Product Description:
The Sanyo Denki 103H7126-0722 Stepping Motor is part of the StepSyn Stepping Motors series. The stepping motor is efficient and reliable that makes it ideal for industrial automation processes.
The 103H7126-0722 Stepping Motor comes with a shaft which has a round cross section which is suitable for simple couplings without keyways or flats. It is reliable in moderately humid environments but condensation must be avoided to prevent internal damage or insulation failure. It uses a unipolar configuration which means each coil has a center tap that allows simpler driving circuits but may reduce torque compared to bipolar. It rotates 1.8° per step which equates to 200 full steps per revolution which is a common value for precision positioning. The module winding is designed to handle 3 amperes of current for optimal torque without overheating. It weighs around 0.98 kg which has effects on the system load and mounting requirements. It comes in a length of 75.8 mm which indicates a medium body size that can accommodate moderate torque. All of its electrical connections are made via lead wires which offers flexibility in wiring but requires manual termination.
The 103H7126-0722 stepping motor can maintain a fixed position under a load of up to 1.27 Newton meters when powered. It comes with 0.36×10⁻⁴ kg·m² of rotor inertia which means it accelerates and decelerates quickly. It can function safely in ambient temperatures between -10°C and +50°C which is suitable for typical industrial and lab environments. It has only one output shaft which is common for applications that require drive on only one end. This highly efficient stepping motor is widely available in wake industrial stores.
