Motor startup problem

I use FOC+Hall method and I have a problem with startup.When I start the motor, the motor has startup vibration.I try to adjust speed/IQ/ID Kp, Ki to make the startup stably.But it still has startup vibration.any suggestion for this kind of problem?T...

MTBF of L6472PD

Would you please offer me the Q&A report of L6472PD? I want to get the MTBF data of this IC.

I want to control position using STEVE-SPIN3204.

I want to control position using STEVE-SPIN3204.BLDC 24V motor and external encoder were used and it was set as position controller. I compiled and downloaded it, and when I start the motor, the motor vibrates.The way I know 1) motor start 2) Move th...

We are running into an L99MC6 caution (lowest caution on page 12 of Doc ID 16523 Rev 1) where our +13.8V supply is bleeding back through relay coils to source outputs and elevating the 3.3V Vcc supply before the charge pump seems to ramp up). Workarounds?

Our circuit uses an L99MC6 6-ch driver in 3-ch bridged mode to drive 3 relays (Song Chuan p/n 301-1A-C-R1-U03-12VDC) with a common +12V rail connected to the relays. The relays are activated by a sink output. The circuit's 3.3V logic Vcc is temporari...

I am using HCF4010YM013TR. There are two different power supplies described, Vdd and Vcc. 1) Data sheet does not seem to specify low side supply voltage 2) Is there any requirement as to when Vdd and Vcc should be applied and removed

Dear All, I've a problem with my step-down regulator L7985A. On power up, the DC / DC is activated when the ENABLE pin reaches about 880mV, while on the datashhet it is reported 1.2V as the ON threshold.

How to estimate current consumption of STGIPQ8C60T-HZ control electronics? i mean pins VCCU, VCCV, VCCW? My PWM frequency will be at 20kHz.

92E540

I want to search datasheet about '92E540'. But I couldn't found that. Can I get the datasheet about IC '92E540'?

STSPIN32F0 12v internal regulator problem

Hi,I designed BLDC motor driver 12v powered card with the STSPIN32F0 chip and developed my own software. My codes run smoothly on the STEVAL-SPIN3201 kit.But on the own my card, 12v regulator outpus voltage inside chip didn't rised more than 1v.When ...
