Questo ibrido motore passo-passo ha un angolo di passo 1,8 ° (200 passi / giro). Ogni fase disegna 1,2 A a 4 V, consentendo una coppia di 3,2 kg-cm (44 OZ-in) possesso. Il motore ha sei fili coloratiterminati con conduttori nudi che gli consentono di essere controllato da entrambi i driver del motore passo-passo unipolari e bipolari. Quando utilizzato con un driver unipolare motore passo-passo,vengono utilizzate tutte le sei derivazioni. Quando utilizzato con un driver motore passo-passo bipolare, i fili giallo e bianco presa centrale può essere lasciato scollegato (la coppia rosso-blu dà accesso auna bobina e la coppia nero-verde dà accesso all'altra bobina). Si consiglia di utilizzare come un motore passo-passo bipolare.

Dimensions

The following diagram shows the stepper motor dimensions in mm. The dimension labeled “length” is 48 mm. The output shaft has a length of 24 mm and a diameter of 5 mm, and it works with our 5mm universal mounting hub . Though not shown in the diagram, the output is a D-shaft with a section that is flattened by 0.5 mm. This is a NEMA 17-size motor.

Stepper Motor Applications

Stepper motors are generally used in a variety of applications where precise position control is desirable and the cost or complexity of a feedback control system is unwarranted. Here are a few applications where stepper motors are often found:

• Printers
• CNC machines
• 3D printer/prototyping machines
• Laser cutters
• Pick and place machines
• Linear actuators
• Hard drives
