Details  Examples

Create PMSM Variable Parameter Model (RTT File)

Reads the RTT file to get a LabVIEW class reference of PMSM variable parameter model.

	RTT file specifies the path to an RTT file. The RTT file contains motor parameters and data that the JMAG-RT software generates.
	table size specifies the number of rows and columns in a two-dimensional table. By default, the table has the same number of rows and columns. The value of table size must be greater than 0.
	temperature correction parameters specifies the characteristics of the electric motor for temperature correction. If the value of any temperature correction parameter is not a number (NaN), this VI reads the temperature correction parameter from the RTT file. coil base temperature specifies the base temperature, in kelvins, of the motor coil. The value of coil base temperature must be equal to or greater than 0. The default is NaN. coil temperature coefficient specifies the coefficient, in K^-1, for temperature correction of the motor resistance. The material of the coil determines the value of coil temperature coefficient. The default is NaN. magnet base temperature specifies the base temperature, in kelvins, of the motor magnet. The value of magnet base temperature must be equal to or greater than 0. The default is NaN. magnet temperature coefficient specifies the coefficient, in K^-1, for temperature correction of the magnet flux. The material of the magnet determines the value of magnet temperature coefficient. The default is NaN.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	PMSM variable parameter model returns and saves the parameters and data of the PMSM in a LabVIEW class. You can use this LabVIEW class object as the input to the PMSM Variable Parameter VI and the Generate PMSM Variable Parameter Model FPGA Data VI.
	PMSM type returns the connection type and the number of poles of the electric motor. connection type returns how the permanent magnet synchronous motor is connected to the circuit. Currently, the Electric Motor Simulation Toolkit only supports the star connection. If the RTT file uses delta connection, LabVIEW returns error code -376401. 0 Star—Returns the connection type as star connection. High voltage transmission systems typically use star connections. Star connections offer the advantage of providing multiple voltages. 1 Delta—Returns the connection type as delta connection. Low voltage distribution systems typically use delta connections. Delta connections offer the advantage of high reliability. number of poles returns the number of poles in the electric motor.
	error out contains error information. This output provides standard error out functionality.

The default is NaN. coil temperature coefficient specifies the coefficient, in K^-1, for temperature correction of the motor resistance. The material of the coil determines the value of coil temperature coefficient. The default is NaN. magnet base temperature specifies the base temperature, in kelvins, of the motor magnet.
