Product Description:

The L404-012E17 Servo Motor is a product of Sanyo Denki that works with an input voltage of 75 V to offer a consistent electrical profile for controlled performance in servo-controlled systems. The stall torque of this servo motor is continuously rated at 0.24 Nm to provide a stable torque output under continuous load conditions without the risk of overheating or torque loss.

The L404-012E17 servo motor operates at a 3000 min⁻¹ rotational speed to enable high-speed applications that require fast motion cycles and reliable rotational accuracy. This servo motor’s 40 W output power is capable of delivering light mechanical loads that necessitate precise and continuous actuation. A current draw of 0.9 A of this motor provides energy-efficient performance during full-load operation and minimizes system power consumption. This servo motor has a voltage constant of 19.1 V/min⁻¹ to enable dependable speed control in applications with voltage-based control methods and ensure compatibility with different control amplifiers. The rotor inertia of this motor is 0.000013 kg·m², enabling rapid acceleration and deceleration without excessive mechanical opposition, important for high-speed directional changes. The shaft type of this servo motor is cylindrical with a keyway slot to ensure safe mating with driven mechanical parts and reduce backlash during the transmission of torque.

The mounting type of this motor is face-mount flange with 4x through-hole bolts for a safe and vibration-resistant mounting in equipment frames or mechanical enclosures. The L404-012E17 motor can be mounted up to a maximum altitude of 1000 meters above sea level, thereby maintaining accurate functioning without loss in air-cooled applications. This servo motor is specifically meant for operation within an ambient temperature zone of 0°C to 40°C, which provides thermal stability and maximum motor operation within climate-controlled systems.

Frequently Asked Questions about L404-012E17:

Q: How does the 0.000013 kg·m² rotor inertia help the motor?

A: The low rotor inertia enables quick acceleration and deceleration. This improves response time in systems needing fast motion changes.

Q: Why is a key slot provided on the cylindrical shaft of L404-012E17?

A: The key slot prevents shaft slippage during torque transfer. It ensures secure coupling in rotational assemblies.

Q: What is the benefit of using 4x through-hole bolts in mounting?

A: They offer high mechanical stability and resist vibration during high-speed operation. This ensures long-term alignment and structural integrity.

Q: How does the 19.1 V/min⁻¹ voltage constant affect motor performance?

A: It allows consistent speed regulation in voltage-based feedback systems. This results in precise velocity control in automation tasks.

Q: Why is the ambient temperature range limited to 0°C to 40°C?

A: The motor components are thermally optimized for this range. Operating beyond it may affect insulation and motor efficiency.
