Product Description:

The 103H7523-7051 stepping motor is a high-torque motor. It is made for position control in small systems. It works on a 2.8 A per phase current rating. Moreover, it gives high torque output and quick response in heavy-duty step-oriented tasks. It comes with four lead wires for use in bipolar drive configurations. These are common in industrial and embedded motion control designs.

This motor is given with a rotor inertia of 120 g·cm² to support rapid acceleration and deceleration but still deliver smooth running. It also features a detent torque of 0.025 N·m. This gives steady holding torque even when the motor is de-energized, improving positional stability and reducing mechanical drift. All stages consist of 0.95 Ω resistance and 2.7 mH inductance, offering the optimal electrical performance with stable thermal characteristics and highest power consumption efficiency. Moreover, this motor has a shaft diameter of 5 mm. It can also be connected to pulleys, gears, and couplers in different setups. The physical dimensions of this unit make it useful in printing, robotics, drives, and other tasks. Here, accuracy, repeatability, and compactness are the main needs. Further, step accuracy is ensured by the repeatability of step accuracy. The physical ruggedness of this motor will permit frequent stop-start operation without compromising performance. It is intended for long-term reliable performance, with electrical specifications ensuring smooth interfacing with standard stepper drivers.

The 103H7523-7051 offers a good compromise between size, torque, and responsiveness. It is used in either high-precision linear control or rotation indexing. It delivers good motion performance in small packages. Its rugged construction and reliability in use make it a good option for applications where there is a need for dependable stepping function in light or small systems.
