curious. - Where did you find that 75 KW PMS > - Gary B.

It is slightly overvoltaged perm motor. nominal voltage 96V.
Due different battery configuration the nominal voltage will be 115-120V.
Motor is rated at 16kW nominal S1, peak 2.2 x 16kW ~35kW

before buying a sevcon controller, u might consider my thread on ES
