Sensorless BLDC motor controller

Hi Mili,

What is the system voltage and motor current?
What algorithm do you intend to use?
Please see the selection guide here: www.ti.com/.../overview.html

Hello sir,thanks for your reply.
system voltage is 150-350 V DC
Motor current is 16 A(AC) max
Motor voltage is 90-180 V(AC)
We intend to use Field Oriented Control algorithm for our sensor less BLDC motor.

Thank you

Hello Sir,

please suggest me solution for above specifications.

Hi Mili,

Sorry for the delayed reply.

We do not have an IC that can control the device directly. For a general configuration of what is needed, please see www.ti.com/.../TMDSHVMTRPFCKIT

Hello sir,

Don't bother about Motor power ratings....

if you people provide FOC logic for any type of BLDC and AC three phase Induction motor.

we can upgrade it to higher power rating motors..

We are actually interested in software logic for FOC Algorithm by monitoring and taking feedback of Motor parameters

Please guide us to implement software logic of FOC by using Instaspin Series Controllers(Texas)..

we are at proto typing stage of our project.

If possible please arrange your technical person to visit our company at Pune branch office.

please reply as soon as possible....
