The higher torque configuration or full coil uses the full windings of the phases Half Coil Configurations As previously stated the half coil configuration uses 50 of the motor phase windings This gives lower inductance hence lower torque output Like the parallel connection of 8 lead motor the torque output will be more stable at higher speeds This configuration is also referred to as half choppe...
