Product Description:
Sanyo Denki manufactures the 103H8581-6020 is a 5-phase stepping motor that is used for high-accuracy motion control. It features a dual-axis configuration with a holding torque of 2.06 N·m or more. The motor is well known for its high degree of experience in motor technology and industrial automation products.
The 103H8581-6020 stepping motor consumes a rated current of 0.75 A per phase and has a wiring resistance of 5.7 Ω per phase with inductance of 25 mH per phase. It features a rotor inertia of 1.45 × 10⁻⁴ kg·m² and weighs 1.5 kg. The precision mechanical parameters, such as shaft diameter, keyway width, and mounting size, ensure compatibility with any set of mechanical systems. The motor also has a double shaft, with each 12 mm with a tolerance and approximately 25 mm in length. The motor features a parallel key of 4 × 4 × 25 mm for strong shaft coupling. The wire is UL1430 AWG22, of 62.15 ± 0.8 mm length, and vinyl tube length 28 ± 1 mm. The minimum length of the motor is 305 mm, with an earth terminal of M4 × 0.7 × 6L screw hole. The electrical parameters offer steady current and resistance values that ensure steady performance.
This motor is specifically suited for use in systems where steady torque and accurate positioning are required. Motor diameter is 60 mm with tolerance and is mounted on an 85 × 85 mm square face having four mounting holes of 5.5 mm diameter, center-to-center spaced at 70 mm. The two-axis 5-phase excitation enhances the stability of torque and offers smooth operation. The 103H8581-6020 motor features the parallel key on the shaft, which facilitates safe mechanical coupling for maintaining alignment and torque transfer.
