Product Description:
The T404-012EL8 is a brushless servo motor manufactured by Sanyo Denki as a member of the T SANMOTION Servo Motors series. It serves as the prime mover in compact automation stages where rapid position control, limited installation space, and low system inertia are required. An incremental PP031 encoder provides 1,000 pulses per revolution so that a drive controller can maintain precise motion loops during assembly, inspection, or laboratory handling processes.
The motor delivers its continuous mechanical output with a rated armature voltage of 72 V and a rated current of 1.0 A. Under these electrical conditions, it produces 40 W of shaft power while sustaining a rated speed of 3000 rpm. The corresponding rated torque is 0.080 N·m, based on the magnetic design and a torque constant of 0.174 N·m/A. Phase resistance is 18.6 Ω, which determines the voltage drop per phase and influences the temperature rise during continuous operation. The voltage constant of 18.2 × 10-3 V per min-1 relates shaft speed to back electromotive force and helps the drive maintain correct commutation. A 41 mm outer diameter allows the frame to mount directly onto miniature gearheads or flange plates without additional spacers.
Dynamic response includes a peak torque of 0.319 N·m, enabling brief acceleration bursts beyond the continuous limit. Current builds in the windings with an electrical time constant of 0.35 ms, while the rotor responds according to a mechanical time constant of 4.8 ms. These response times support high-frequency indexing where commands change rapidly. The assembly weighs only 0.65 kg, reducing the supported mass in compact equipment. Its rotor inertia is 0.092 × 10-4 kg·m², which minimizes loading on miniature ball screws or timing belts during rapid reversals.
