Size: NEMA 14 refers to the motor frame size, which is 1.4 inches or approximately 35 mm square. Stepper motors are categorized into different NEMA sizes based on their physical dimensions.

Torque: The motor you mentioned has a holding torque of 90 mN.m (millinewton meter). Holding torque is the amount of torque the motor can produce when stationary, without losing steps.

Current: The motor has a rated current of 1.1 Amps. This indicates the maximum current the motor windings should be supplied with to achieve the specified torque.

Closed-loop: The closed-loop feature means that the motor incorporates an encoder for position feedback. Unlike traditional open-loop stepper motors, closed-loop steppers can detect and correct for step loss or position errors. The encoder provides feedback to the control system, allowing it to adjust the motor's operation in real-time, ensuring accurate positioning.
