XT404T-116
by Sanyo Denki
The Sanyo Denki XT404T-116 servo motor is a precision motion control device manufactured by Sanyo Denki and belongs to the T SANMOTION Servo Motors series. This compact unit delivers a rated output of 40 W and operates at a rated rotating speed of 3000 rpm, with an instantaneous maximum torque of 0.76 N·m for short bursts of high acceleration. Designed for industrial automation tasks, it provides reliable speed and torque control in applications where space constraints demand a small yet powerful motor.
Building on its compact form, the XT404T-116 offers a rated armature voltage of 36 V and a rated armature current of 1.9 A, ensuring efficient energy conversion within tight voltage tolerances. It achieves a continuous stall torque of 0.14 N·m and overcomes internal resistance characterized by a friction torque of 0.019 N·m, delivering smooth low-speed response. The motor reaches a maximum rotating speed of 5000 rpm when unloaded and features a rotor inertia of 0.0084×10⁻³ kg·m² to optimize dynamic performance. A thermal resistance of 3.6 K/W and a thermal time constant of 20 min safeguard against overheating during continuous operation, while the plain-shaft design allows integration with standard couplings and servo amplifiers.
Durability and compatibility are ensured by its mass of 0.4 kg, a motor protection class of IP43, and an insulation classification of F, making it resistant to dust ingress and temperature stresses up to 155°C. The black protective coat on the housing guards against corrosion in indoor environments, and the motor holds CE certification, indicating compliance with EU health, safety, and environmental standards. With a compact footprint and high efficiency, the XT404T-116 enhances productivity, energy savings, and reliability in industrial automation settings, delivering precise positioning and rapid response for modern manufacturing equipment.
