Product Description:
The T404T-012 servo motor manufactured by Sanyo Denki belongs to the T SANMOTION Servo Motors series. This DC brush servo unit is intended for motion axes that require low power with precise speed and torque regulation in industrial automation machinery. The compact 41 mm flange allows direct mounting in small mechanisms such as indexing tables or semiconductor handlers. Its integrated tachometer generator supplies velocity feedback to the drive amplifier for closed-loop control, allowing the system to correct speed deviations as the mechanical load changes.
It delivers a rated mechanical output of 0.04 kW, representing the continuous shaft power available to the load at the nominal operating point. At a rated speed of 3000 rpm, this power provides moderate shaft torque suited for light pick-and-place actuators. The continuous stall torque is 0.14 N·m, indicating the torque that can be maintained without exceeding the motor’s temperature limits. The peak stall torque rises to 0.76 N·m for brief acceleration periods or load disturbances. The armature operates from a DC bus of 72 V, so the connected drive must supply this voltage with suitable current regulation. Lead wires exit the housing instead of using a connector, simplifying direct termination at a soldered connection or terminal block in compact equipment.
Dynamic response is aided by a rotor inertia of 0.084 × 10⁻⁴ kg·m², allowing rapid speed changes with modest control effort. The enclosure has an IP43 rating, providing protection against solid objects larger than 1 mm and water sprayed at angles up to 60 degrees from vertical. The motor has a mass of 0.49 kg, minimizing the load on linear stages and reducing the required support structure. Power conductors and feedback leads are furnished as a bundle that extends 1000 mm, providing flexibility when the wiring is routed through cable tracks. The motor has a D-shaped output shaft for positive engagement with a compatible coupling. The design does not include an oil seal, so the machine enclosure should prevent oil, dust, and other contaminants from reaching the shaft opening.
