Product Description:
The 103H7853-7055 StepSyn Stepping Motor is manufactured by Sanyo Denki for precise motion control. It transforms electrical pulses into fixed mechanical steps which are vital in automation and robotics systems. This model supports fine motion adjustments and repeatable positioning accuracy in critical applications.
The 103H7853-7055 stepper motor operates with a basic step angle of 0.72°which allows fine motion control for high resolution applications. Its maximum holding torque is 1.86 N·m while under 2-phase energization it consistently maintains a torque of 1.37 N·m. This level of torque is suitable for maintaining position even under moderate loads. The motor rated current per phase is 0.75 A which directly impacts torque performance and thermal behavior. The motor rotor inertia of this model is 0.84 × 10⁻⁴ kg·m² which enables controlled acceleration and deceleration particularly in load sensitive mechanisms. The 103H7853-7055 stepper motor has a compact length of 43.5 mm allows it to be installed in limited space designs. It fits into the NEMA23 standard with a 60 mm square frame and a 47.14 mm mounting pitch that provides broad compatibility with pre existing motor mounts and fixtures. The motor mass is 1.36 kg which supports stable placement and vibration control during operation.
The 103H7853-7055 stepper motor winding resistance is 1.27 Ω per phase and the winding inductance is 3.3 mH per phase. The motor has a resistance of 5.5 Ω and an inductance of 15 mH per phase relevant when the winding layout or driver compatibility is analyzed. The insulation class of this motor is classified as Class B for thermal endurance which ensures stable insulation under continuous thermal cycling conditions. It supports operation in ambient temperatures ranging from -10˚C to +50˚C without performance loss.
