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

Question asked by Roberto Foelix on Sep 26, 2018
Latest reply on Sep 26, 2018 by xiangjun.rong

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

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.
