STEPPERONLINE Nema 17 Pancake Stepper Motor
The STEPPERONLINE Nema 17 pancake motor provides compact form factor and reliable torque for small to mid‑range automation tasks. With a 26Ncm holding torque, it is a bipolar stepper motor featuring two phases and four leads. The 1.8° step angle yields precise positioning, making it suitable for 3D printer extruders, small CNC mills, or precise actuators in lab setups. Its dimensions (42×42×30mm) keep it compatible with compact motor mounts and quick‑swap configurations in multi‑axis rigs. The motor’s 200 steps per revolution supports smooth incremental motion when paired with appropriate drivers.
Rtelligent EtherCAT Driver With Nema 23 Closed Loop (3.0Nm)
This combination pairs a high‑torque Nema 23 closed‑loop motor with an EtherCAT drive and a built‑in encoder. The motor delivers 3.0Nm holding torque and operates at 1.8° per step with a 4000ppr encoder for high precision and lossless stepping. The driver supports CiA402 and CoE protocols and is compatible with 24–80V DC supplies, providing robust performance in CNC machines and offline control scenarios. The compact enclosure (134×82×29mm) allows straightforward integration into existing control cabinets.
Rtelligent EtherCAT Driver With Nema 23 Closed Loop (1.3Nm)
The 1.3Nm variant provides a balance between torque and motor size, ideal for compact CNC and automation tasks where space is at a premium. The built‑in encoder with 4000ppr ensures precise positioning, and the EtherCAT drive supports a wide voltage range (24–80V) with a 6A output current. With CiA402 and CoE compatibility, this setup enables reliable fieldbus communication in offline or online configurations, improving control loop performance in flexible manufacturing cells.
Rtelligent EtherCAT Driver With Nema 23 Closed Loop (2.3Nm)
The 2.3Nm variant provides higher torque for demanding applications such as heavier milling, larger printers, or fast, forceful axis moves. Like the other models, it uses a built‑in encoder with 4000ppr for high precision and supports offline operations. The driver accepts 24–80V DC and offers up to 6A output current, supporting CiA402/CoE protocols for robust fieldbus integration. The compact module is designed for straightforward installation alongside compatible motors in multi‑axis systems.
Buying Guide: 3 Phase Extension Leads And Motor Control Considerations
When selecting three‑phase extension leads and companion motor systems, several factors influence performance, safety, and long‑term reliability.
- Voltage and current ratings: Ensure the extension lead and driver can handle the system’s voltage (24–80V in EtherCAT setups) and peak currents. Mismatches can cause voltage drop and heat buildup.
- Phase configuration and wiring: 3‑phase power requires correct phasing and grounding. Use properly rated cables and connectors to prevent arcing or energizing faults in motor drivers.
- Torque and speed requirements: Higher torque motors (e.g., 2.3Nm) demand drivers with adequate current capacity. Match motor torque to mechanical load to avoid stalling and missed steps.
- Encoder resolution: Built‑in encoders (e.g., 4000ppr) improve precision and allow closed‑loop control to reduce missed steps. Ensure your control software supports CiA402/CoE standards for seamless integration.
- Communication protocol: EtherCAT and CANopen over EtherCAT (CoE) provide fast, deterministic control. Verify compatibility with your existing PLC, CNC controller, or motion controller.
- Physical footprint and mounting: Check motor dimensions and driver enclosure sizes to ensure fit within existing enclosures and mounts. Compact designs help in space‑constrained installations.
- Offline capability: Some drivers offer offline operation, enabling basic control without a live fieldbus. This can be advantageous for testing and maintenance scenarios.
- Protection and safety: Look for motors and drivers with protective features (overcurrent, thermal, short‑circuit) and ensure proper cable management to prevent damage during operation.
- Cable length and routing: Longer extension cables can introduce resistance and latency. Choose lengths that minimize voltage drop while meeting your installation layout.
- Certifications and warranty: Prefer devices with recognized certifications and a clear warranty policy to ensure reliability and support over time.
