Frequently Asked Questions

What is the step angle and accuracy of this motor?

The JK42HS48 motor features a 1.8° step angle, ensuring fine positional control. Its step angle accuracy is ±5%, providing reliable precision for demanding applications like 3D printing and light CNC machinery where consistent movement is crucial for quality output and part accuracy.

What is the holding torque and current per phase?

This NEMA17 stepper motor delivers 5.5 kg-cm (approximately 0.54 Nm) of holding torque with a current of 1.5 Amperes per phase. This torque rating is suitable for driving axes on desktop 3D printers, small CNC routers, or robotic arms, effectively preventing missed steps under typical operational loads.

What kind of shaft does this motor have and why is it important?

The motor is equipped with a D-type shaft, which features a flat surface along its length. This design is crucial for securely mounting pulleys, gears, or couplings, preventing rotational slip under load and ensuring accurate power transmission from the motor to the driven component, vital for precision applications.

Can this motor be used for high-speed applications?

While capable of providing precise low-speed motion, this NEMA17 stepper motor is generally not optimized for extremely high-speed applications. Stepper motors inherently experience a drop in torque at higher speeds due to back EMF. It excels in tasks requiring high positional accuracy at moderate velocities, such as 3D printer extrusion or gantry movement.
