Product Description:
The 103H548-0411 Stepper Motor is the product of Sanyo Denki and it is part of the StepSyn Stepping Motors series. It operates in an open loop control and uses encoder to constantly adjust position that leads to higher accuracy.
The 103H548-0411 stepper motor insulation resistance is 100MΩ which indicates the electrical insulation quality. This module has a high positional accuracy as its standing angle error is ±0.09 which is due to mechanical and electrical tolerances. This model shows no abnormality when applying 50/60Hz AC voltage which means it can withstand high voltage without insulation failure, which is important for durability and safety. It has a lower radial play value of 0.025mm (0.001 inch) MAX Load 4.4N (1lb) which indicates a more precise and stable shaft and reduces mechanical noise and increasing accuracy. Its internal temperature can rise up to 80K from ambient temperature during operation which may affect the lifespan. This module has 0.075mm MAX Load 4.4N axial which refers to shaft movement along the axis. This motor comes in the size of 42 mm which helps in compatibility for mounting and integration into systems. The ambient temperature and humidity ranges for this motor is -10˚C~+50˚C and 20~90% RH (no condensation) respectively which defines the working conditions for the motor to ensure reliable performance in standard industrial environments.
The 103H548-0411 stepper motor is categorized in the insulation class of B which defines the maximum allowable temperature for the motor windings. The servo motor deviates only 0.025mm from a perfect rotation which is important precision control. Its operating voltage is 100 V AC which suggests it is made for medium power industrial automation applications.
