gwhy! said:on a side note of delta/wye configs, I modded one of my cheapo motors and yes it did reduce the speed and increased the torque but ( for reasons i didnt bother investigating due to my gearing is ok in delta ) ran hotter under load.
If this was on the motor fitted with sensors, the reason is simple. Timing needs to be shifted by +-30deg, as the field will either lag or lead by 30deg of how it was previously.
30deg timing advance = a hell of a lot more current and heat!
