permanent magnet synchronous motor

[Rihab Abdelmoula]

Hello

I want to know if it exists  permanent magnet synchronous motor which feded by a alternative current in the list of motor given by advisor.

thank you

Hello Rihab,

The ADVISOR models of the motor/controller systems do not have anything specific to motor type in the models themselves: the electrical side is modeled with simple power flow (with some consideration of bus voltage) and the output of the motor is torque and shaft speed to add to the driveline. Thus, the only thing that is indicative of the type of motor is the efficiency map and peak torque by shaft speed performance data. Note that these data files represent the integrated motor + power electronics (controller).

You can check the details of the types of motors each file was based on by looking at the header of each data file:

https://sourceforge.net/p/adv-vehicle-sim/code/HEAD/tree/application/branches/advisor/data/motor/

The files that begin with "MC_PM..." are permanent magnet motors.

Hope that helps.

Michael

Hello Micheal 
thank you for your reponse. I have already understood what you illustrate . 

When i choose the type of motor for exemple MC_PM32evs and MC_PM32ev , i find in principle window of matlab 

Data loaded: MC_PM32evs - Auxilec Thomson 32 kW (continuous), permanent magnet motor/controller

Data loaded: MC_PM32ev - Unique Mobility 32-kW continuous, 53-kW intermittent permanent magnet motor/controller

what is the different bitwen this 2 motor ?

and how can i modify motor max power ? it is just by modify it in the gui windows ?

and finilly how can i modify mc_map_spd and mc_map_trq , So the torque map in the gui window? 

thank you

The only information on the differences between data files is contained in the header of the data file (and in the data themselves) so I direct you there.

You can modify the max torque using the mc_trq_scale (I believe -- look at the center bottom of the vehicle input screen under the parameters for motor/controller; there may also be some parameters to the right of the motor when you load it). If you want to change the actual shape of the data, I recommend taking a motor data file (MC_PC**.m) and save it under a new name and actually modify the data to be to your liking.

Hope that helps

Dear Mr.Micheal

thank you for your explication. I am trying to understand the motor MFILE. I understand the principle of calculated, except coeifficients used to multiply the torque values. for exemple for MC_AC75

Mc_map_trq = [- 200 -180 -160 -140 -120 -100 -80 -60 -40 -20 0 20 40 60 80 100 120 140 160 180 200] * 4.448 / 3.281;

what is this coeifficient "4.448 / 3.281 " 

It is not the same for different motor

thank you 

[Michael P O'Keefe]

The factor 4.448 / 3.281 is to convert from ft-lbs to N-m; probably the original data specification sheet was in ft-lbs-force.

hello Mr Michael 

Thank you for your explication.

i'm training to calculate efficiency map of my own pmsm.

eff=Pin/Pout

Pout=T*w

Pin=Pout+iron losses+copper losses+mechanical losses

i'm using the formula to calculate efficiency for different values of T and w 

i'm find eff > 0.9 in all case , it is normal ?

Can you help me with any other information !

 thank you

Rihab

Efficiency of the motor can be quite high and over 90%. You can do some google searching to check. There are some nice reports from Oak Ridge National Lab on the Prius, for example. Be sure to take into account the power electronics, though.
