Pin Configuration

17HS4401S NEMA 17 Stepper Motor Pinout and Connection Guide
The 17HS4401S NEMA 17 Stepper Motor has 4 pairs of wires, each pair consisting of a positive and negative wire, totaling 8 wires. These wires are connected to the motor's internal coils, which control the motor's rotation. Here's a breakdown of each pin:
Pinout:
1. A+ (Black wire): Positive wire of Coil A
2. A- (White wire): Negative wire of Coil A
3. B+ (Red wire): Positive wire of Coil B
4. B- (Yellow wire): Negative wire of Coil B
5. C+ (Blue wire): Positive wire of Coil C
6. C- (Green wire): Negative wire of Coil C
7. D+ (Orange wire): Positive wire of Coil D
8. D- (Purple wire): Negative wire of Coil D
Connection Structure:
To connect the motor to a driver or controller, follow this structure:
Coil A:
Connect A+ (Black wire) to the +A terminal on the driver or controller
Connect A- (White wire) to the -A terminal on the driver or controller
Coil B:
Connect B+ (Red wire) to the +B terminal on the driver or controller
Connect B- (Yellow wire) to the -B terminal on the driver or controller
Coil C:
Connect C+ (Blue wire) to the +C terminal on the driver or controller
Connect C- (Green wire) to the -C terminal on the driver or controller
Coil D:
Connect D+ (Orange wire) to the +D terminal on the driver or controller
Connect D- (Purple wire) to the -D terminal on the driver or controller
Important Notes:
Ensure the motor is connected to a suitable driver or controller that can handle the motor's current and voltage requirements.
Follow the driver or controller's datasheet for specific connection instructions, as pinouts may vary.
When connecting the motor to a driver or controller, make sure to match the coil connections correctly to avoid damage or incorrect motor operation.
If you're using a microcontroller or other control device to drive the motor, ensure you have the correct library or firmware to control the motor's movement.
Remember to handle the motor and its connections with care, as incorrect connections or handling can damage the motor or other components.
