Four Lead Motor Connection
Six Lead Motors
Six lead motors can be connected in series or center tap. A series connected motor produces
more torque but it will not be able to run as fast as a motor in center tap configuration. In series
operation, the motor should be operated at 30% less than the rated current to prevent
overheating. Refer to the wiring diagrams below to connect a six lead motor.
