Product Description:
Designed by Sanyo Denki, the SLO‑SYN drive U508BN-012E operate at a rated armature voltage of 75 V, aligning it with common drive platforms and simplifying electrical compatibility. This also delivers a rated torque of 0.177 Nm, providing reliable performance for low-load scenarios. Its momentary maximum stall torque of 0.441 Nm enables the device to handle transient load surges without mechanical disruption.
Featuring a mechanical time constant of 7.4 ms, the motor responds quickly to speed changes, ensuring swift control adjustments. Its rated output of 57 W further offers balanced power delivery for compact motion systems. With a total weight of 0.8 kg including the encoder, this module supports lightweight installations where space and mass are limited. Running at a rated speed of 3000 min⁻¹, it fits seamlessly into standard automation routines. The induced voltage constant of 19.1 mV/min⁻¹ allows for predictable back-EMF behavior, aiding in voltage regulation and control feedback. Additionally, a rated armature current of 1.14 A enables stable torque generation while preserving thermal stability. An electrical time constant of 0.45 ms ensures rapid current response, essential for fine-tuned control.
With a torque constant of 0.183 Nm/A, the unit provides a consistent torque-to-current ratio, supporting accurate torque regulation. It allows a momentary maximum stall current of 2.8 A, giving short-term margin for high-load situations. The armature resistance of 11.7 Ω defines thermal characteristics during operation and supports temperature predictability. According to technical data, the drive achieves a peak efficiency of 82% at nominal load. Additionally, a thermal resistance of 3.2 K/W enables consistent thermal performance under steady-state operating conditions.
