Connecting the Motor
Never connect or disconnect the motor while the power is on.
Four lead motors can only be connected one way. Please follow the sketch at the right.
Six lead motors can be connected in series or center tap. In series mode, motors pro-
duce more torque at low speeds, but cannot run as fast as in the center tap configura-
tion. In series operation, the motor should be operated at 30% less than the rated cur-
rent to prevent overheating. Winding diagrams for both connection methods are shown
below. NC means not connected.
Eight lead motors can also be connected in two ways: series and parallel. As with six lead motors, series operation gives you less
torque at high speeds, but may result in lower motor losses and less heating. In series operation, the motor should be operated
at 30% less than the unipolar rated current. The motors recommended in this manual should be connected in parallel. The wiring
diagrams for eight lead motors are shown below.
