Can EV PMSM Motor controller be used as inverter to run appliances.
EV pmsm controller runs at different frequency, if frequency is fixed at 50Hz .Can it be possible?

i am thinking of using proper step up transformer to reach voltage at 415V RMS.

 

I've worked on systems that have utilized induction motor VFDs driven into step up/dwn transformers for alternate voltage motors.

EV PMSM motor controller are basically inverter that can generate frequency like 0-300hz(example.), that frequency change cause speed variation..... i was looking at a way to use that controller at fixed 50hz to work as a home inverter

 

Aren't those PMSM motors 3 phase? Is the item you want to power 3 phase?

Yes I want to run three phase load through that PMSM motor controller. As a industrial use..not as a home inverter.... I will modify my starting thread..

Unless it's a very simple VF motor controller, it's unlikely to work or be stable. While the basic AC inverter circuit might be very similar, a motor controller usually relies on some sort of feedback from an actual spinning motor as a control function for a speed/torque set-point. A home power inverter feedback set-point is the utility frequency/voltage that's usually independent of the type of load.

I looked over a PMSM ev .motor controller ... By pressing lever ...frequency might be changing ... To achieve frequency ... Well feedback must be there but I am not sure... Controller output is sinusoidal and it is using space vector control to achieve sin wave... If it's simple v/f controll then voltage must be dropping with frequency to achieve low speed .... And but I am not sure that... it's just inverter with V/F control
