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

[roberto_foelix]

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.
