ACIM Motor identify without blocking (KMS & HVP-MC3PH)

roberto_foelix — Wed, 26 Sep 2018 09:11:13 GMT

I have a closed vibration motor with the following information:
2 pole ACI-Motor
Rated voltage 230VAC
Rated current 2.7A
Nominal frequency 200Hz
Centrifugal force 4.517N

I am unable to block the motor to determine the engine parameters with the Kinetis Motor Suite and HV-Kit.
How can I determine the parameters?

My test facility:

HVP-MC3PH-Kit (High-Voltage Development Platform|NXP ) & HVP-KV46F150M

Kinetis Motor Suite (KMS)

I did the following measurement with a test motor (3GAA071312-ASE) and the vibration motor.

Once with a frequency converter (Invertek P2) and once with the HV kit & KMS.

	Test-Motor		Vibration-Motor
Motor Pole	2		2
Motor Rated Voltage	230 V		230 V
Motor Rated Power	0.55 kW
Motor Rated Current	2.2 A		2.7 A
Motor Rated Speed	2790 rpm		12000 rpm
Motor Centrifugal force	1.88 Nm		4.517 Nm
	FU (Invertek P2)	NXP-KMS (HVP)	FU (Invertek P2)	NXP-KMS (HVP)
Effective Switching Frequency	16 kHz	? kHz	16 kHz	? kHz
	FU (Invertek P2)	NXP-KMS (HVP)	FU (Invertek P2)	NXP-KMS (HVP)
Motor Stator Resistance (Rs)	8.459 Ohm	3.705 Ohm	11.238 Ohm	? Ohm
Motor Rotor Resistance (Rr)	5.071 Ohm	3.847 Ohm	6.738 Ohm	? Ohm
Motor Stator Inductance (Id)	0.3177 H	0.3725 H	0.0763 H	? H
Mutual Inductance		0.3570 H		? H
Motor Magnetising Current	1.2 A		1.1 A
Motor Leakage Coefficient	0.114		0.096

Thank you for your support

Hi, Roberto,

We have an application note AN4642.pdf, which focuses on the PMSM, as you know that the ACIM parameters measurement is more complicated than PMSM. Generally, you can measure the rotor parameters of ACIM with the

rotor blocked and non-load methods.

I do not think we have application note for ACIM parameters measurement, anyway, you can submit a question on the "motor control and smart Energy" forum so that the expert on motor control can answer you. BTW, I do not know whether MCAT tools can support ACIM.
