Figure 6: Single-wye connectionsfor a brushless DC motor.
Figure 6 is a schematic representation of the windings of the
Brushless DC motor. The connection shown in the drawing is a
single-wye. There are three other ways the motor windings can be
connected which will change the speed and horsepower (the torque
remains constant in any given motor as the connections are changed)
but these other connections are not made for different voltages as is
the case with the AC induction motor. The standard connection
conventions of the AC motor are followed in the assignment of

connections see the POWERTEC Motor Manual.
