Product Description:

The T406-012EL8 is a low-power servo motor from Sanyo Denki’s T SANMOTION Servo Motors series. This compact rotary unit converts electrical energy into controlled mechanical motion for positioning axes, small pick-and-place heads, and other light-duty automation stages that need repeatable velocity and torque. A 41 mm square flange allows direct frame mounting, and the D-shaped output shaft provides positive engagement with small pulleys or couplings.

The motor sustains a continuous stall torque of 0.175 N·m, providing steady force for static holding or low-speed operating conditions. During regular operation, its rated mechanical output reaches 0.06 kW, and it maintains that power while turning at a nominal speed of 3000 rpm. The armature is supplied with 70 V DC to deliver this performance, matching the voltage class used by many miniature servo drives. An enclosure protection rating of IP43 shields internal components against solid particles larger than 1 mm and angled water spray, making the unit suitable for clean industrial cabinets. Electrical connections use preterminated lead wires, with the three-phase power and encoder conductors exiting the housing through 1000 mm leads. This arrangement simplifies connection to terminal blocks without requiring additional extension cables.

For rapid starts and stops, the motor can generate a peak stall torque of 0.441 N·m, supporting brief overloads such as acceleration bursts. Dynamic response is assisted by a rotor inertia of 0.116 × 10⁻⁴ kg·m², which limits overshoot while allowing quick speed changes. Position feedback comes from an incremental encoder with a resolution of 1000 P/R, supplying the drive with quadrature signals for fine motion control. The motor has a mass of 0.75 kg, reducing the load placed on linear slides or robotic joints. The shaft does not have an oil seal, so it should be oriented away from direct exposure to fluids.
