Product Description:

The T511T-174U is a compact servo motor manufactured by Sanyo Denki as part of the T SANMOTION Servo Motors series. It is intended for use in small positioning stages, labelers, and semiconductor handling modules where precise velocity and torque control are required. Coupled with a compatible drive, the motor translates electrical commands from a PLC into repeatable rotary motion for continuous-duty industrial automation.

During normal operation, the unit delivers a continuous mechanical output of 110 W. At this output, the shaft turns at 3000 rpm and maintains a steady torque of 0.34 N·m while the power stage supplies 2.0 A. The electromagnetic design provides a torque constant of 0.21 N·m/A, so proportional increases in phase current produce a predictable rise in torque. A winding voltage of 75 V establishes the nominal back EMF, and the 5.1 Ω armature resistance limits copper loss at the rated load. The frame has an outer diameter of 51 mm, allowing the motor to fit in dense multi-axis assemblies. For signal conditioning, an integral tachogenerator provides 7 V per 1000 rpm with 1% linearity and a winding resistance of 26 Ω. Its output requires a load resistance of at least 10 kΩ to maintain accuracy.

For transient demands, the motor can reach a shaft torque limit of 3.4 N·m, supplying short bursts of motion authority well above its continuous operating range. The continuous stall torque is 0.42 N·m, supporting static holding tasks without causing thermal overload. Dynamic performance is aided by an armature inductance of 3.2 mH, which influences the rate of current rise. The mechanical time constant is 4.3 ms, indicating how quickly the rotor accelerates toward the commanded speed. These response characteristics help the motor manage rapid duty-cycle changes and smooth starts in compact servo axes.
