Product Description:
The 103H7123-0740 motor , which belongs to Sanyo Denki’s StepSyn Stepping Motors series, has a holding torque of 0.83 Nm that guarantees high positioning accuracy. The motor’s winding resistance is set to 0.6 Ω per phase, which greatly reduces energy loss. The drive has a per phase inductance of 0.8 mH which smooths current flow and therefore greatly increases performance.
It has a source voltage of 24 DCV and thus requires a stable and reliable low-voltage. This motor has a current of 2 A per phase, which provides ample energy for each winding during stepping and ensures smooth operations. Its inertia of the rotor is 0.21×10⁻⁴ kg·m² that allows the design to step quickly and precisely. Its total weight is 0.65 kg. With a dimensional length of 56 mm square, it can be easily integrated into systems with restricted designs. This stepping motor guarantees a finer range of control at a 1.8° stepping angle. This model, along with 2 phase stepping technology, allows for steady and smooth operations.
The Sanyo Denki made 103H7123-0740 variant has been augmented with advanced features that improve its overall performance. Its continuous microstepping feature allows control of the motor and its motion with up to 1/16 microstep resolution, resulting in smooth motion and precise positioning. Because the motor unit is rated for a 100% continuous duty cycle. Keeping the noise level of the work environment lower, this unit operates at 55 dB. Additionally, it is provided with a flange-mounted configuration and allows easy installation in different types of mechanical systems.
