Max Current flow through the motor - sensored FOC of PMSM

DIJO PAULSON
Intellectual 710 points

Hi,

I am using TMDSHVMTRPFCKIT with 200V, 200Hz PMSM, 8 pole, 1.27 Nm

In the sample code the base quantities are defined as

#define BASE_VOLTAGE 236.140                      // Base peak phase voltage (volt)

#define BASE_CURRENT 10                              // Base peak phase current (amp)

#define BASE_FREQ 100                                    // Base electrical frequency (Hz)

1) The phase current readings clark.As, clark.Bs, clark.Cs are shown in the graph in pu scale w.r.t 10 A right?

My motor is rated for 2.8 Arms. By this I assume that the motor is capable of drawing this much current at full load.

2) What is the amount of current flowing through the motor when Iq=1.0 pu?

3) At what value of current the PWMs will trip ?

Regards,

Dijo Paulson
