Product Description:

The 103H7124-0740 is a StepSyn stepping motor for industrial robotics that moves things precisely and with great control. The motor, which is made by Sanyo Denki, is to work efficiently and reliably. It works more easily and with less noise and vibration than regular stepper motors.

The 103H7124-0740 stepping motor works at 2A per phase, which makes sure that the power supply is controlled. The 0.74Ω phase resistance allows for easy current regulation, enhancing motor performance. The 1.4 mH phase inductance keeps everything stable by preventing the current from shifting. The motor's structure is designed to maintain step precision, reducing positional errors. The design reduces power ripple, which makes the system more stable in use. Adding a motor that reduces vibration makes the changes between steps smoother. Long-term performance reliability is supported by the internal construction, which is very important for demanding uses. The stepper motor is made for devices that need to be precise and consistent. The improved step-fractioning makes sure precise microstepping, which boosts control and lowers noise. The motor structure is made to run consistently, so it keeps working well even after a long time of use. The optimized winding design keeps the temperature stable, which keeps the motor from getting too hot.

The 103H7124-0740 stepping motor has a strong rotor design that makes it more reliable mechanically. The design makes sure that the system is stable and that there are few problems when it changes speeds. The rotor's inertia of 0.245 ×10⁴ kg·m² makes sure it rotates steadily, which is useful for tasks that need to be placed precisely. For smoother motion control, the motor has improved step-fractioning that lowers stepper resonance. The motor's improved motion control helps lower stepper resonance, which makes the system work more efficiently.
