Product Description:
The part number 103M8332-2540 of stepping synchronous motors is designed for precise low‐speed, high‐torque applications. This specification delivers the exact control needed for demanding low-speed tasks. Frame/mounting options are available in NEMA 34 (ø86 mm) and NEMA 42 (ø106 mm) configurations. It allows the module to be integrated into different system layouts without modification. The rated torque typically ranges from approximately 1.0 Nm (141.6 oz-in) up to 3.7 Nm (523.9 oz-in). The motor’s rated speed is commonly offered at 60 to 72 min⁻¹ for the low-speed design. This speed supports applications that require deliberate, controlled motion.
The frequency setting (digital) is tuned for digital command inputs with rated frequency settings typically at 100–120 Hz. The setting improves responsiveness to control signals. Rated current varies from about 0.28 A up to 0.50 A; such current options help optimize power consumption. The drive’s rotor inertia options include values around 1.55 kg·m² (3.4 oz·in-s²). This inertia value ensures stable operation during dynamic load changes. Shaft dimension (l1) is available in sizes such as 2.45 mm with alternatives at 3.77 mm or 5.08 mm. It enables compatibility with standard industrial power supplies. The storage temperature is rated from -20°C to 65°C for short-term conditions and ensures safe transportation and temporary storage.
Protective functions of Sanyo Denki’s 103M8332-2540 unit include safeguards against overcurrent, overvoltage, undervoltage, electronic thermal faults, temperature abnormalities, and ground faults. This array of protection measures minimizes risk during unexpected operating conditions. The carrier frequency range is adjustable from 2.0 kHz to 14.0 kHz and it allows fine tuning for optimal drive performance. Rated acceleration is approximately 0.15 seconds to full step speed. The quick acceleration benefits applications requiring rapid start-up. Noise level remains below 70 dB during operation. This low noise output supports quieter industrial environments. With a rated mechanical life of 50,000, it enhances motor’s operating hours.
