Product Description:

Sanyo Denki is a world known manufacturer of automation equipment. One of their leading product is T720-012EL8 Servo Motor which belongs to the SANMOTION T series. This motor is known for its precision motion control applications.

This T720-012EL8 servo motor requires 80 V of supply voltage to operate and it generates 200 W of output. The servo motor operates at 3000 min⁻¹ and provides a torque output of 0.64 Nm. The motor provides reliable service because of its 5.4 Nm instantaneous maximum torque ability throughout demanding operational conditions. This servo motor delivers stable operation due to its efficient and durable design at a stall torque of 0.77 Nm. The rated armature current of this motor is 3.4 A, while the standstill current is 3.7 A. The maximum rotation capability of this device reaches 5000 min⁻¹ to enable various operating speeds. The T720-012EL8 servo motor features the torque constant and voltage constant of 0.23 N•m/A and 24.2×10⁻³ V/min⁻¹. This motor demonstrates suitability for controlled acceleration thanks to its rotor inertia measurement of 0.147×10⁻³ kg•m². A resistance of 2.8 Ω found in the armature winding enables proper power distribution to maintain thermal stability.

The T720-012EL8 servo motor integrates an incremental encoder as a component for exact mechanical positioning. The motor maintains its operation through an IP43 protection grade, which stops both moisture and dust from entering. The 1000 mm wires (lead) are supplied along with this servo motor. The compact device features 76 mm flange dimensions and 2.05 kg weight to deliver high-performance ratings with its small design. The motor operates reliably between temperatures between 0°C and 40°C because of its designed operating parameters.
