APPLICATION GUIDANCE
For compact positioning mechanisms, lightweight feed mechanisms and compact instruments. Suitability must be checked against actual load, speed and driver settings.
CUSTOMIZATION
Shaft machining, cable length and connector options can be discussed. Pulleys, gears, gearboxes, brakes and closed-loop encoders require a separately confirmed configuration and are not included in this standard motor.
FAQ
Q: What is the full factory model?
A: 42BYGH2303-A-22DPH; sales model 42BYGH2301.
Q: Can the motor be connected directly to a DC 12–24V supply?
A: Use a suitable current-regulated stepper driver. The winding rated voltage is DC 4.2V and is different from the driver supply voltage.
Q: How do I confirm price and availability?
A: Send the model, quantity and configuration through the inquiry form. Price, availability and delivery time are confirmed for the order.
