STEP MOTOR CONFIGURATIONS
Step motors can be configured as 4, 6, or 8 leads. Each configuration requires different currents. Shown below are different lead configurations and the procedures to determine their output current.
6 Lead Motors
When configuring a 6 lead motor in a
When configuring the motor in a series configuration (connected from end to end with the center tap floating) multiply the per Phase (or unipolar) current rating by 0.7.Use this result to determine the current adjustment resistor value.
WARNING! Step motors will run hot even when configured correctly, damage may occur to the motor if a higher than specified current is used. Most specified motor currents are maximum values. Care should be taken to not exceed these ratings.
4 Lead Motors
Use the specified series motor current to determine the current adjustment resistor value. Four Lead Motors are usually rated with their appropriate series current, as opposed to the Phase Current which is the rating for 6 and 8 lead motors.
8 Lead Motors
Series Connection: When configuring the motor windings in series, multiply the per Phase (or unipolar) current rating by 0.7. Use this result to determine the current adjustment resistor value.
Parallel Connection: When configuring the motor windings in parallel, multiply the per Phase (or unipolar) current rating by 1.4. Use this result to determine the current adjustment resistor value.
NOTE: After the current has been determined, according to the motor connections above, follow the procedure Determining Output Current above to find the current value. Then use Table 3 to choose the proper resistor value.
