Stepper motor Joy-IT NEMA23-02 — NEMA23, 200 steps, 1.2 N·m, 3 V DC, 2.5 A, 56×56×56 mm
The Joy-IT NEMA23-02 is a NEMA23 stepper motor with 200 steps per revolution (1.8° per step) designed to deliver consistent incremental motion and reliable holding torque. With a rated DC voltage of 3 V, a winding impedance of 1.2 Ω and nominal phase current of 2.5 A, this two-phase motor produces a maximum holding torque of 1.2 N·m within a compact 56×56×56 mm housing. Its mechanical size and electrical characteristics make it suitable for systems that require precise positioning and repeatable stepwise movement.
The stepper motor provides precise open-loop positioning with 200 full steps per revolution and a defined step angle of 1.8°, enabling accurate incremental control without the need for feedback in many applications. The 1.2 N·m holding torque ensures stable holding and resistance to detent forces during pauses or low-speed operation. Low rated voltage and defined winding impedance support straightforward driver selection and predictable current control. The compact cubic form factor simplifies mounting in constrained mechanical designs.
Install the motor on a suitably rigid mounting surface using the manufacturer-recommended bolt pattern for NEMA23 frames and ensure correct alignment with the driven mechanism to avoid side loads on the shaft. Select a compatible stepper driver able to supply up to 2.5 A per phase and configure microstepping and current limits according to the motor's impedance and your application's torque and smoothness requirements. Provide appropriate electrical connections for the two windings and verify wiring polarity to achieve the desired rotation direction. During commissioning, tune acceleration and maximum step rate to prevent missed steps and excessive heating.
Use a current-limiting stepper driver and set thermal management measures—such as heat sinks or controlled duty cycles—when operating near rated current. For prolonged holding or high-speed operation, verify motor and driver temperature and allow cooldown periods as needed. If higher torque or closed-loop control is required, consider pairing the motor with microstepping drivers or external encoders at the system level.
