Flange size: 56 mm Motor length (motor only): 41.8, 53.8, 75.8, 85.8 mm Unipolar winding / Bipolar winding Single shaft / Dual shaft Stepping motors / Geared / With electromagnetic brake / With encoder High torque Low noise Energy-saving Compared to our conventional model, torque performance has improved by approximately 40%.* This contributes to shortening the positioning time and machine cycle time. These motors have noise levels approximately 3 dB lower than the current model, reducing the noise level of machines.* Motor efficiency has been improved by approximately 3% compared to the current model.* This contributes to reducing power consumption of machines and the motor’s heat dissipation. * A comparison between our current model 103H7123-5840 and new model SM2562C30B41.
