Step 4: Connecting the Motor (continued)
Four Lead Motors
As shown in figure 5.7, a four lead motor can be connected to the SD17063 in only one way. Many four lead
motors, including AMCI’s SM42 motors, have eight wires inside the motor. These wires are connected in
series or parallel in the motor, and four leads are brought out to the drive.
Figure 5.7 Four Lead Motor Connection
Six Lead Motor
As shown in figure 5.8, a six lead motor can be connected to the SD17063 in two ways. A Series Connected
motor offers more torque than a Center Tap Connected motor at low speeds, but usually offers lower torque at
high speeds. However, the operating temperature of a center tap connected motor is always higher than a
series connected motor.
Note that the A CTAP and B CTAP pins on the motor connector are not powered and are for wiring convenience
only. A Center Tap Connection is equivalent to a unipolar connection because only half of the winding is used.
