Product Description:
The 21-3450D200-E03BC Stepper Motor is a NEMA 23 motor engineered for precision applications. This model is manufactured with advanced materials and technology. With a robust build, it is designed to deliver exceptional torque, thermal dissipation and long service life.
This Pacific Scientific 21-3450D200-E03BC stepper motor features an all in one molded stator assembly that enhances mechanical stability and reduces vibration. The neodymium iron boron rotor magnets provide strong magnetic flux. The oversized 30 mm bearings in this motor significantly increase bearing fatigue life by 400 % compared to standard 22 mm bearings. This ensures prolonged durability and lower maintenance. It includes a new polymer encapsulated stator for improved thermal efficiency and a polymer end bell with threaded inserts that enhances cooling and mounting flexibility. The exposed laminations aid thermal dissipation that reduces heat buildup and extends motor lifespan. Additionally, Class B insulation ensures safe operation under high temperatures. The precision ground rotor OD and honed stator ID ensure a concentric air gap that improves motor efficiency and performance.
The 21-3450D200-E03BC stepper motor supports multiple drive shaft modifications and has the largest available shaft diameter (0.375") in a NEMA 23 stepper capable of withstanding high radial and axial loads. The integral electrical receptacle with high retention force allows secure connections, and it supports optional encoders and rear shaft extensions for versatile applications. Sigmax® technology is available in this motor that incorporates flux concentrating samarium cobalt magnets to achieve maximum torque and acceleration. The rugged end bell with encapsulated windings and electrical connectors utilizes high tech polymer for enhanced reliability. The octagonal shape of this motor simplifies automated assembly, making it suitable for industrial automation, robotics and high precision machinery.
