Hi, I want to control my 6-poles(3 pole pairs) BLDC motor using MTRCKTSBNZVM128 SW(BLDC sensorless 6-step app).
MOTOR SPEC : 50W, 6-poles, 9 slots
The problem is that we want to control our motor to maximum upper 6000rpm, but it just rotating 3100rpm now.
I checked the MCU(S12ZVML128) using maximum voltage duty(95%) but the current(max 3.2A) is too low for maximum rpm. So we estimate the current is the main point of this situation.
I understand that this app SW is designed for EVB board and motor, so it's not optimized for our application now.
Then How can I bring more current for ours? or Do you have any other point of view to solve our problem?
Please give me your opinions.
