ACIM Constant Parameter Model VI

Owning Palette: AC Induction Motor VIs

Requires: Electric Motor Simulation Toolkit

Simulates the AC Induction Motor (ACIM) by using the constant parameter model function.

Example

	temperature specifies the stator temperature and the rotor temperature of the electric motor. If the value of stator temperature or rotor temperature is greater than 0, this VI performs the temperature correction functionality for the stator resistance and the rotor resistance. stator temperature specifies the temperature, in kelvins, of the motor stator. The default value is 0. rotor temperature specifies the temperature, in kelvins, of the motor rotor. The default value is 0.
	initialize? specifies whether to initialize the internal state of the electric motor. This VI performs calculations that are dependent on all previous data since the VI last ran or since you set initialize? to TRUE. If you set initialize? to TRUE, this VI resets the internal state of the motor to 0 and restarts the electric motor simulation. The default value is FALSE.
	ACIM constant parameters specifies the parameters describing the characteristics of an ACIM. number of poles specifies the number of poles in the electric motor. The number of poles must be an even number. stator leakage inductance specifies the leakage inductance, in henries, of the stator windings. The value of stator leakage inductance must be greater than 0. rotor leakage inductance specifies the leakage inductance, in henries, of the rotor windings. The value of rotor leakage inductance must be greater than 0. magnetizing inductance specifies the magnetizing inductance, in henries, of the motor. The value of magnetizing inductance must be greater than 0. stator resistance specifies the resistance, in ohms, of the stator windings. The value of stator resistance must be greater than 0. rotor resistance specifies the resistance, in ohms, of the rotor windings. The value of rotor resistance must be greater than 0. base temperature specifies the base temperature, in kelvins, for the stator resistance and the rotor resistance. The value of base temperature must be equal to or greater than 0. stator temperature coefficient specifies the coefficient, in K^-1, for temperature correction of the stator resistance. rotor temperature coefficient specifies the coefficient, in K^-1, for temperature correction of the rotor resistance.
	voltage specifies the three-phase voltage, in volts, of the electric motor. The voltage represents the three-phase voltage in a three-phase electric power system. Therefore, this array must have three elements, and each array element must specify one phase of the voltage.
	speed specifies the rotor speed, in revolutions per minute, of the electric motor.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	dt specifies the time interval, in seconds, at which LabVIEW simulates the electric motor. The value of dt must be greater than 0.
	abc current returns the three-phase current, in amperes, in the electric motor. This output is a three-element array, each element representing one phase of the three-phase current.
	torque returns the electromagnetic torque, in newton meters, of the electric motor.
	error out contains error information. This output provides standard error out functionality.
