Stepper Motor SY28STH45-0674B - NEMA 11 Hybrid Dual Shaft Stepper Motor
The Stepper motor SY28STH45-0674B is a compact and powerful 2-phase hybrid stepper motor in NEMA-11 size and is ideal for CNC machines, laser systems, positioning systems, measuring devices, precision engineering and automation applications. Thanks to its precise step control, the motor enables precise movements while running smoothly and with high repeatability. The motor shows its strengths particularly in applications with limited installation space. The size of 28 × 28 mm corresponds to NEMA 11.
The SY28STH45-0674B has one Step angle of 1.8° (200 steps per revolution) and ensures precise positioning with even power transmission. With one Motor length of 45 mm The motor is ideal for small to medium-sized drive tasks in compact CNC systems, positioning axes and precision mechanical applications.
The engine works with a Rated voltage of approximately 4.5 V and one Phase current of 0.67 A. The robust hybrid design ensures smooth running, a long service life and reliable continuous operation. The Double shaft (double-sided shaft) enables the use of additional components such as encoders, handwheels, couplings or sensors on the back of the motor.
Thanks to its compact size and precise control, the motor is ideal for applications with limited installation space and high requirements for positioning accuracy.
