Product Description:
The T402-011EL8 is a compact servo motor manufactured by Sanyo Denki as part of the T SANMOTION Servo Motors series. It is intended for industrial automation tasks that require precise torque and speed control, such as miniature actuators, inspection tables, and electronic assembly heads. By converting drive-generated current into regulated shaft motion, the motor helps machines follow programmed position, velocity, or force profiles with minimal delay. Its compact form is suitable for motion systems where installation space is limited but responsive control is still required.
An electrical time constant of 0.35 ms allows the armature current to respond quickly to commands, enabling rapid closed-loop corrections. The frame has an outer diameter of 41 mm, allowing placement in densely packed mechanical layouts. The phase resistance is 3.2 Ω, which affects current flow when voltage is applied to the winding. A rated armature current of 1.9 A indicates the continuous electrical load the motor can support under rated operating conditions. The incremental PP031 encoder provides a line-driver output, and its resolution of 1000 P/R supplies detailed position data for smooth interpolation. A mechanical time constant of 7.1 ms indicates how quickly the rotor speed responds to a change in torque, supporting short settling times in repetitive motion cycles.
The motor has a continuous power rating of 23 W at a shaft speed of 3000 rpm. Its rated torque is 0.061 N·m, making it suitable for mid-speed applications with relatively light mechanical loads. With a torque constant of 0.047 N·m/A, commanded current can be used to estimate the resulting motor torque during control calculations. The armature operates at 20 V under nominal load, while the per-phase back-EMF constant is 4.9 V per 1000 rpm. This back electromotive force increases with shaft speed and must be considered by the drive during acceleration and deceleration. Encoder feedback allows the controller to monitor shaft movement and correct deviations from the commanded motion profile.
