Product Description:
The 03H7128-1451 is a DC hybrid step motor produced by Sanyo Denki. It is a part of the StepSyn stepping motors and is one of its two-phase bipolar stepper motors for movement control. It delivers high torque at low speed and can hold a position firmly even when not moving which is useful in pick-and-place and robotic arms systems.
The 03H7128-1451 hybrid stepping motor has a length of 75.8mm and 0.68 kg mass. The black-coated outer casing receives IP43 ratings which signifies protection against dust and water spray occurring at certain angles thus it operates best when located in dry conditions. The 03H7128 hybrid stepping motor provides operational standards of humidity level between 0.2 to 0.9 relative units, positioned beneath the 1000 m elevation mark and within the temperature of 32°F to 113°F. When operating beyond this specified range of parameters the motor experiences decreased efficiency and performance. It performs two hundred steps when rotating a full 360° at each step angle of 1.8°. The 03H7128 hybrid stepping motor enables exact match movement for scenarios that need regulated rotational motions and it requires a 3.35A DC current with a necessary 24V DC power source. The 03H7128 hybrid stepping motor uses standard 5V logic to get latched with Arduino systems and identical platforms.
The 03H7128-1451 hybrid stepping motor is designed to facilitate motion control system by integration with either microcontrollers or stepper drivers. It includes a shaft design that enables direct coupling because of its smooth shape. The 03H7128 hybrid stepping motor has 56mm x 56mm frame size and generates a peak torque of 0.88 Nm. It is available on Wake Industrial with one year warranty and worldwide delivery.
Frequently Asked Questions about 103H7128-1451:
Q: Why is a smooth shaft design used in the 03H7128-1451 motor?
A: The smooth shaft supports direct coupling, minimizing backlash in mechanical connections. This enhances positioning accuracy in precision systems.
Q: What advantage does a bipolar two-phase setup offer in the 03H7128-1451?
A: It provides better torque performance and smoother operation at low speeds. This setup also improves current efficiency through alternating magnetic fields.
Q: Can the 03H7128-1451 handle continuous high-speed operation?
A: It is optimized for low to medium-speed operations where torque retention is critical. Running at high speeds for extended periods may reduce positional accuracy.
Q: How does the 3.35A current rating affect performance in the 03H7128-1451?
A: A higher current allows the motor to deliver stronger magnetic fields and higher torque. It also enables better responsiveness in dynamic load conditions.
Q: Why is 24V DC input preferred for the 03H7128-1451 motor system?
A: 24V DC ensures a balance between responsiveness and thermal stability. It supports quick stepping without significant voltage drops.
