0 100 % Nominal Inductance
The PM Motor Lq Flux Saturation attribute is an array of floating point values
that specify the amount of q-axis flux saturation in the motor as a function of
current. The units for q-axis flux saturation values are percent of Nominal
Inductance, such that a value of 100% means no saturation, and 90% means the
inductance is 90% of its value at zero current given by the PM Motor Lq
Inductance attribute.
The first array entry specifies the flux saturation value at 25% of the Continuous
Current Rating; the second entry specifies the value at 50%, and so on up to the
last entry, which specifies the value at 200% of the Peak Current Rating. (At zero
current, the motor is assumed to have no saturation, for example, an implied value
of 100%.)
PM Motor Ld Flux Saturation
Usage Access Data Type Default Min Max Semantics of Values
Optional
(IPM Only)
Set REAL 100
DB
0 100 % Nominal Inductance
The PM Motor Lq Flux Saturation attribute is an array of floating point values
that specify the amount of d-axis flux saturation in the motor at rated current. The
units for d-axis flux saturation values are percent of Nominal Inductance, such
that a value of 100% means no saturation, and 90% means the inductance is 90%
of its value at zero current given by the PM Motor Ld Inductance attribute.
The PM Motor Ld Flux Saturation value specifies the d-axis saturation at 100% of
the Continuous Current Rating.
PM Motor Extended Speed Permissive
Usage Access Data Type Default Min Max Semantics of Values
Optional - PVT
(PM Only)
Set/SSV USINT 0 0 1 Enumeration:
0 = False
1 = True
The PM Motor Extended Speed Permissive attribute value determines whether
the speed of a PM motor is allowed to exceed the Bus Overvoltage Speed. Setting
this value to True removes velocity limit protection against Bus Overvoltage
conditions associated with Rotary and Linear PM motors. In this case it is critical
