Product Description:

The 103H7126-5040 is a highly accurate StepSyn stepping motor. The motor works effectively with industrial automation and textile machinery. Sanyo Denki designed the motor to enable stable motion control in challenging operations such as 3D printing and additive manufacturing.

The 103H7126-5040 stepping motor has a holding torque of 1.27 N·m when powered by two phases, which makes sure that the load can be handled steadily while it is working. The motor features a wire resistance of 1.05Ω per phase, contributing to its exceptional electrical performance. With a rotor inertia of 0.36 × 10⁴ kg·m², the motor shows a satisfactory equilibrium between load stability and responsiveness, thereby guaranteeing the highest possible performance within the given parameters. The motor is compact and easy to handle, weighing only 0.98 kg, thus, it may be simply fitted into mechanical systems. The stepping motor works with many different types of drives, which lets it do high-resolution microstepping, which improves positioning accuracy and makes motion changes smooth. The motor has advanced control options that ensure accuracy in situations where precise movement changes are needed.

The motor is made for uses that need steady power and precise motion control. Stepper motor controls work perfectly with the 103H7126-5040 stepsyn stepping motor, improving its performance by precisely controlling the current and arranging the steps optimally. Stepper motor drivers that support microstepping and advanced drive technologies make sure that the positioning is correct. Because it works with RTA and third-party controls, it can be used with more automation systems. Controlled torque, optimized rotor inertia, and the ability to take microsteps make it ideal for uses that need precise movement.
