Product Description:
The 103H7851-7051 Stepper Motor made by Sanyo Denki is a precision electromechanical device that converts electrical pulses into discrete mechanical movements. Its features such as holding torque, phase current and rotational accuracy are widely used in robotics, Industrial automation and CNC machinery.
The 103H7851-7051 stepper motor each phase consumed a current of 0.75 amperes which determined power consumption and heating. It generates higher torque with this higher current but also produces more heat. The voltage that it requires is 100 volts AC which ensures compatibility with power sources, and it needs an integrated driver or controller to handle the AC to DC conversion. It also comes with a self switch Setting which is used for controlling speed or phase switching. Its dielectric strength is 1120 VAC for 1 minute which determines insulation quality between the motor windings and frame. This feature helps it prevent electrical failures due to insulation breakdown and ensures safe operation under high voltages. Its length is 66 mm which describes its physical dimension and helps in fitting into a mechanical design. It precisely positions itself with positional accuracy tolerance value of ±0.054° which means high accuracy, useful for CNC, 3D printers and robotics.
The 103H7851-7051 stepper motor is able to reduce step errors and improves precision in movement. The maximum allowable temperature for its insulation is 130°C. This means it can sustain operation up to 130°C before insulation degrades which is important for high duty cycle applications. The highest step rate at which the motor can operate without additional inertia is 100 Hz which helps in determining speed capability. The maximum torque it can output before losing steps is 1-5.0 which is dependent on frequency and drive settings.
