Product Description:

The L404T-032 Servo Motor from the Super DC Servo Motors series of Sanyo Denki is a compact and efficient motor designed for precision control in industrial automation applications. It operates at a rated power of 22 watts and requires a supply voltage of 48V DC. This motor features a rated speed of 1600 revolutions per minute for having a smooth and consistent rotational output.

The L404T-032 servo motor supports a current rating of 0.85A. The encoder used in this servo motor is an optical incremental type typically with 500 pulses per revolution. It provides accurate position feedback essential for precise motion control systems. The Tachogenerator produces 3 millivolts of output voltage for each revolution per minute of the motor shaft. The motor casing is built for durability by using high-quality materials for extended service life. The L404T-032 servo motor includes an integrated gear mechanism to enhance torque and speed control. The insulation class is usually rated as Class B, allowing operation in temperatures up to 130 degrees Celsius. This motor can tolerate ambient humidity levels of up to 85% RH without condensation. It is designed to function at altitudes of up to 1000 meters above sea level.

The L404T-032 servo motor is resistant to vibrations up to 2.5G and can operate safely under 4.9 m/s² vibrations. It also complies with general protection standards against dust and minor moisture ingress. The shaft diameter and mounting dimensions of this servo motor follow standard NEMA frame compatibility. The winding resistance and inductance are engineered for stable torque delivery. It features color-coded wiring for easy installation and secure electrical connections. The cooling in the motor is achieved through natural convection without the need for an external fan.
