3. Prinsip Kerja & Komposisi Struktural
The NEMA compact series operates on a concentric epicyclic gear layout. The stepper or servo motor drives a small central roda gigi matahari. This sun gear meshes with three roda gigi planet that are confined within a stationary outer roda gigi cincin. As the planet gears rotate, they turn the planet pembawa, transferring high torque to the output shaft. By locking directly onto standard NEMA faceplates, it prevents coupling misalignment and ensures perfect concentricity.

4. 5 Keunggulan Utama
š Plug-and-Play Assembly
Pre-machined flanges and clamping collars fit standard NEMA motors perfectly, requiring no custom adapter plates.
āļø Lightweight Aluminum Housing
Aircraft-grade aluminum casing reduces total weight, crucial for dynamic gantry systems and robotic arms.
šÆ Prevents Stepper Stall
Multiplies the low-speed torque of stepper motors, completely eliminating skipped steps during heavy loads.
š High Radial Support
Dual ball bearing output design handles tight timing belt tension directly on the shaft.
š”ļø Dust-Proof Sealing
IP54 baseline sealing protects internal gears from sawdust, metal shavings, and facility debris.
5. Struktur & Teknologi Material
To balance weight and strength, Ever Power employs an anodized aluminum alloy for the main external housing, which acts as an excellent thermal conductor to pull heat away from the stepper motor. The internal gears, however, are cut from carbon steel and nitro-carburized to provide a wear-resistant surface while maintaining a tough inner core to absorb reversing impacts.
6. Skenario Aplikasi Umum
- Medical Liquid Dispensing: Penggunaan: Syringe pumps. Prinsip: The gear ratio allows the stepper motor to make micro-movements, ensuring highly accurate volumetric dosing without stalling.
- Desktop CNC Routers: Penggunaan: X/Y axis gantry drives. Prinsip: The high torque prevents tool deflection in wood and soft metals, while the compact size keeps the machine footprint small.
- Automated Camera Sliders: Penggunaan: Cinema production. Prinsip: The smooth helical gear engagement provides jitter-free camera movement essential for professional filming.
7. Panduan Seleksi
Selecting the right NEMA gearbox requires a few specific details:
- Identify your current motor’s NEMA frame size (e.g., NEMA 23).
- Measure the motor’s exact shaft length and diameter (usually 6.35mm or 8mm for NEMA 23).
- Determine the holding torque of your motor and multiply it by the desired gear ratio and an efficiency factor (usually 0.90) to ensure the gearbox can handle the final output.
- Check the radial load if applying a timing belt pulley.

12. Pertanyaan yang Sering Diajukan (FAQ)
Q: Do I need a special coupling to attach my stepper motor?
A: No. Our gearboxes feature an integrated clamping collar on the sun gear. You simply insert your motor shaft and tighten the tension bolt.
Q: Can these gearboxes be back-driven?
A: Due to high efficiency, 1-stage planetary units can be back-driven. If you need self-locking capabilities, a worm gear or a mechanical brake is required.
