Hello,
We have a high torque application i.e. we want to develop a motor control for 2Wheeler and 4Wheeler applications. And the task is to use FOC algorithm! Which is causing problem while startup.
Currently we are using F28069M with our custom inverter and sensing circuits. The motor is working fine with this setup for no load. But sometimes onload startup cause the motor to rotate in reverse direction.
I want to know that if I used absolute encoder to provide angular position of motor from start will it solve the problem?
The working will be as follows :
Start the motor by providing perfect switching sequence according to the rotor angle measured and hand over the control to FOC once higher speed where perfect back emf wave can be observed is attained.
Please help me with the example if anyone has done this before.
If there is another solution which don't use Hall sensors then please do recommend.
I have check lab Lab 21 – Initial Position Detection and High Frequency Injection but it seems that it is used for salient motor but ours is non-salient motor.
