Product Description:

The T720-012E59 is a brushless servo motor produced by Sanyo Denki for the T SANMOTION Servo Motors series. This compact unit is intended for industrial automation tasks that require accurate speed and torque regulation, such as small conveyor drives, indexing tables, and assembly robots. The motor pairs rare-earth magnets with a precision feedback device to maintain tight position control under varying loads. Its compact size also supports installation in machinery where the available mounting space is limited.

At its continuous operating point, this model provides a 200 W mechanical output while the shaft supplies 0.64 N·m of torque at 3000 rpm. To sustain that output, the winding operates at 80 V with a rated current of 3.4 A. The armature resistance is 2.8 Ω, which helps limit resistive losses, and the torque constant is 0.23 N·m/A. The rotor requires only 7.8 ms to reach 63% of a commanded speed change, supporting rapid indexing cycles. An outer diameter of 76 mm allows the motor to connect to compact gearheads or belt pulleys without spacer plates. These operating characteristics support controlled acceleration and steady torque delivery in compact motion systems.

For short operating bursts, the magnetic circuit provides a peak torque of 5.4 N·m. Static applications can use a continuous stall torque of 0.77 N·m without exceeding the motor’s thermal limits. The rotor can reach a maximum speed of 5000 rpm when the application requires faster motion. Position information is supplied by an incremental encoder that produces 2500 pulses per revolution across three channels. The encoder generates complementary A, B, and index signals through a line-driver output circuit, which supports noise-resistant signal transmission. The feedback assembly weighs 0.25 kg, helping preserve the motor’s fast acceleration response for pick-and-place equipment and semiconductor machinery.
