Hi, I'm new to iMotion and have trouble running small bldc which is for hdd spindle with recently bought EVAL-IMM101T-046
I've measured and configured parameter with MCEWizard, but the wizard complains that it can not set low back emf constant.
I thought IMM100 is supposed to be used for small bldc, am I doing something wrong?
Below is measured parameters
I would definitely be appreciated for any help, thank you.
Nidec 275F-42MY-01
Rated Amps = 0.6 A
Motor Poles = 12
Stator Resistance = 2.975 ohms / phase
Inductance = 0.3822 mH / phase
Back emf constant = 0.280V / 7.5Hz * 3 * 3.4 = 0.3808V
