Product Description:
The 103H548-0440 is a stepping motor from Okuma Automation that is characterized by high torque supply and low inertial during operation. This motor operates in precise step increments and is perfect for applications where extremely precise positioning is needed. Typical applications suited to this type of motor design include CNC control units, 3D printing machines and robotic production applications. The 103H548-0440 motor offers two-phase operation at an average stop angle of about 1.8 degrees. The output shaft of this motor unit is also equipped with a metallic shaft that operates on a single axis and can typically support high industrial loads. The current consumed by this motor unit for each of its operation phases is estimated to be about 1.4 amperes, and its holding torque is also about 0.72 newton meters.
The 103H548-0440 industrial motor unit is classified under Nema 17, with a frame size of about 42 millimeters and a shaft diameter estimated to be about 5 millimeters. The wiring required by this motor for connection is a 6-lead wire, which is readily available from Okuma. The detent torque produced by this motor is estimated to be about 0.029. Customers operating in extremely cold regions can purchase this product for their industrial operation without the fear of sudden machine failure. The minimum ambient temperature recommended for this motor unit is about 0 degrees Celsius.
The 103H548-0440 motor unit produces very little vibration during operation; also its housing protects it from large foreign solids. However, this motor is still designed for indoor operations and should be shielded from extreme operation conditions. The maximum recommended ambient temperature for this motor unit is about 1000 meters above sea level.
